Domestic thin wall spiral pipe is a new type of pipe material, in the late 1990 s to launch thin wall spiral steel tube wall thickness is 6-8 mm stainless steel belt or stainless steel plate, with automatic argon arc welding welding technology made of steel tubes, etc. Due to its safety and health, high strength, good corrosion resistance, durability, long service life, maintenance free, beautiful and other characteristics, has been widely used in building water supply and direct drinking water pipeline.

Along with our country the implementation of the reform and opening up policy, the national economy to obtain rapid growth, urban housing, public buildings and tourist facilities built in great quantities, to the hot water supply and water supply is put forward new requirements. Water quality problems, in particular, people pay more and more attention to, also enhances unceasingly.

Thin wall spiral pipe has the following outstanding advantages: excellent mechanical properties and superior wear resistance performance, safety and health performance is good, good heat resistance performance, heat preservation performance is good, the lining of smooth water resistance; Appearance beautiful, clean, fashion, 100% can be recycled; Which saves water resources; Use range is extensive; The service life is long low comprehensive cost.

At present in the field of thin-walled stainless steel water pipes, pipe fittings and related products is the main difference between the different way of connection, so here are two common thin-walled stainless steel water pipes, pipe fittings connection mode: one kind is convex type connection, one kind is the viega profi-press connection.

On the detailed introduction of connection mode is as follows: card convex type connection method belongs to a way of improvement of compression type connection technology. Whose character is: with special flaring tool position on the thin wall spiral pipe end, from the inside to the outside (radial) roller pressure make the tube to form a flange ring, then the cone tube inserted into a socket of ptfe sealing ring and lock nut pipe fittings, twist lock nut, by advancing compression cone flange ring shape ptfe seals and sealing role. The pipe design and past galvanized pipe fittings design principle, greatly avoid the cumbersome process on the engineering design, budget, construction, more conducive to the popularization and application. Viega profi-press connections: with seal socket pipes connection pipe, pressure pipe with specialized tools and plays a role of sealing and fastening a connection.
