Quality Assurance
"Quality is the cornerstone of business survival, is the soul of brand casting." We have independent testing labs such as physical labs, chemical lab and advanced inspection equipment such as X-ray imaging system, magnetic detectors, offline UT equipment, steel pipe whole body UT equipment and hydraulic testing machine.
Our products are widely used in transportation pipeline for oil and gas, coal gas, heating supply, drainage engineering, electricity and chemical; and also used for piling, structure, ocean engineering, machinery, mine, sports, automobile and many other industries.
ERW Pipe Producing Equipment
Excellent production equipment, processed Ф89, Ф140, Ф168, Ф273mm, four ERW welded pipe production line and 600mm, 1500mm, 1800mm three longitudinal shear line. The Size range is OD: Ф33.4mm to Ф273mm, thickness 3mm to 14mm. To ensure the development of steel pipe with special specification, we actively enlarge the investment in the equipment, in return for customer's long-term.
Spiral Welded Pipe Producing Equipment
Four advanced double-side spiral submerged ARC welded steel pipe production lines, producing OD: Ф219mm-3000mm, thickness 5mm-30mm, Grade X80 double-side spiral submerged Arc welded pipe, not only with high deposition rate but also have anatexis ability, quality welded seam, pretty compactness, the appearance of welded seam is flat and smooth which can satisfy different demand on seam.
