Wide opening spiral pipe is also called wide opening spiral steel pipe or wide opening spiral welded pipe. It is made by rolling the steel strip of low carbon structural steel or low alloy structural steel into a blank according to the Angle of a certain wide opening spiral pipe (called forming Angle) and then welding the joint. It can produce large diameter steel pipe with narrow strip steel.Common standards for wide opening spiral pipes are generally classified as SY/T5037-2000, GB/T9711.1-1997, API-5L and SY/T5040-92.The wide opening spiral pipe for conveying confined fluid is mainly used for pipelines conveying oil and natural gas. The pipe has strong bearing capacity and good plasticity, which is convenient for welding and processing.The wide opening spiral pipe for general low-pressure fluid transportation is made by double-side automatic submerged arc welding or single-side welding. It is used for water, gas, air, steam and other general low-pressure fluid transportation.The outside diameter of the helix pipe distributed by the company is ￠219-2420mm and the wall thickness is 5-32mm. The material of the helix pipe is Q235A,Q235B,OCr13,1Cr17, etc.
