First, will stainless steel pipe fittings rust? Stainless steel pipe fittings are not easy to rust, but stainless steel pipe fittings will also rust. The fact that stainless steel pipe fittings are not easy to rust has a lot to do with the composition of stainless steel. In addition to iron, stainl

First, can anti-corrosion steel pipes be exposed to rain? The anti-corrosion layer of anti-corrosion steel pipes is waterproof, but excessive rainwater infiltration will have a certain impact on the anti-corrosion layer of anti-corrosion steel pipes. In addition, the better the material and quality

First, will the galvanized steel pipes rust? When the steel pipe is exposed to the air, it will rust when it reacts with oxygen or is corroded by oxygen elements in the water to become oxides. The galvanized steel pipe is galvanized to form a galvanized layer to isolate the air, so it is more corro

In the steel industry, 40Cr alloy steel pipes have won the favor of the market with their excellent mechanical properties and a wide range of application scenarios. First, the chemical composition and manufacturing process of 40Cr alloy steel pipes The main components of 40Cr alloy steel pipes a

Q355 seamless steel pipe is a product that has attracted much attention in the steel industry. Its appearance provides high-quality construction and engineering materials for all walks of life. Q355 seamless steel pipe refers to seamless steel pipes made by a specific process. Its main components ar

With the development of the economy and the advancement of technology, the steel industry has become an indispensable and important part of modern industry. Among them, galvanized steel pipe, as a common steel material, is widely used in construction, bridges, roads, pipelines, petrochemicals, and o

In the complex steel market, seamless stainless steel pipes are widely used in many industries such as petroleum, chemical, medical, and food due to their unique corrosion resistance, high strength, and good processing performance. However, facing a wide range of products, how to accurately select s

Drill pipe corrosion is a common problem in drilling projects, and it is becoming more and more serious as drilling develops towards deep/ultra-deep wells, deep-sea wells, and highly corrosive wells. In drilling operations, to meet the needs of various drilling processes, drilling fluid systems such

1. What is a tempering crack Tempering crack (temper crack) is defined as the shape of the steel that is tempered due to rapid heating, rapid cooling, or phase change. There are two types of tempering cracks: One is the crack that occurs during rapid tempering heating; The other is the crack tha

Pipes for three chemical industries (petroleum cracking, fertilizer, chemical industry pipes) Steel pipes for petroleum, petrochemical, and chemical industries (including the coal chemical industry) are commonly referred to as steel pipes for three chemical industries, generally referring to the pe

1. Steel pipeline corrosion protection generally adopts two common main methods: external coating and cathodic protection. 2. Although most of the surface of the steel pipeline is covered with a coating, a slight leak will cause an incredible corrosion rate, even perforation or cracking. Therefor

First, cooling of steel pipes After the steel pipes are sized, they will be transported to the pre-finishing area through rollers. The first process of the finishing line is cooling, which is carried out on the cooling bed. The cooling beds are chain cooling beds, rack cooling beds, spiral cooling

1. How is decarburization caused Decarburization is a phenomenon that occurs when the oxidation rate of the steel surface is lower than the diffusion rate of carbon. Both oxidation and carbon diffusion occur strongly at high temperatures above the A1 phase transformation point. Decarburization can

1. Concave correction Features: The outer surface of the steel pipe is spirally concave. Causes: 1) Improper adjustment of the straightening machine roller angle and excessive pressure reduction. 2) Severe wear of the straightening roller, etc. Inspection: The outer surface of the steel pipe is

Seamless steel pipe torque is a key physical parameter in the steel pipe industry. It not only directly affects the performance of steel pipes, but also has important applications in various engineering fields. When analyzing the torque of seamless steel pipes, we need to consider multiple factors,

A333Gr.6 seamless steel pipe is an important material widely used in the field of fluid transportation such as oil and natural gas. Its excellent performance and wide application fields make it play an important role in the industry. Below we will introduce the manufacturing process, performance cha

ASTM A53 GR.B seamless steel pipe is a pipe material widely used in fluid transportation systems. It has excellent mechanical properties and corrosion resistance and is widely used in the transportation of oil, natural gas, water, steam, etc. First, the properties of ASTM A53 GR.B seamless steel

Stainless steel seamless pipes are generally treated when leaving the factory, and there will be no rust on the surface. However, when they are used for a long time and in a harsh environment, some rust that is difficult to remove may appear. At this time, it is necessary to perform a "pickling" cle
