stainless steel shower straw

The oil and gas pipeline (API standard), which requires high requirements, has been used almost 100% in the past.Expanding information:When the welded pipe is used as a conveying fluid pipe, it has different requirements from ordinary steel pipes:1. In addition, the circular section is subjected to a relatively uniform force when subjected to internal or external radial pressure, and therefore, most of the steel pipes are round pipes.The 8163 fluid pipe is a seamless steel pipe for fluid transportation (GB/T8163-2008) and is a general seamless steel pipe for conveying fluids such as water, oil and gas.The fluid tube must have a hollow section, but it can also be square, triangular or any other shape. In the past, fluid pipes have traditionally used seamless steel pipes. . Fluid tubes need to remove internal burrs to reduce fluid transport resistance., and have been widely used in steel pipes. are all made of steel pipes. More than 95% of developed countries in Japan and Europe have been replaced by welded pipes.Because of its low cost and high strength, steel pipes are widely used in fluid transportation in modern society. According to its production process, steel pipes are divided into two categories: seamless steel pipes and welded pipes. Some equipment is limited by conditions, and rectangular tubes must be used, but most of them use round tubes. For welded pipes requiring APIs, it is also required to perform ultrasonic testing and hydrostatic testing on the welds of each welded pipe;2. The steel pipe has a hollow section and is used as a pipe for conveying fluid, such as oil, natural gas, gas, water, and some solid materials. The welded pipe has the advantages of better uniformity than the seamless pipe wall, high precision, low energy consumption and high production efficiency. With the development of materials science, molding processes, and unit equipment, welded pipes have been greatly developed. Shelf and steel scaffolding used in construction. It is an economical section steel and is widely used in the manufacture of structural parts and mechanical parts, such as oil drill pipes, automobile transmission shafts, bicycles. Steel pipes are also indispensable materials for various conventional weapons, and barrels, barrels, etc. The weld is not allowed to leak. Since the area of the circle is the largest under the condition of equal circumference, more fluid can be transported by the circular tube. For the transportation of corrosive chemical solutions, all steel pipes must be treated with anti-corrosion treatment of the inner wall;3. Compared with solid steel such as round steel, the steel pipe is lighter in weight when it has the same bending and torsional strength. The welded pipes are divided into high-frequency straight seam welded pipes (ERW), spiral welded pipes (SSAW) and submerged arc welded pipes (UOE).The stainless steel shower safety handle 8163 fluid tube is a hollow section with no welds from start to finish. The use of steel pipes to manufacture ring-shaped parts can improve material utilization, simplify manufacturing processes, save materials and processing man-hours, such as rolling bearing rings, jack sleeves, etc. Steel pipes can be divided into round pipes and shaped pipes according to the shape of the cross-sectional area
