Large-diameter straight seam submerged arc welded steel pipe

The main issue in producing large-diameter straight seam rolled pipes is welding. As long as they can pass the non-destructive testing, the delivery requirements are relatively broad compared to other products.

Large-diameter straight seam submerged arc welded steel pipe

The main detection method for large-diameter straight seam rolled pipes is ultrasonic flaw detector, and the longitudinal welds on the same section of the rolled pipe should not exceed two.

Thick-walled tapered steel pipe

Cone tube, also known as cone tube, is a hollow cone tube made from sheet or pipe material and produced through thermal expansion or rolling processes with different diameters at both ends.

Thick-walled tapered steel pipe

The tapered steel pipe has an outer diameter ranging from 60mm to 450mm, with a thickness of 6mm to 40mm and a length of 8 meters. Cone shaped steel pipes are mostly customized for processing, so if customers need to indicate the large head diameter, small head diameter, thickness, length, material, and quantity.

Half circle coiled tube

Using solvents and emulsions to clean the surface of steel to remove oil, grease, dust, lubricants, and similar useful substances, but it cannot remove rust, oxide scale, welding flux, etc. on the surface of steel, so it is only used as an auxiliary means in stable performance production.

0235B semi-circular steel pipe

The function of rust proof oil for thick walled coiled pipes is to prevent rust, which can make the thick walled coiled pipes smooth and new for a long time, reducing external corrosion on them.

Semi-circular pipe

The shape of the semi-circular tube is like cutting a steel pipe into two halves with a wire, forming two and a half circles. The manufacturing method is to roll the steel strip with a rolling mill. The purpose is to be used on the outside of steel pipes for anti-wear purposes.

Special-shaped pipes

Excellent mechanical performance: Due to its different cross-sectional shape from conventional circular steel pipes, special-shaped pipes have better load-bearing capacity and strength.
