Company introduction

Qingdao Wuxiao Group pipe making subsidiary is the largest professional manufacturer of steel pipes in China currently, covers an area of 50,000 square meters and employs more than 300 staff.

Our main products includes large-diameter straight-seam thick-walled steel pipes for various purposes, high-voltage transmission pipes, all types of substation towers, large TV towers and large span steel structures, total annual production capacity can reach 600,000 tons.

The company has introduced Germany pipe making technology and process equipment, and owns the production line of longitudinal welded pipes with the thickest wall and largest diameter in China at the moment. We have equipment such as CNC plasma flame cutting machine, large CNC bending machine, auto stitching machine, inner and outer auto welding machine, finishing and round adjusting machine, straightening machine and so on, well-equipped, huge scale, which greatly improved our production efficiency. In the same time, we had introduced lots of inspection equipment, such as digital ultrasonic flaw detector, X-ray flaw detector, impact testing machine etc., laid solid foundation for company to complete projects with quality and quantity guaranteed.

Available specifications for steel pipes include: pipes made of various materials with a length of 12,300mm, diameter of 406 to 2,600mm, and wall thickness of 100mm below.

The welding seam adopts multi-wire double side automatic submerged arc welding, which ensures the production efficiency, quality of welding seams and the quality of steel pipe molding.

Our equipment has the advantages of producing LSAW with long length, thick wall and large diameter, and then can effectively reduce the presence of circular welding seams in structural steel pipes.

We return every customer with enthusiastic attitude, excellent quality and considerate services. Adhering to the service tenet of "making customers more satisfied", the company sincerely welcomes friends from all over the world for visit, idea-exchange and cooperation!


Our welded carbon steel pipe products are widely used in pressure piping convey, steel structural usage, processing, ocean engineering, vessel building and offshore platform etc. Pipe we produced, max length:12300mm; dia range: 406-2600mm; max wall thickness: 100mm. submerge welding can guarantee the welding quality.
