  What is ASME B36.10 Schedule 80 Carbon Steel Pipe?

  ASME B36.10 is a widely recognized American Society of Mechanical Engineers (ASME) standard that covers the dimensions of welded and seamless wrought steel pipes. It provides the standard nominal pipe sizes (NPS), outside diameters (OD), wall thicknesses, and related dimensional specifications for carbon steel pipes used in pressure and non-pressure applications.The goal of ASME B36.10 is to create uniformity and compatibility in pipe manufacturing and application, ensuring that pipes from different manufacturers can be interchanged and fit correctly in piping systems.

  Comprehensive Guide to API 5L LSAW Steel Pipes

  In modern pipeline engineering, API 5L LSAW steel pipe is an indispensable material. It is not only strong and durable, but also designed to cope with high-intensity and high-pressure environments such as oil and natural gas transportation and urban water supply. LSAW means "longitudinal double-sided submerged arc welding". This welding method ensures that the weld of the steel pipe is uniform and dense, can operate stably for a long time, and is not prone to leakage or rupture. In addition, this type of steel pipe also complies with the API 5L international standard, which means that its material, size, tolerance and performance have been strictly tested and can be safely used in various key projects, such as inter-provincial oil pipelines, natural gas trunk lines, water supply channels at water sources, etc.

  LSAW Steel Pipe Forming UOE vs JCOE Methods Explained

  The straight seam submerged arc welded steel pipes (LSAW Pipe) for oil pipeline engineering are generally manufactured by UOE and JCOE. The conventional production process is that after the steel pipe blank is formed by UO or JCO, it is pre-welded, internal and external final welded, expanded, non-destructive tested, pipe end processed, hydraulic pressure tested, weighed and measured, and visually inspected for steel pipe markings. Let's learn about the characteristics of the two processes of UOE and JCOE today!

  How to Maintain Stainless Steel Structural Pipe?

  Stainless steel structural pipes are strong and durable, not easy to rust, and look very textured, so they are often used in construction, machinery, food processing and other industries. However, no matter how good the material is, it is not omnipotent. If it is neglected for a long time, its surface may become dark, spotted, or even corroded. If you want it to keep its brightness, stable performance, and last longer, daily cleaning and maintenance are very important. Whether you use it indoors or outdoors in the wind and sun, this easy-to-understand maintenance guide can help you easily handle the daily maintenance of stainless steel structural pipes.

  How to Weld Stainless Steel with TIG MIG or Flux Core

  Stainless steel welding rods can be divided into chromium stainless steel welding rods and chromium-nickel stainless steel welding rods. All the welding rods that meet the national standard of these two types shall be assessed according to the provisions of the national standard GB/T 983-2012. Chromium stainless steel has certain corrosion resistance (oxidizing acid, organic acid, cavitation), heat resistance and corrosion resistance. It is usually selected as equipment materials for power stations, chemical industry, petroleum, etc. However, chromium stainless steel generally has poor weldability, and attention should be paid to welding process, heat treatment conditions and selection of suitable welding rods. Chromium-nickel stainless steel welding rods have good corrosion resistance and oxidation resistance, and are widely used in chemical industry, fertilizer, petroleum, and medical machinery manufacturing. In order to prevent intergranular corrosion caused by heating, the welding current should not be too large, about 20% less than that of carbon steel welding rods, the arc should not be too long, the interlayer should be cooled quickly, and a narrow weld is preferred.
