Welded pipes have a wide range of applications in various industries and fields. Whether in the oil and gas industry, chemical industry, construction industry, or other industrial fields, welded pipe is a common choice. This is because welded pipes have many c......

Radiographic Testing (RT), also known as industrial radiography, is a critical discipline in the field of nondestructive testing. Its primary application is to detect macroscopic geometric defects within workpieces. Depending on specific characteristics, RT ca......

The welded pipe production process is a complex blend of technology and technical expertise that transforms raw materials into high-quality steel pipes. This guide explores the process, from raw material preparation, specific welding methods, including Plasma ......

Stainless steel pipes can be classified into two types: seamless pipes and welded pipes. Seamless pipes are produced by cold drawing or cold rolling, with high dimensional accuracy and surface quality, suitable for high-demand applications such as petrochemica......

Metal corrosion problems are widespread in many areas of the national economy, such as oil and gas, petrochemical, transportation, machinery manufacturing, etc. It can be said that corrosion problems exist wherever metal materials are used. Metal materials ar......

The mechanical properties of capillary metal materials refer to the behavior of metal materials under external loading or under the combined action of load and environmental factors (temperature, medium and loading rate). Common metal mechanical properties ar......

SiliconThe content of silicon in austenitic stainless steel is generally below 0.8% - 1.0%. As an alloy element, silicon content ranges from 2% to 7% depending on its use. Silicon is an element that strongly forms ferrite. In austenitic stainless steel, with t......

MolybdenumThe ability of molybdenum to form ferrite is comparable to that of chromium. Molybdenum also promotes intermetallic compounds in stainless steels. In order to maintain a single austenite structure in austenitic stainless steel, the content of nickel,......

CarbonCarbon in austenitic stainless steel is an element that strongly stabilizes austenite and expands the austenite zone. The carbon gap is dissolved in austenite, and the strength of austenite can be significantly improved through solution strengthening. Ho......

Stainless steel wire is a kind of silk products with different specifications and models made of stainless steel. The common stainless steel wires with good corrosion resistance and high cost performance are 304 and 316 stainless steel wires.The types of stain......

Recently, due to the 8-month Russia-Ukraine conflict and the coming winter, the European energy crisis has been intensifying. Natural gas prices in many places have reached record highs, and LNG ship freight rates have continued to rise. Experts say the situat......

Rockwell hardnessUse diamond cone or quenched steel ball indenter to press the indenter into the material surface under the action of test pressure F. After holding for a specified time, remove the main test force and maintain the initial test force. Calculate......

1.304 stainless steel. It is one of the most widely used austenitic stainless steels with a large amount of applications. It is suitable for manufacturing deep drawing formed parts, acid transmission pipes, vessels, structural parts, various instrument bodies,......

There are three main factors affecting stainless steel corrosion:1. The content of alloying elements. Generally speaking, steel with a chromium content of 10.5% is not easy to rust. The higher the content of chromium and nickel, the better the corrosion resis......

Nickel Alloy 625 is a face centered cubic crystal structure. After holding at 650 ℃ for a long enough time, carbon particles and unstable quaternary phase will be precipitated and transformed into stable Ni3 (Nb, Ti) orthorhombic lattice phase. After solution......

UNS N06600 is corrosion resistant to a wide range of corrosive media. The chromium composition gives the alloy better corrosion resistance under oxidizing conditions than nickel 99.2 (alloy 200) and nickel 99.2 (alloy 201, low carbon). Also, the higher nickel ......

Last week, MT Group held the annual mid-year meeting. 2022 is also a year full of changes and challenges for Mtsco. In the first half of the year, we changed our new office environment, held a business PK competition, and participated in Tube Dusseldorf after ......

How much do you know about seamless steel pipe? Seamless steel pipe is a kind of round, square, rectangular steel with hollow cross section and no seam around. Seamless steel pipe is made from ingots or solid billets that are perforated to make a burr pipe ......

Nickel is a ferromagnetic metal element with excellent properties such as corrosion resistance, high temperature resistance, oxidation resistance and good ductility. It is widely used in metallurgy, chemical industry, aerospace and other fields. It is an impor......

1. Folding Fake and inferior welded stainless steel pipes are easy to fold. Folding is a variety of fold lines formed on the surface of stainless steel pipes. This defect often runs through the longitudinal direction of the whole product.The reason for foldin......

Directly welded pipes: the use of small size model can avoid stress corrosion, hot cracks and deformation, and the welding current is 20% lower than that of high carbon steel. In order to ensure the ignition of the electric arc, the DC reverse connection is a......
