Weldless Connections & Quickflange - Frequently Asked Questions (FAQs)

Weldless connections are a type of pipe connection method that doesn’t require welding. They are often used in industries where quick and safe pipe connections are needed, such as oil and gas, construction, and plumbing.

Weldless connections typically use a mechanical method to join pipes. This could involve a clamp-like device that secures the pipes together, or a swage fitting that is mechanically deformed to secure the pipe. These methods can provide a strong, leak-proof connection without the need for welding

Weldless connections can be quicker to install, safer (as they don’t require hot work and the associated fire risks), and less labor-intensive than traditional welding methods. They also don’t require special site services or permits that might be needed for hot work.

When properly installed, weldless connections can provide a secure, leak-proof seal that is comparable and often better in strength to a welded connections.

Many types of weldless connections can be used with a variety of pipe materials, including steel, copper, and plastic. However, the suitability can depend on the specific product and the manufacturer’s recommendations.

Weldless connections are used in a variety of industries, including oil and gas, plumbing, construction, and manufacturing. They can be particularly useful in situations where quick, safe pipe connections are needed, such as in field repairs or modifications.

After the three seconds are up, the metals are fused together. And the bond is so strong, it becomes stronger than either of the two metals involved in the bonding process.

Because they don’t involve hot work, weldless connections can be safer to install than welded connections. However, as with any mechanical work, appropriate safety precautions should still be taken, including using the correct tools and personal protective equipment.

98% of the studs we put down use a 304 stainless steel, which creates an incredibly strong bond that is immune to the elements. A standard polymer is used to seal the plate against the leak, which fills the pits and helps to planarize if we have to cross a lap joint.
Also, Forge bonding enhances the asset the repair is performed on, which means that the equipment that is repaired is left in better shape than before the leak happened in the first place!

Some types of weldless connections require special tools for installation, such as a hydraulic swage tool. However, these tools are often simpler and safer to use than the equipment needed for welding.

Many weldless connection products are recognized and approved by major standards organizations, but this can depend on the specific application and system conditions.

Weldless connections can often be more cost-effective than welding, particularly for smaller jobs or repairs, due to their speed and ease of installation. Weldless Connections also eliminate the need for hot work permits, hot work planning meetings, and other hot work requirements like fire watch and more.
