The processed spiral steel pipe has greater flexibility in the size and specification range of diameter and wall thickness, especially in the production of high-steel grade thick wall pipe, especially in small and medium-sized thick wall pipe has incomparable advantages, which can meet the user's more requirements in the specification of spiral steel pipe.

Adopting the advanced double-sided submerged arc welding technology, the welding can be realized in the optimal position, and it is not easy to have the defects such as wrong side, deviation and incomplete welding, etc., and easy to control the welding quality.Spiral steel pipe is mainly used in tap water engineering, petrochemical industry, chemical industry, electric power industry, agricultural irrigation, urban construction, is one of the 20 key products developed in China.For liquid transport: water supply, drainage.

For gas transmission: gas, steam, liquefied petroleum gas. For structural use: as pile driving pipe, as bridge; Pipes for wharves, roads, building structures, etc.Our manufacturing is ISO 9001:2008 certified, and our pipes meet API, CE, TUV, ASTM, JIS, EN, DIN, ANSI Standards.
