Yanshan Yonghui Steel Pipe Co., Ltd. was established in 2003, located in Wuliyao Industry Zone of Yanshan North Circle. We are a specialized company in producing tubes.
Our company manufactures and sells products of Baotou Steel Plant, Chengdu Steel Plant, Anshan Steel Plant and Tianjin Steel Plant. There are large caliber hot broadened seamless tubes, double submerge-arc welded spiral tubes, special medium seamless tubes, API seamless toughened tubes, welded tubes and galvanized tubes.
The hot-rolled tubes and API seamless toughened steel tubes are for wholesale, with invisible welded lines. The hydraulic test grade is 5MPA-30MPA (30 to 50 times by ordinary welded tubes). Our company has gained deed of appropriation of API5I member symbol of American Oil Academy and passed ISO9002 quality system attestation of Norwegian Ships Classification Organization.
Our products have been successfully applied instead of seamless tubes in many fields, widely used in important liquid transferring and steel projects, such as oil, chemistry, natural gas, city coal gas, mine, traffic, construction, water and fire. Each of them will be tested before leaving factory. We can manufacture tubes which are nonstandard and have different wall thicknesses according to customers' requirements.
Our company has newly introduced two large seamless tube hot broadening production lines so that we can produce seamless tubes which have outsized wall thickness. We can process with customers' materials and also can produce nonstandard seamless tubes.
