Product Description:

1、Structure of Stainless Steel Welded Pipe ASTM A249/A269; GB/T24593:

    Stainless steel Welded pipe is used in applications that require the pipe to have high anti-corrosive properties. Compared to steel and cast iron pipes, stainless steels are more flexible, durable and have a higher strength. They are very resistant to erosion-corrosion and can be formed and welded into various shapes and sizes. It is easily connected with various other piping systems and materials and is designed to withstand long life cycles.



2、Main Features of Stainless Steel Welded Pipe ASTM A249/A269; GB/T24593:

• High manufacturing accuracy

• High strength

Q:What is stainless steel decorative tube? What uses does it have?
Stainless steel decorative tubes, decorative stainless steel tubes, made of stainless steel anti-theft windows, stainless steel railings, stainless steel staircase handrails, interior modeling, etc.
Q:Under what circumstances can the stainless steel pipe be welded by argon arc, and under what conditions can the arc welding be used?
From the economic point of view and flexibility, arc welding is good, from the efficiency aspect, of course, argon arc welding is higher, the effect is better, and also more mechanized. If it is small batch, it will choose arc welding.
Q:How much more expensive is 304 stainless steel than 201?
304 stainless steel is a common stainless steel material, the density of 7.93 g/cm3, the industry is also called 18/8 stainless steel. High temperature resistance of 800 degrees, with good processability, high toughness characteristics, widely used in industry and furniture decoration industry and food and medical industry. The common marking methods in the market are 06Cr19Ni10, SUS304, in which 06Cr19Ni10 is generally used to indicate standard production of the national standard. Generally speaking, ASTM standard production is indicated, and SUS 304 represents standard production.
Q:What is the difference between stainless steel tube 304L and 304N?
The lower carbon content minimizes the precipitation of carbides in the heat affected zone near the weld, while the precipitation of the carbides may lead to intergranular corrosion in stainless steels in certain environments.
Q:Mirror stainless steel tube 60*60 how much is one meter?
Examples are stainless steel 63 round tubes, solid thickness 0.82 stainless steel tubes, single support 6 meters long, weight (63-0.82) *0.82*0.02491*6=7.62kg, a six meter long 63 round tube, thickness 0.82, theoretical weight is 7.62kg;
Q:310 stainless steel resistance to high temperature?
Features: suitable for making all kinds of furnace components, with a maximum temperature of 1200 degrees, continuous use temperature of 1150 degrees CelsiusUses: furnace materials, materials for automotive cleaning equipment
Q:304L stainless steel pipe can withstand 0.1MPA?
Stainless steel pipe is a kind of hollow long strip round steel, mainly used in petroleum, chemical, medical, food, light industry, machinery, instrument and other industrial pipeline and mechanical structure parts. In addition, the bending and torsional strength of the same weight is lighter, so it is also widely used in the manufacture of mechanical parts and engineering structures. It is also used to produce all kinds of conventional weapons, guns, shells and so on.
Q:What are the weld sleeves for stainless steel pipes?
Set of galvanized steel pipe stainless steel pipe according to the material quota.
Q:304 stainless steel will rust it?
Stainless steel has the ability to resist atmospheric oxidation - that is, stainless steel, and also has the ability to corrode in medium containing acids, alkalis, and salts - that is, corrosion resistance. But its corrosion resistance is changed with the chemical composition, the mutual state, the condition of use and the type of environmental medium. Such as the 304 steel pipe, in the dry clean atmosphere, have absolutely excellent anti-corrosion ability, but it will be moved to the beach area, with large amounts of sea salt fog, will rust quickly; and the good performance of 316 steel pipe. Therefore, it is not any kind of stainless steel, capable of corrosion and rust in any environment.
Q:Water and electricity thin wall stainless steel tube 304 material delta 2 what does that mean?
304 stainless steel is a universal stainless steel material, antirust performance than the 200 series of stainless steel material stronger.
