WALFORM sealing ring is one of three parts of WALFORM tube end forming technology. What is WALFORM tube end forming technology, and what are the advantage of it when it compares to the traditional pipe connection technology?
Traditional pipe connection tecnology
The traditional pipe connection technology uses the welding method for hard pipe connection. This connection technology has the disadvantages of large workload, long time consumption, poor stability, easy corrosion, poor pipeline cleanliness, etc. For ships and drilling platforms in working condition, it is often impossible to re weld pipe joints to eliminate faults. The non welding pipeline connection technology can overcome these shortcomings and achieve simple and reliable pipeline connection. The pipes using this technology are easy to disassemble and have reliable performance. The requirements for management and installation technicians are relatively low, and they are well received by shipyards and shipowners.
It can be seen that the implementation of non welding pipeline connection technology not only improves the construction conditions, reduces the operation difficulty, but also reduces the environmental pollution caused by welding, achieves the effect of energy saving and emission reduction, and has good economic and social benefits.
New WALFORM tube end forming technology
The common non welding technologies mainly include flared pipe connection technology, ferrule pipe connection technology, etc. As a new type of pipe connection, WALFORM pipe end forming technology is known as the best leakage prevention scheme at present. WALFORM technology consists of only three parts: 24 ° cone joint body, nut and sealing ring. The traditional DIN standard connector and DIN standard nut are used to connect the formed pipe end, and the sealing ring is installed on the only possible leakage path. The connector body standard fully complies with DIN2353 and ISO8434-1 standards. It has the characteristics of high nominal pressure rating, absolute leak proof, reliable pipe fixation, fast assembly, high dynamic bearing capacity, etc. Through the special steel pipe forming equipment, the steel pipe is cold extruded and reshaped to make the deformation of the steel pipe uniform, convenient for quality control, and free of pitting and cracks.
