Application of the Spiral Steel TubesFebruary 24, 2017
Domestic thin wall spiral pipe is a brand-new kind of pipeline material, in the late 1990 s to launch thin wall spiral steel tube wall density is 6-8 mm stainless steel belt or stainless steel plate, with automatic argon arc welding technology made of steel tubes, and so on. Due to its security and health, high strength, great rust resistance, durability, long service life, maintenance totally free, gorgeous and other characteristics, has been extensively used in structure supply of water and direct drinking water pipeline.
Together with our nation the execution of the reform and opening up policy, the nationwide economy to obtain quick development, metropolitan housing, public buildings and traveler facilities integrated in muches, to the hot water supply and supply of water is advanced brand-new requirements. Water quality issues, in particular, people pay a growing number of focus on, likewise boosts unceasingly.
Thin wall spiral pipe has the following outstanding advantages: exceptional mechanical residential or commercial properties and exceptional wear resistance performance, safety and health efficiency is good, great heat resistance efficiency, heat conservation performance readies, the lining of smooth water resistance; Appearance stunning, clean, fashion, 100% can be recycled; Which conserves water resources; Use range is comprehensive; The service life is long low extensive expense.
At present in the field of thin-walled stainless-steel water pipes, pipe fittings and related products is the main difference between the different method of connection, so here are 2 typical thin-walled stainless steel pipes, pipeline fittings connection mode: one kind is convex type connection, one kind is the viega profi-press connection.
On the in-depth intro of connection mode is as follows: card convex type connection approach belongs to a method of improvement of compression type connection innovation. Whose character is: with unique flaring tool position on the thin wall spiral pipe end, from the inside to the outside (radial) roller pressure make television to form a flange ring, then the cone tube inserted into a socket of ptfe sealing ring and lock nut pipeline fittings, twist lock nut, by advancing compression cone flange ring shape ptfe seals and sealing role. The pipeline design and past galvanized pipe fittings design principle, significantly prevent the troublesome procedure on the engineering style, budget plan, construction, more conducive to the popularization and application. Viega profi-press connections: with seal socket pipes connection pipe, pressure pipeline with specialized tools and contributes of sealing and attaching a connection.
