The difference between ERW steel pipe and spiral steel pipe

Steel pipes can be seen everywhere in our daily life. It is widely used in heating, water supply, oil and gas and other industrial liquids, which brings great convenience to our life and production. According to the tube forming technology, steel tubes can be roughly divided into the following four categories: seamless steel tubes, high-frequency welded tubes, LSAW tubes, and spiral submerged arc welded tubes. According to the form of the weld we can be divided into seamless steel pipe, ERW steel pipe and spiral steel pipe. We have made a corresponding comparison of ERW steel pipes and spiral steel […]

Carbon Steel pipe Bollards – Steel Pipe Security for Building Perimeters

Why choose steel pipe bollards Steel posts are one of the simplest, most cost-effective ways to offer protection for buildings and pedestrians from vehicle collisions, as both a physical and visual barrier. Steel bollards can be installed in any surface, indoors or outdoors, to prevent entry from errant vehicles, secure vulnerable areas, and protect site assets. As the population, especially in urban centers, continues to grow, so too does the number of vehicles on the road. With the increase of drivers and cars in and around cities, the likelihood of accidents and collisions has gone up as well. Properly planned […]
