What are the removal methods of Duplex stainless steel Pipe?

There are two classifications of stainless steel: one is divided into chrome stainless steel and chrome-nickel stainless steel according to the characteristics of alloy elements; the other is divided into M stainless steel, F stainless steel, and A stainless steel according to the organization state of the steel in the normalized state.A-F duplex stainless steel.

Duplex Stainless Steel Pipe has good welding performance. Compared with ferritic stainless steel and austenitic stainless steel, it is not like the heat-affected zone of ferritic stainless steel. Due to the severe coarsening of grains, the plastic toughness is greatly reduced. It is not as sensitive to welding hot cracks as austenitic stainless steel.
Due to its special advantages, duplex stainless steel is widely used in petrochemical equipment, seawater and wastewater treatment equipment, oil and gas pipelines, papermaking machinery and other industrial fields. In recent years, it has also been studied in the field of bridge load-bearing structures. Prospects.
Duplex stainless steel has a ferrite phase and an austenite phase each in its solidified structure, and the content of the minimum phase may generally reach 30%.
As a Seamless Stainless Steel Tubing Supplier, I would like to share with you the safety restrictions and requirements of Duplex stainless steel Pipe.
When selecting duplex stainless steel in different corrosive environments, it should be noted that the corrosion resistance of steel is always relative. Although duplex stainless steel has good local corrosion resistance, as for duplex stainless steel, he also has an applicable range of media conditions, including temperature, pressure, media concentration, and pH needs to be carefully selected. Many of the data obtained from the literature and manuals are the results of laboratory corrosion tests, which are often different from the actual conditions of the project. Therefore, it is necessary to pay attention to the selection of materials, and if necessary, to perform corrosion tests in actual media or under field conditions. Hanging test, even the test of the simulation device.
What are the removal methods of the duplex stainless steel Pipe scale?
The stainless steel small pipe spraying (polishing) derusting is driven by the high-power motor to rotate the spraying blades at high speed, so that the abrasives such as steel grit, steel shot, wire segment, minerals, etc. are sprayed (polished) on the surface of the stainless steel square tube under the effect of centrifugal force Not only can completely remove rust, oxides and dirt, but also the stainless steel square tube can achieve the required uniform roughness under the effect of the strong impact and friction of the abrasive.
After spray rust removal, it can not only expand the physical adsorption effect of the outer surface of the pipe but also enhance the mechanical adhesion effect of the anticorrosive layer and the outer surface of the pipe. Therefore, spray rust removal is an ambitious rust removal method for pipeline corrosion protection. Generally speaking, shot blasting is mainly used for the internal and external treatment of pipes, and shot blasting is mainly used for the external and external treatment of pipes.
Our company also has A312 304L Stainless Steel Pipe on sale, welcome to consult.

As a  Seamless Stainless Steel Tubing Supplier , share with you. Steel resistant to corrosion by weakly corrosive media such as air, steam, and water, and chemically corrosive media such as acid, alkali, and salt is called stainless steel. Stainless steel pipe is a hollow, long, round steel. It is widely used in various industrial transportation pipes and Mechanical structure parts, etc. Here are some of the benefits of using  China Welded Stainless Steel Tubing  for pipeline engineering installation. Duplex Stainless Steel Pipe 1. The stainless steel tube can not only play a good supporting role, but also can transmit liquid materials and gaseous materials over long distances to improve the efficiency of industrial production and make people's lives more convenient and comfortable. High, suitable for the construction of infrastructure in many fields, so it is very common in life. 2. The stainless steel pipe has a hollow section, so it is suitable for liquid, gas and sol

Duplex Stainless Steel Pipe safety restrictions and requirements

图片
Duplex stainless steel pipe safety restrictions and requirements: 1. It is necessary to control the comparative example. The most suitable ratio is that the ferrite phase and the austenite phase are each half, and the number of one phase cannot exceed 65% at most, so as to ensure the best comprehensive performance. If the two ratios are out of tune, such as too many ferrite phases, it is easy to form a single-phase ferrite in the welded HAZ, which is sensitive to stress corrosion cracking in some media. Duplex Stainless Steel Pipe 2. It is necessary to master the organization transformation law of  Duplex Stainless Steel Pipe  and familiarize with the TTT and CCT transition curves of each steel grade. This is the key to correctly guide the process of heat treatment and thermoforming of duplex stainless steel. The precipitation of the brittle phase of duplex stainless steel should be More sensitive than austenitic stainless steel. 3. The continuous use temperature of the dupl
