Serving the steel pipe industry for 20 years

The strength of the steel pipe refers to the maximum ability to resist damage caused by external force or load. Whether it is a straight seam steel pipe or other steel pipes, the strength or strength value is the nature of the material itself. The strength ratio is a main indicator to measure the li

Before installing the steel pipe, the trench needs to be dug, and the soil dug after the trench has a reasonable stacking place, the excavated earth should be transported to the outside in time, and should not be too close to the trench, there must be two The distance above the meter, so as not to a

Steel pipes can be used to transport fluids and powdered solids, exchange thermal energy, and make mechanical parts and containers, it is also an economical steel. For example, the use of steel pipes to make grids, pillars and mechanical supports for building structures can reduce the weight and

The quality of the steel pipe is not only related to its service life, but also related to its use efficiency. Then when we are buying steel pipes, we can roughly distinguish the quality of the steel pipes by the appearance of the steel pipes. If the surface of the steel pipes has numbness and is no

Analysis of the reasons why double-sided submerged arc straight seam steel pipes are widely used:(1) Since it is a straight weld, the weld is short, so the chance of defects is small.(2) The welding seam is a straight line, which has little effect on the coating of anticorrosive materials.(3) There

The inspection and acceptance of straight seam steel pipes shall be carried out by the technical supervision department of the supplier. The supplier needs to ensure that the straight seam steel pipe meets the requirements of the corresponding product standards at the time of delivery. The purch

Straight seam steel pipe expansion is a pressure processing technology that uses hydraulic or mechanical means to apply force from the inner wall of the steel pipe to expand and expand the steel pipe radially outward. The mechanical method is simpler and has a higher speed than the hydraulic met
