Carbon Steel Pipe Seamless Steel Pipes Suppliers and Manufacturers

Spiral welded pipe(SSAW pipe, also called HSAW pipe). The pipe is formed by spiral submerged arc welding technology. Spiral welded pipes are formed using narrower plates or hot rolled coils, which lowers their production costs significantly. The welding line is shaped like a helix. The spiral welding process permits the production of large-diameter pipes suitable for transporting large volumes of oil and gas. Some SSAW pipes were historically limited to low-pressure applications.

Welded steel pipe, like common ERW steel pipe, cannot ignore the trouble about cutting. And this is an essential step for the whole tubeâ??s production process. For manufacturers, they have to pay attention to that as a poor cut can lead to poor fit-up steel pipe. What effects are when there is poor cut. In general, a poor cut can lead to poor fit-up and create unnecessary gaps. More over, for some special steel tube, like stainless steel pipe with corrosion-resistant pipe, this would lead to distortion which may affect the corrosion-resistant quality. Of course, poor preparation also leads to longer weld cycle times, higher consumable costs and potential repairs. Thus, it would have influence for a pipeâ??s quality. How to solve this trouble for welders? A necessary cutting equipment would be the first step. For example, buying dedicated orbital pipe cutting equipment to guarantee cuts within mere thousandths of an inch of the specified parameters maybe one of the steps. Of course, the skilled experience for welder is also important.

Steel pipes

We choose a kind of steel pipe due to its practical function. No matter seamless steel pipe or welded one, its features would finally determine its work environment. Today, we would like to discuss about the elements increasing hardness of abrasion resistant steel pipe. What makes abrasion resistant steel more immune to wear than other types of steel? And how we guarantee its quality when used in tubes? The chemical composition of abrasion resistant steel would give us answers. Some alloys would increase the ability of abrasion resistance. For example, carbon will help block dislocations, thus, it will enhance the hardness and strength of a steel pipe. The added carbon also allows the steel to form microstructures with increased hardness when heated and quenched. There are other elements that can be added to abrasion resistant steel to increase its hardness value too. Chromium and manganese are also added to abrasion resistant steels to help reduce the negative effects caused by wear.

The hot expanded seamless steel pipe is relatively low density but the contraction of the strong seamless steel pipe can be referred to as thermal expansion. The roughing finishing process for expanding the diameter of a pipe by a cross-rolling method or a drawing method. Steel pipe thickening in a short period can produce non-standard and special types of seamless tubes with low-cost and high production efficiency, the current international developments in the field of tube rolling.

Seamless steel pipe is hollow section, a large number of used for conveying fluid pipe, such as oil, natural gas, coal gas, water and some solid materials, such as pipelines. Compared to the steel pipe and round steel solid steel bending torsional strength phase at the same time, the weight is lighter, is a kind of economic cross section steel, widely used in the manufacture of structural and mechanical parts, such as petroleum drill pipe, auto transmission shaft, bicycle frame and construction of steel scaffolding is used with steel pipe manufacturing annular parts, such as can improve material utilization, simplifying the manufacturing process, material saving and processing time, has been widely used to make steel pipe. carbon steel seamless pipe wholesale: Cangzhou Weiheng Pipe Industry Co., Ltd.
