Cold Drawn ASTM A312 AISI 201 304 304L Seamless/Welded Stainless Steel Round Tube/Pipe

In general, professional authoritative testing institutions are divided into the following parts to determine whether 304 stainless steel pipe is qualified:
1. Surface quality
It is generally required that the outer surface of the pipe should be clean, without cracks, folding, stratification, pickling traces and oxide iron sheet. The surface roughness of the circular tube shall not be lower than Ra0.8.
2. Size deviation
Detection unit has standard requirement to the outside diameter and wall thickness of pipe material, but different application scope can have different requirement, specific should be asked when purchasing.
3. Appearance quality
The two ends of the pipe should be perpendicular to the axis of the pipe and should be smooth. Minor deformations and minor defects due to the cutting method are allowed.
4. Mechanical properties and process properties
Tensile strength, yield strength and elongation after fracture are the main factors to determine the mechanical properties of a pipe, which are related to whether it can be processed or applied in some fields. The flattening test is to test the process performance, to see if there are cracks and cracks when the steel pipe diameter is flattened to 2/3.
Chemical composition
Detection of chemical composition is the most direct determination of a pipe is authentic 304 stainless steel pipe.
6. Corrosion resistance
This is a performance point that consumers are very concerned about, and it is also one of the natural characteristics of stainless steel. So corrosion resistance is also a key detection unit of data.

Advantage one: health and environmental protection

The inner wall of stainless steel conduit is smooth, although use for a long time also do not knot scale, do not suffer bacterial pollution, need not worry about water quality is affected, can avoid water effectively the secondary pollution. After the immersion test, all the indicators are in line with the national drinking water standards. Accordingly, choose conduit of 304 stainless steel to be helpful for health more.

Advantage two: corrosion resistance

304 stainless steel pipe is one of the most widely used chrome-nickel alloy, all because of its chemical performance is more stable, so 304 stainless steel pipe is in the performance of anti-corrosion respect more outstanding.

Advantage three: high toughness

304 stainless steel has the characteristics of good processing performance and high toughness, so 304 stainless steel pipeline in the production process is higher than the quality of ordinary stainless steel.

Advantage four: high temperature resistance

304 stainless steel tube is more resistant to high temperature than ordinary stainless steel tube. For example, the high temperature of 800℃ is within the tolerance range of 304 stainless steel water pipes, but ordinary stainless steel water pipes may be damaged by this temperature.

Jiangsu Irunt Steel Group Co., Ltd. is located in Wuxi City , Jiangsu Province, China, which is the largest steel production base. After 30 years of efforts, it has grown from a family factory to a group company.

The group company mainly produces and sells a series of steel products such as steel pipe, steel coil, steel plate, copper pipe, copper plate, copper strip, aluminum pipe, aluminum plate, galvanized steel pipe, galvanized coil, galvanized plate and so on.The group company has established five platforms, including three production plants and two processing plants. At present, it is still expanding its production line, basically forming a development model of integration of production, processing and sales.

Our annual production capacity of various specifications is about 1 million metric tons. In addition to being a supplier of our series of products, the group company is also committed to expanding its commitment to customers by strengthening services and adding new facilities. A dedicated team is responsible for providing technical support, recommending the correct use of steel, and assisting customers to give full play to their products.

Over the years, we have opened up new markets in Africa, Southeast Asia, the Middle East and America. Our best service and excellent quality have led long-term partners in many countries and established continuous business relations with all customers. Our principle is "service first, sales second". Most of the time, we have comprehensive inspection and procurement to control the quality of finished products. We will have a professional inspection team to test each delivery of products.

Since its establishment, in line with the mission of "contributing high-quality products and services to the world" and the core values of "customer first, excellence, coexistence and win-win", we ensure that we can deeply cooperate with all our friends in the field of iron and steel, and win more affirmation and praise from the market and customers with its high-quality products, perfect product team and thoughtful service, I believe tomorrow will be better!
