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:What is stainless steel decorative tube? What uses does it have?
For the steel to withstand the pressure to the hydraulic test to test its ability and quality, leakage, soaked or expansion for qualified does not occur at the prescribed pressure, some steel according to the requirement of standard or edge test, flaring test and flattening test.Seamless stainless steel tube, also called stainless steel seamless pipe, is made of ingot or solid tube blank by piercing, and then made by hot rolling, cold rolling or cold casting. Specifications for seamless steel tubes are expressed in millimeters of outer diameter * wall thickness.
Q:How can the inner walls of stainless steel tubes be polished?
1) (used in polishing the inner surface polishing machine): rod is thrown into the tube to drive the impeller 1000 or homemade abrasive wheel rotating speed, and with the rotation of the polishing pipe itself, while rotating slowly forward throwing rod. Generally speaking, first use the 60#-80# wheel of Chiba or abrasive belt wheel for rough throwing, and then gradually fine throwing with high precision according to the requirement of smoothness. Large size pipe 6, more than the general use of thousands of impeller, small size of the pipe can be made with homemade abrasive belt wheel, you can reduce costs.
Q:The difference between galvanized steel pipe and stainless steel pipe
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 factory uses industrial stainless steel tube to be more?
The automotive industry also has a lot of demand for stainless steel pipes. The main use of stainless steel is the exhaust system, which accounts for more than 1/2 of the total amount of stainless steel in the automobile, and 80% of the ferritic stainless steel. The exhaust gas from the automobile engine flows through the exhaust manifold, front pipe, hose, converter, and central pipe and finally flows out of the muffler. Commonly used in the exhaust system are 409L, 436L and so on. Automobile muffler mainly uses stainless steel pipe. According to estimates, the use of stainless steel pipes in the car accounted for the entire downstream of the stainless steel pipe about 1.5% of the amount, while the use of stainless steel seamless tubes and welded pipe ratio of about 2:1.
Q:Comparison of ring type connection and argon arc welding of stainless steel pipe
Characteristics of argon arc welding of stainless steel pipe:1. Permanent structure, reliable quality;2. Reduce the number of parts used;3. The construction technology is relatively complicated.
Q:Where is the difference between seamless steel pipe or welded pipe?
Seamless steel tube is formed during rolling. Welded steel pipes need to be welded after coiling, and spiral welding and direct welding are generally used. Seamless performance is better, of course, the price is higher.
Q:What is the difference between stainless steel seamless tube and stainless steel welded pipe?
The hot rolling, hot extrusion and cold drawing (rolling) stainless steel pipes are used for rolling.According to the stainless steel metallographic structure, it is divided into half ferrite half martensite system, stainless steel tube, martensitic stainless steel tube, austenitic stainless steel tube, austenitic iron ferritic stainless steel tube, etc..
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 weld sleeves for stainless steel pipes?
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.
