Cold extrusion

Process characteristics: WALFORM pipe end forming technology, as a new type of pipe connection, is known as the most advanced anti-leakage solution, replacing the card-type connection. The WALFORM technology consists of only three parts: 24° taper joint body, a nut and a sealing ring. The steel pipe is cold-extruded and reshaped by a proprietary steel pipe forming equipment to make the steel pipe deformation uniform and easy to control the quality without pitting and cracking.

Process advantages: The traditional DIN standard joint and the DIN standard nut are used to join the formed pipe end, and a seal ring is installed on the possible leak path. The body standard is fully compliant with DIN 2353 and ISO 8434-1. It has high nominal pressure level, leakproof, reliable pipe fixing, fast assembly, high dynamic bearing capacity, low torque and safe installation. Simple process, advanced technology， without leakage and can be repeatedly disassembled.
