As a  Welded Pipe Stainless Steel Supplier , share with you. Stainless Steel Pipe Ferritic  generally has a pure ferrite structure at room temperature, which is not very high in strength, ductility and good toughness; if it is heated to high temperature, a small amount of austenite structure may also appear (lower for chromium Steel) or no austenite structure appears at all. Therefore, under the effect of thermal cycling during welding, there may be a small or no martensitic structure. Therefore, this type of steel does not have the problem of significantly reduced strength or quench hardening after welding, and even a small amount of martensitic structure can be solved by post-weld heat treatment. It can be said that the room temperature strength of this type of steel welded joints is not the main contradiction of welding; moreover, because its welding thermal expansion problem is far less than that of austenitic stainless steel, its hot and cold cracking problems are also not very

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

Industrial development is changing rapidly.  China Welded Stainless Steel Tubing  also follows the development of the industry to meet the development needs of various industries. The following  Welded Pipe Stainless Steel Supplier  takes everyone to understand the wide application of stainless steel pipes in various industries. Stainless Steel Pipe Ferritic 1. Water supply and drainage pipelines and irrigation systems The water supply and drainage pipeline project is a pipeline (drain) system project that transports and distributes industrial water supply, domestic drinking water, and collects, transports, and discharges industrial wastewater, domestic sewage, and rainwater. Its engineering investment accounts for most of the total engineering investment. The sprinkler irrigation system is an important part of agricultural water use. The physical and chemical characteristics of stainless steel water pipes meet the requirements of modern agricultural water treatment. 2. Dire

Seamless Stainless Steel Tubing Supplier  tells everyone about seamless tube surface pretreatment! The outer galvanized and coated steel pipe of seamless pipe is the same as the plastic coated steel pipe. It is based on steel pipe. The pipe is a steel pipe with a coating inside and outside. According to the needs of users, plastic or galvanized layer can be selected, and other coating materials can also be used. Stainless Steel Seamless Pipe Therefore,  Stainless Steel Seamless Pipe  with galvanized and plastic coated surface should be surface pretreated first. The specific processing steps are as follows: 1. Before shot blasting and rust removal, preheat the seamless pipe to dispel moisture, and the preheat temperature is 40 ℃ ～ 60 ℃; 2. The rust removal shall reach the Sa2.5 level in GB / T8923, and the depth of the anchor marks on the seamless pipe surface is 40μm ～ 100μm; 3.Residual rust and dust on the surface of the seamless pipe should be removed; 4.
