Production Standard
Different uses of stainless steel welded pipe, the implementation standards are different.
1. Stainless steel welded steel pipe to implement GB/T12771-2008 "stainless steel welded steel pipe for fluid transportation".
Requirements for weld ray flaw detection, hydraulic test or eddy current flaw detection, intergranular corrosion test, flattening test, weld transverse bending test to ensure product quality.
2. Duplex stainless steel welded steel pipe GB/T20832-2008 "austenitic - ferritic duplex stainless steel welded steel pipe".
The main grades are: S22253, S22053, S25073; requirements for weld ray flaws, hydraulic pressure test or eddy current flaw detection, flattening test, weld transverse bending test to ensure product quality; the organization should be austenitic and ferrite, austenitic content should be accounted for 40% -60%.
Advantages
1. Uniform wall thickness - the parent material for the molding of the strip, wall thickness consistency is good, high surface finish, up to industrial grade 2B. 2.
2. low residual stress - after molding the steel pipe using higher than 1040 degrees high temperature on the stainless steel pipe bright annealed to eliminate stress. 3. high strength of the welded seam - high strength of the welded seam.
3. High strength of weld - welding using fusion welding, the material composition remains unchanged, after high temperature heat treatment of the weld and the base material has the same intergranular structure, the weld for flattening, reverse bending, flaring and other destructive experiments, the weld will not be cracked or cracked, burrs and other problems. In addition to this to do eddy current testing and water pressure or gas gas test to ensure the quality of the pipe.
4. Good consistency - the consistency of the outer diameter, wall thickness, length and straightness of the tube is good, and the processing precision is high.
The difference between ss welded pipe and seamless pipe
Stainless steel pipe is mainly divided into two major categories of stainless steel seamless steel pipe and stainless steel welded steel pipe, the most important difference between the two is whether there is a welded seam on the inner wall of the pipe.
First, the difference between the production process:
1. Stainless steel seamless steel pipe is like its name is no welded seam, it is made using round billets as raw materials for piercing, through cold rolling, cold drawing or hot extrusion production process and made, there is no welded joints on the pipe.
2. Stainless steel welded pipe is welded from steel plate or steel strip after being rolled and shaped by unit and mold, and there is generally a weld seam on the inner wall of the pipe.
Second, the difference in thickness
1. The thicker the wall thickness of the seamless stainless steel pipe, the more economical and practical it is, and the thinner the wall thickness, the processing cost of it will rise substantially.
2. Stainless steel welded pipe raw material steel strip are calendered, the thickness is more uniform.
Third, the difference between performance and price
1. Seamless stainless steel pipe is much higher than welded pipe in terms of corrosion resistance and pressure and high temperature resistance; and seamless pipe is more complicated in the production process, and its price is more expensive than welded pipe.
2. With the improvement of the production process of welded pipe, stainless steel welded pipe is slowly approaching the seamless pipe in mechanical properties and mechanical properties.
Fourth, the difference in use
1. Seamless pipe is mainly industrial pipe, especially in high-pressure, high-strength, mechanical structure with superiority.
2. Stainless steel welded pipe is widely used in the field of decorative welding, and also used in the field of medium and low pressure fluid pipe.
Applications
1. Food, medical industry
In the food and medical industries, welded stainless steel pipes are used to manufacture piping systems for the transportation of food or pharmaceuticals. Such piping systems need to have a high standard of hygiene and easy to clean, so stainless steel welded pipe has become the first choice.
2. Petroleum, chemical industry
In the petroleum and chemical industries, stainless steel welded pipes are widely used in piping, equipment, tanks and other areas. As these equipments often need to be exposed to acidic, alkaline and other corrosive environments for a long time, they need to have high corrosion resistance, and welded stainless steel pipes are widely used because of their excellent corrosion resistance.
3. Construction field
Construction of common equipment such as steel structures, ventilation pipes, stair railings, etc., all need to use stainless steel welded pipe. Stainless steel welded pipe is characterized by high strength, beautiful appearance, and not easy to rust, and is widely used in the construction field for decoration and manufacturing of structural components.
4. Other industries
Stainless steel welded pipes are also used in the manufacture of parts and piping systems in the industries of ships, automobiles, trains, machinery and equipment. Stainless steel welded pipe is widely used in the field of industrial production due to its high strength, wear resistance, corrosion resistance, easy processing and other characteristics.
