Our Advantages

Three-roll pipe mill
The rectangular seamless steel pipe produced by the three-roll mill for hot-rolling seamless steel pipe has high precision. Because of the cross-rolling with the mandrel, the rolling action is repeated many times in one pass, which greatly improves the accuracy of the wall thickness and is not easy to produce. Defects such as scratches, ears, and green lines; the flexibility in production is large, and the pass size can be changed with the help of the clutch of the roll.

Adequate inventory
Standing inventory of carbon Rectangular seamless tubes, seamless special-shaped tubes, alloy seamless tubes, precision tubes. Various types of seamless steel pipes with a specification of 5-426*0.5-60mm and a length of 2-16m. The cold-rolled precision bright tubes produced by our factory have smooth appearance, uniform wall thickness, no oxide layer, and high precision. The inner hole of the steel pipe can be divided into round type, spline type, plum blossom type, etc. It is widely used in automobiles, motorcycles, electric power, petrochemicals, ships, aerospace, bearings, pneumatic components, oil cylinders, boiler equipment, medical equipment, fitness equipment and other industries.

Attention to detail
No matter how to choose the Rectangular seamless steel pipe, its quality cannot be ignored. It must be noted that there should be no defects on the surface, such as small cracks or scars, etc., and that the thickness of the pipe wall is the same to ensure uniformity. The physical comparison is still very important. Only after the basic comparison of the physical objects is done, can the steel pipes that meet the needs be selected. The processing technology of each seamless steel pipe is different, which will also affect its application field. Now it is generally processed by cold drawing and hot rolling, and the processing effect of the two and the application of steel pipes will also have certain differences.

Applicable scene
Rectangular seamless steel pipes are mainly used in engineering construction, glass curtain walls, door and window decoration, steel structures, guardrails, machinery manufacturing, automobile manufacturing, home appliance manufacturing, shipbuilding, container manufacturing, electric power, agricultural construction, agricultural greenhouses, bicycle racks, motorcycle racks, Shelves, fitness equipment, leisure and tourism products, steel furniture, various specifications of oil casing, oil pipes and line pipes, water, gas, sewage, air, heating and other fluid transportation, fire protection and support, construction industry and other fields.

Quality first: production and inspection in strict accordance with production standards;
Price advantage: discounts based on real market prices;
Transaction security: There will be no loss of customer funds;
After-sales guarantee: the customer's problem is our problem;
Long-term cooperation: quality assurance, price advantage, sincere service can last for a long time.
