Spiral welded pipe is the ratio of the outside diameter and wall thickness of steel tube is less than 20 steel tubes known as spiral welded pipe.It is mainly used as drilling pipe for petroleum geology, cracking pipe for petrochemical industry, boiler pipe, bearing pipe and high-precision structural pipe for automobile, tractor and aviation.
Spiral welded pipe is the most common product in machining at present, so the development of spiral welded pipe is concerned by the majority of traders and end users.Spiral welded pipe is a kind of high price steel products, according to the spiral welded pipe material is divided into two kinds: carbon steel spiral welded pipe and alloy spiral welded pipe.
Carbon steel spiral welded pipe is the largest use of all the products of spiral welded pipe, the classification of carbon steel spiral welded pipe can be divided into 20# and 45# two categories.Welcome customers to our company to order all kinds of carbon steel spiral welded pipe, alloy spiral welded pipe products!
The biggest difference between spiral welded pipe and thin wall steel pipe in steel pipe wall thickness, generally speaking, thin-walled steel pipe cold drawing technology, and the spiral welded pipe generally use hot rolling technology, if unit of measure is used to distinguish, so, it is generally believed that wall thickness/diameter is equal to 0.02 is the watershed spiral welded pipe and thin wall steel tube, wall thickness is thin wall steel tube/pipe diameter less than 0.02, is greater than the spiral welded pipe, on purpose, thin-walled steel tube used in pipeline. Spiral welded pipe is mostly used in blank of hollow parts. Pressure bearing and important piping.
Spiral steel pipe is widely used in natural gas, petroleum, agriculture, chemical industry, electric power, heating, water supply and drainage, steam heating, pressure steel pipe for hydropower station, thermal power generation, water source and other long-distance conveying pipe fittings and piling, dredging, bridge, steel structure and other engineering fields. Can also be used for liquid transport, gas transport and so on.
Because the spiral steel tube is very environmental friendly and competitive among the tubes used, I believe that the spiral steel tube will restore its original glory and create new miracles in the near future.
