What are split flanges used for?
Split flanges are primarily used in piping systems to connect two sections of pipe securely. They allow for easy assembly and disassembly, making maintenance and repairs more convenient. Their design helps to accommodate thermal expansion and contraction, ensuring a reliable seal.
How do I choose a split flange manufacturer?
When selecting a split flange manufacturer, consider their experience, reputation, and quality standards. Look for certifications and customer reviews to gauge their reliability. It’s also important to check their range of products and whether they can meet your specific requirements.
What materials are commonly used for split flanges?
Split flanges are typically made from materials like stainless steel, carbon steel, and alloy steel. The choice of material depends on the application, including factors like pressure, temperature, and corrosion resistance. Always consult with your manufacturer to select the best material for your needs.
Can split flanges be customized?
Yes, many manufacturers offer customization options for split flanges. You can request specific sizes, materials, and designs to fit your unique application. Customization ensures that the flanges meet your exact specifications and performance requirements.
What is the typical lead time for split flange orders?
Lead times for split flange orders can vary based on the manufacturer and the complexity of your order. Generally, standard orders may take a few weeks, while custom orders could take longer. It’s best to communicate directly with the manufacturer for accurate timelines.
Depending on your application, we offer a variety of different flange protectors. Our flangeDOTS® are self adhesive and are simple to apply just by peeling the backing off and sticking to the equipment you want to protect. They stay put, unlike plastic push-in protectors. Our self adhesive protectors also have a VCI additive mixed into the adhesive, for added rust and corrosion protection. Our flangeBUMPERS® are a ridge form of flange protection that are easily attached with zip ties or multiNUTS. They are also weatherproof and highly UV resistant, which can’t be said for many of the other competitors. flangeBUMPERS® are extremely lightweight and do not require a lift when you are installing larger sizes.
A Upon inspection using PCC-1 inspection criteria, if the gasket sealing surface does not meet minimum criteria, PCC-2 allows for machining/resurfacing to bring the flange face sealing surface back to within acceptable criteria. Machining a flange removes a layer of metal from the flange and cuts a new surface profile (gramophone) back onto the surface of the flange.
Specialized refacing equipment is required to bring the raised face surface profile back to within ASME B16.5/B16.47 criteria. Refacing machines are OD/ID mounted onto the flange during the resurfacing process. Some of the more common refacing equipment suppliers are listed below
- E.H WACHS
- HYDRATIGHT
- MIRAGE MACHINES
- CLIMAX
P3- GIT stands for Gramophone Inspection Tool. This tool helps you identify weather or not your flange passes inspection. As you can see this one is used on an 8” flange with either a 150 or 300 lbs pressure class.

The cut-out window mimics where the gasket sealing surface will come in contact with the flange face. The cut-out area is the most critical area for inspection on the flange face. Any damage found in this area could result in possible re-facing. However, any damage on the flange face outside the window is acceptable and will pass inspection. The marks on the side of the GIT are in 10% percent increments that represent the gasket sealing surface. Refer to the asme PCC-1 table for heavy, moderate, and light damage percentages. We are using the P3GIT to show how a spiral wound gasket would sit on the flange face surface area.
Start by lining up the top of the GIT tool with the raised face of the flange. We are drawing where the gasket would sit on the face to see if the imperfections are on the critical surface area. Next, we are marking visible damage and using to tool to see if it is within the critical gasket sealing surface. If the damage does NOT fall inside the window, then the imperfection would pass inspection.
If a flangeDOT does not stick to the flange face, the most common issue would be a dirty flange face. Cleaning the flange face would be the first course of action. If a flangeDOT is placed over a rusted flange face, eventually the flangeDOT will begin to peel off. The flangeDOT will literally peel rust from the face and not adhere correctly. Another common cause is the flange face has residual oil from cleaning. If a product such as WD-40 is used to clean a flange face and a degreaser is not used to remove the residual product, the flangeDOT will not seal/stick correctly.
Long story short…clean the flange face. If your flange face looks like the one below, clean the flange face before applying a flangeDOT.
To put it plain and simple, NO.
flangeDOTS are not designed to be used for long-term preservation on their own. Our self-adhesive protector is excellent for short-term applications such as blasting, painting, shipping, and short-term storage.
In order for flangeDOTS to be used for long-term preservation they MUST be combined with our flangeBUMPER or flangeBUMPER+Gasket . This system is known as our Patented Preservation System that prevents corrosion of the flange face, keep debris out of your assets, and provides rigid impact protection.
A flange face will need corrosion protection (especially on carbon steel flanges). flangeDOTS+VCI will cover the flange face while providing a corrosion inhibitor embedded in the adhesive. If a “stand alone” corrosion inhibitor is required, Cortec VpCI-391 is great for long term indoor/outdoor use. A rigid protector is also required impact protection. flangeCORR attached with multi-NUTS/Bolts/Zip Ties provides medium impact protection while a flangeBUMPER attached with multi-NUTS/Bolts/Zip ties provides high impact protection.
Storage flanges indoor when possible. If indoor storage is not available, ensure flanges are stored on dunnage 4-6” above the ground. Apply a flangeDOT+VCI or a flangeMAG during the welding process to ensure your flange is not damaged during fabrication. Complete all flange connections (fully torqued/tensioned) within 72 hours of flange makeup…DO NOT LOOSE BOLT FLANGES.
We offer products for a variety of different application such as...
- Corrosion Protection
- Impact Protection
- Shipping Protection
- Storage conditions/dunnage height Protection
- Welding Protection
1️⃣ Proper Installation: Always follow the manufacturer's specifications for torque settings and installation procedures. Incorrect installation can lead to leaks and premature failure.
2️⃣ Material Selection: Choose the right flange material for your application. Consider factors like temperature, pressure, and the type of fluid to ensure compatibility.
3️⃣ Regular Inspections: Schedule routine inspections to identify any signs of wear, corrosion, or misalignment. Early detection can save time and costs in the long run.
4️⃣ Use of Gaskets: Never underestimate the importance of high-quality gaskets. They provide a seal that prevents leaks and protects the flange from damage.
5️⃣ Invest in flange protection: Investing the proper flange protection will save you time by avoiding re-work and prevent your flanges from getting damaged during short and long-term storage.
6️⃣ Environmental Considerations: Protect flanges from harsh environmental conditions. Use covers or insulation where necessary to avoid exposure to extreme temperatures or corrosive substances.
FME is the process of preventing outside debris from entering critical areas such as equipment, machinery, or systems. Any object or material that enters a critical area and does not contribute to its purpose is considered outside debris. This debris could range from a variety of different materials such as tools, parts, dust, liquids, chemicals, etc.
To establish effective FME measures your organization should consider the following key steps:
- Conduct a thorough risk assessment to identify frequent or potential areas of concern (critical systems and fluid codes).
- Develop clear FME procedures that align with your team and industry best practices.
- Provide comprehensive training to employees on FME protocols and guidelines.
- Regularly inspect FME practices to ensure compliance and effectiveness.
There are a wide variety of products on the market to help prevent contamination, protect your equipment and uphold FME policies and procedures. These products include:
- flangeDOT – A self-adhesive protector
- flangeBUMPER – A rigid protector
- flangeBUMPER+Gasket – A rigid protector that provides a watertight seal
- paddleMAG – A magnetic protector with safety handles
- pipeCOVER – A pipe protector that easily folds down
You are going to need a drill or screwdriver, a batROLL, for this size of flange small & medium multiNUTS, and a flangeBUMPER. This is what hydro jetting looks like without a flangeBUMPER on. This is a major safety hazard!
Typically, during hydro jetting like this you are required to rope off a 15ft exclusion zone in all directions. Meaning no one is allowed to work within this 15ft radius for safety. Now we are going to apply our flangeBUMPER and shrink that 15ft exclusion zone to only 3ft! We are attaching the medium multiNUTS backwards to ensure that nothing touches the flange face. Then we will secure the flangeBUMPER onto the pipe spool with our small multiNUTS facing the correct way, with the smallest part of the multiNUTS facing the bolt hole.
Finally, we are going to mask off the top of the flange bumper with a piece of bat tape. Make sure that you do not wrap it all the way around, you want an opening at the bottom so that the water can fall out. Now, check out the different our flangeBUMPER makes! We will finish it off by drying the pipe with an air compressor to ensure that no water is left inside. And now the inside of our pipe is nice and clean.
You are going to need a drill or screwdriver, a batROLL, for this size of flange small & medium multiNUTS, and a flangeBUMPER. Here we have our mock pipe spool and a bucket to catch the debris. As you can see the inside of our pipe is dirty, so we are going to blow it out with air.
This is our first attempt without the flangeBUMPER. All the debris missed the bucket and shot straight out. This serves as a major safety hazard and typically during velocity blows like this you are required to rope off a 15ft exclusion zone in all directions. Meaning no one is allowed to work within this 15ft radius for safety. Now we are going to apply our flangeBUMPER and shrink that 15ft exclusion zone to only 3ft!
We are attaching the medium multiNUTS backwards to ensure that nothing touches the flange face. Then we will secure the flangeBUMPER onto the pipe spool with our small multiNUTS facing the correct way, with the smallest part of the multiNUTS facing the bolt hole.
Finally, we mask off the top of the flangeBUMPER with a piece of batROLL. Make sure that do NOT wrap the batROLL all the way around. You want an opening at the bottom for the debris to fall out off. And now your pipe spool is ready for a velocity blow!
A flangeDOT is the best way to protect a flange during the blast and paint process. flangeDOTS are cut to ANSI pipe sizes and trimming/masking is not required. flangeDOTS are peel and stick taking only seconds to apply. Traditionally masking tape is cut to cover the flange face during the blast and paint process. The masking process takes time and mistakes are often made. Cutting a rectangular piece of tape into a circle with a sharp instrument is not a good idea for both your fingers and the flange face. Keep in mind, the chlorides in the glue of most masking tapes can damage stainless steel and exotic material flanges. The adhesive in flangeDOTS does not contain chlorides and is safe for applications on carbon steel, stainless-steel, P-91, and P-11 materials.

Tools: flangeBUMPER, flangePORTHOLE, flangeBUMPER+Gasket, pipeCOVER
- Typically long-term preservation lasts for 24 months or longer.
- Our tools we created for this application provide rigid impact protection and keep the pipe interior clean.
- These tools work best for long-term storage in a warehouse or laydown yard, and protection your assets in harsh weather conditions.
In order to properly preserve a valve, we are using a Cortec VpCI- 101 emitter, and we stick it to the back of our flangeDOT, doing this will ensure that the emitter will not interfere with the valve seat.
To protect this for medium-term preservation you would need to attach a flangeCORR on top of the dot. You just align the flange CORR with the bolt holes on the valve and use multiNUTS and screws to secure it flush to the flange face. This system would provide preservation for up to 12 months.
Now to protect this valve for long-term preservation would need to attach a flangeBUMPER on top of the dot. This offers more ridged impact protection and will provide preservation for up to 24 months and over. You attached the flangeBUMPER in the same way, align it with the bolt holes on the ball valve and attached it with multiNUTS and screws.
