Penetration depth of molten stainless steel welded pipe requirements, do not contain oxide inclusions, heat affected zone as small as possible, argon arc welding of tungsten inert gas protection has good adaptability, high welding quality and good penetration performance, its products in the chemical industry, nuclear industry and food industries widely used.
Original drive run-up, strength test on line or leak test, a333 grade 6 pipe can't and the connected equipment (such as turbine, compressor, gasifier, reactor, etc.) together with the case, to be in a setting of equipment and pipeline connecting the blind flange.
304 is a kind of common stainless steel, it is widely used in rough performance, corrosion resistance and formability) equipment and parts. In order to adhere to the inherent corrosion resistance of stainless steel, chromium steel contains more than 18, eight more than the nickel content. 304 stainless steel is in accordance with the United States ASTM standard produces a brand of stainless steel.
Stainless steel plate is brown rust colors how to deal with, when the x60 line pipe stainless steel plate is brown rusty spot (point), the big surprised: people think that "stainless steel is not rusty, rust is not stainless steel plate, steel presents a might be the problem". In fact, it is short of stainless steel plate a one-sided understanding of the fault point. Physical features: heat resistant, high temperature resistant, also resistance to low temperature even ultra-low temperature;
Speaking of stainless steel plate everyone will not feel strange, 316l stainless steel pipe this plate appearance is very light, during the period of use can also be combined with the specific requirements for manufacturing, is a kind of very high plasticity. During the use of stainless steel, come into contact with acid or alkaline substances is after reducing chemical information won't be any change, you can stick to basic stability. A lot of people think that the first combination required specification of stainless steel for planning manufacturing can, of course this is one of the processing of stainless steel materials, actually in manufacturing this kind of data but also follow certain hard Numbers.
Mechanics function: according to the different varieties of stainless x70 line pipe steel, mechanical function is different. Martensite stainless steel with high strength, hardness, suitable for corrosion resistance and high strength, high abrasion resistance parts, such as turbine shaft, stainless steel cutlery, stainless steel bearings, etc. Strength of austenitic stainless steel and plastic is very good, not too high, but is stainless steel Chinese super good corrosion resistance, suitable for very corrosion resistant and mechanics function requirement is not high, such as chemical factory, chemical fertilizer plants, sulfuric acid, hydrochloric acid manufacturers of printing equipment, etc.
