The workshop operates as a large-scale production unit, specializing in producing and marketing high-precision, high-strength ERW welded pipes, spiral welded pipes, roller tubes, solar stand tubes, sporting goods tubes, high-precision structural tubes, and piling pipes.
The facility covers a 300,000m² area, with a total investment of over 600 million RMB. Currently, there are 500 staff members, including 50 senior engineers, dedicated to maintaining high-efficiency operations.
The workshop operates four advanced ERW steel pipe production lines, four spiral steel pipe production lines, two 3PE anti-corrosive production lines, one production line for outer plastic and inner epoxy coating, and one insulation steel pipe production line.
Manufacturing processes strictly comply with international standards: API 5L, API 5CT, ASTM A53, ASTM A252, EN10217, EN10219, BS1387, DIN30670, DIN30678, CSAZ245.20, CSAZ245.21, GB/T9711, GB/T3091, GB/T13793, GB/T23257, SY/T0315, SY/T0422, SY/T0457.
Applications: Products are widely utilized in transportation pipelines for oil, gas, coal gas, heating supply, drainage engineering, electricity, chemicals, and are also suitable for piling, structural projects, ocean engineering, machinery, mines, sports equipment, and the automobile industry.
Quality serves as the cornerstone of survival and development. Fully equipped independent testing labs, including physical and chemical laboratories, are utilized to carry out precise evaluations. Testing procedures employ advanced inspection systems such as:
Skilled personnel monitor each step, from testing raw materials to evaluating finished products. The strict implementation of quality control guarantees 100% acceptance for all outgoing shipments. A comprehensive quality-tracking system is maintained to assure long-term product reliability.
