Improvement of the Stainless Steel Elbow Pressing Process
Stainless steel elbows are widely used in petrochemical, instrumentation, food, and other industries because of their good corrosion resistance. For professional pipe fittings manufacturers, stainless steel elbows are a high-value-added product, and their quality and output di...Read more -
Technical method for deformation detection of oil and gas steel pipelines
First, the development direction of steel pipeline inspection technology. During the operation of long-distance oil and gas steel pipelines, they are usually corroded from both internal and external environments. Internal corrosion is mainly caused by the combined action of th...Read more -
The seamless characteristics of ERW steel pipe
The biggest difference between electric resistance welding (Electric Resistance Welding, ERW for short) and seamless steel pipe is that ERW has a weld seam, which is also the key to the quality of ERW steel pipe. Modern ERW steel pipe production technology and equipment, due t...Read more -
Specifications and uses of oil casing
Application of oil casing: Oil casing is a kind of seamless steel pipe and an important piece of equipment for oil drilling. Its main equipment also includes drill pipe, core pipe and casing, drill collar, and steel pipe for small-diameter drilling. The domestic casing is made...Read more -
Annealing, normalizing, quenching, and tempering of steel pipes
Annealing of steel pipe: Heating the steel pipe to a certain temperature and keeping it warm for some time, and then cooling it slowly is called annealing. The annealing of steel pipe is a heat treatment method in which the steel pipe is heated to the temperature at which phas...Read more -
What are the classifications of spiral steel pipe welded pipes
Welded steel pipe, also known as welded pipe, is a steel pipe made of steel plate or steel strip after crimping and welding. Welded steel pipe has a simple production process, high production efficiency, many varieties and specifications, and less equipment investment, but its...Read more -
Seamless steel pipe for hydraulic cylinder
Seamless steel pipes for hydraulic cylinders are seamless steel pipe products used in hydraulic cylinders. Hydraulic cylinders can be divided into piston cylinders, plunger cylinders, and swing cylinders in the structure. Cylinders can be divided into piston cylinders, film cy...Read more -
Four quality inspections of stainless steel elbow welding
1. Appearance inspection: Generally, it is mainly observed with the naked eye, sometimes with a magnifying glass 5-20 times. Through visual inspection, surface defects of welded stainless steel elbow welds can be found, such as undercuts, welding tumors, surface cracks, pores,...Read more -
Alloy steel pipe details
The performance of alloy steel pipe is much higher than that of ordinary seamless steel pipe. (1) Raw materials are strip steel coils, welding wires, and fluxes. Before putting into use, they must go through strict physical and chemical tests. (2) The head-to-tail butt joint o...Read more
