We all know that stainless steel seamless steel pipes generally undergo some special treatments when they leave the factory to make the surface look bright and there will be no rust, but when we use it for a long time, coupled with environmental and other factors, There will still be some rust, so how do we clean the rust of stainless steel seamless steel pipes? After the production of...

The method of using an acid solution to remove oxide scale and rust on the surface of the steel is called pickling. Iron oxides such as scale and rust react chemically with the acid solution to form salts which are dissolved in the acid solution and removed. Acids for pickling include sulfuric acid, hydrochloric acid, phosphoric acid, nitric acid and mixed acids. The dipping and pickling method...

Nickel-based alloys are generally alloyed with Ni content exceeding 30wt%, and the Ni content of common products exceeds 50wt%. Nickel alloy seamless pipe and tube are seamless pipes produced from nickel-based alloys. Due to its superior high-temperature mechanical strength and corrosion resistance, it is called Superalloy together with iron-based and cobalt-based alloys. It is generally...

Intergranular corrosion is common localized corrosion, which extends to the inside along the interface between metal grains. The mechanism of intergranular corrosion mainly includes "Cr-poor theory" and "Selective dissolution theory of grain boundary impurities". Poor Cr theory The saturated solubility of C in austenite is less than 0.02%. Generally, the C content of stainless steel is higher...

Usually, according to the use of steel pipe and its working conditions, different technical conditions should be proposed for the allowable deviation of steel pipe size, surface quality, chemical composition, mechanical properties, process performance and other special properties. When general seamless steel pipes are used to transport water, gas, oil and other fluid pipes and to manufacture...

When we are decorating, we can see all kinds of building materials, among which there may be austenitic stainless steel seamless pipe. So what is the performance of Austenitic Stainless Steel Seamless Pipe ? Austenitic stainless steel seamless pipe is resistant to corrosion by oxidizing acid media. If it contains elements such as Mo and Cu, it can also be resistant to corrosion by sulfuric...

The definition of Austenitic Stainless Steel Seamless Tube is the smelting and manufacturing of stainless steel in which the ferrite phase and the austenite phase in its solid-quenched structure are each half. The austenitic stainless steel seamless tube material has excellent mechanical properties, corrosion resistance, and good weldability, and has a wide range of uses in the oil and gas...

We can see Alloy Steel Seamless Pipe in many places, including various factories. Today, let’s talk about what Alloy Steel Seamless Pipe is. Alloy Steel Seamless Pipe has a long strip of steel with a hollow section and no joints on the periphery. Steel pipes have a hollow section and are used in large quantities as pipelines for conveying fluids, such as pipelines for conveying oil,...

Alloy Steel Seamless Pipe is a kind of seamless steel pipe, and its performance is much higher than that of ordinary seamless steel pipe. Alloy Steel Seamless Pipe contains elements such as silicon, manganese, chromium, nickel, molybdenum, tungsten, vanadium, titanium, niobium, zirconium, cobalt, aluminum, copper, boron, and rare piles of earth. Alloy Steel Seamless Pipe is a kind of...
