Product Description:

 Non-secondary API Stainless Steel Pipe Made in China

1.Structure of Stainless Steel Pipe

Seamless pipe is formed by drawing a solid billet over a piercing rod to create the hollow shell. As the manufacturing process does not include any welding, seamless pipes are perceived to be stronger and more reliable. Historically seamless pipe was regarded as withstanding pressure better than other types, and was often more easily available than welded pipe.

Q:Ask experts, 304 stainless steel pipe why rust?
Stainless steel corrosion is the dense oxide layer formed on the surface of Cr, to prevent further oxidation of the iron oxide layer, which if destroyed, it is easy to rust, 304 resistance to chlorine ion in chloride solution, low concentration of rust, it will rust quickly in the 304 materials.
Q:Why is stainless steel magnetic?
There are kinds of stainless steel at room temperature, the organizational structure can be divided into several categories: 1. austenitic: such as 304, 321, 316, 310; 2. martensite or ferrite, such as 430, 420, 410; austenitic is non-magnetic or weak magnetic properties, martensite or ferrite is magnetic. Usually used as a decorative stainless steel pipe,Most of the stainless steel plate is Austenitic 304 stainless steel material, is generally non-magnetic or weakly magnetic, but fluctuations in chemical composition caused by smelting or processing of different magnetic properties may also appear, but this can not be considered to be counterfeit or substandard, what is the reason? The above mentioned austenite is non-magnetic or weakly magnetic, and martensite or ferrite is magnetic, due to melting segregation or improper heat treatment, will cause a small amount of martensite Austenitic 304 stainless steel body or ferrite.
Q:Why can stainless steel pipes be welded by argon arc welding?
The arc welding of argon arc welding has the advantages of stable combustion, concentrated heat, high temperature of the arc column, high welding efficiency, narrow heat affected zone, and little stress, deformation and crack tendency of the weldment;
Q:What are the categories of stainless steel pipes with acid and alkali resistance?
Stainless steel is mainly used for acid resistance, alkali resistance is not necessarily very prominent.
Q:Stainless steel pipes can not be less than the amount of chromium
General stainless steel chromium content is generally not less than 12%, high even up to 18%. Steel added elements such as chromium, can change the performance of the steel, such as the molecular structure of steel more uniform on the surface of the steel is more easily to form a layer of dense oxide protective film, thereby greatly improving the ability of corrosion-resistant stainless steel. Therefore, stainless steel can resist fire, water, acid, alkali and various solutions to its corrosion, not rust. The scientists found that the internal structure of the steel is more uniform, various components more closely linked to the corrosion of the more difficult the invasion, also attached to the surface with a layer of oxide film, like iron and steel to wear armor, was not naturally easy to rust. Why is stainless steel rust? When the stainless steel tube surface appear brown rust (point) when people are surprised: stainless steel does not rust, rust is stainless steel, steel may be a problem. In fact, this is a lack of understanding of stainless steel one-sided misconceptions. Stainless steel will rust under certain conditions. 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.
Q:Difference between stainless steel and steel pipe
Stainless steel (Stainless Steel) is referred to as the stainless steel, the resistance of air, steam, water and other weak corrosive medium or with stainless steel known as stainless steel; while the resistance to chemical corrosion (acid, alkali and salt chemical etching) corrosion of steel called acid resistant steel. Because of the difference in the chemical composition of the two, and make their corrosion resistance is different, ordinary stainless steel is generally not resistant to chemical medium corrosion, and acid resistant steel are generally stainless steel.
Q:Why can it stainless steel be put together with carbon steel tube?
An electronic passage formed by wire bonding or direct contact. The carbon in the carbon steel tube loses its electrons to the stainless steel tube and the surface is absorbed by the etchant.
Q:Stainless steel heating oven tube after treatment is heating blue will not be red?
Because sometimes we do tubular heater, in order to better improve its life, will reduce the heating pipe surface power, but it itself heating speed is slow, take more time to reach the temperature you want.
Q:304 stainless steel pipe, 20*2 pressure, how many kilograms?
304 yield strength is 210 R=, thickness D=, outer diameter, P=210/20=10.5, MPa, 1MPa=10, KG, can withstand 105 kg.
Q:Mirror stainless steel tube 60*60 how much is one meter?
Stainless steel tube square weight formula: (pipe circumference / 3.14- actual thickness) * actual thickness *0.02491* length, 0.02491 of which is converted by the stainless steel density of a constant.
