Q:The difference between stainless steel pipe and stainless steel composite 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 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:What are the weld sleeves for stainless steel pipes?
Quota refers to the quantity standard of manpower, material resources, financial resources and time consumed by qualified units under certain technical and organizational conditions. In the labor organization reasonable and rational use of materials and machinery under the condition of a predetermined number of resources consumed by the completed units qualified product standards, the level of social productive forces, it reflects the level of a certain period of time. For each construction project, the amount of labor is calculated, including basic labor and other labor. Plus the materials for this project, including basic materials and other materials. The unit price is based on the labor value of the different types of work at that time. The value of the material is the budgeted price based on the previous market price.
Q:Stainless steel why are rust?
In polluted air (such as atmosphere containing large amounts of sulfides, oxides of carbon and nitrogen oxides), condensate is formed when sulfuric acid, nitric acid, and acetic acid are subjected to condensation, resulting in chemical corrosion.
Q:Stainless steel pipe 301 material and 304 material what is the difference?
On the surface, hardness is the test, then the material is NI, the difference is so small, the overall price is almost the same. Now, there are a lot of non German, this guy played with 301, when 304 sold.
Q:What color is stainless steel? What color is stainless steel pipe culture?
You want to draw the stainless steel, or to mirror the drawing, usually gray, mirror is generally bright silver, of course, the color is also there, ah, you need it
Q:What wire is used for welding of 316 stainless steel line?
Quality inspection of welding groove preparation, according to requirements of groove size, accuracy and surface quality stipulated in construction instruction and welding process instruction, groove quality including flatness, perpendicularity and cleanness.1, check the groove processing size (height, angle, edge and blunt edge, etc.) and accuracy isDoes it meet the relevant technical standards?.2, check the groove surface roughness and surface defects (cutting gap, crack,Layer and slag) if beyond the scope of the standard should be allowed to defect, repair treatment, such as surface roughness does not reach the standard, can use abrasive grinding.3. Check the surface cleaning quality of the groove. At least 200mm of the groove face and its sidesShould be clean within the scope, without burr, slag, rust, oil, film and paint and other harmful foreign bodies.4 、 nondestructive inspection of groove surface. For welding process documentation, specify the slopeMaterials such as CY-M steel, Fe-CY-N, high temperature steel and alloy steel shall be examined on the surface for nondestructive testing (such as coloring, etc.), and the defects such as cracks shall be removed.
Q:What's lined with stainless steel?
Trenchless stainless steel lining construction method can be widely used in water supply, drainage, gas, heat, telecommunications, electricity, industry and other pipelines. Stainless steel lining pipe, high temperature resistance, can transport hot water, boiling water, steam, and safety and health. The installation of stainless steel tube after the whole bearing pipe resistance, impact resistance, corrosion resistance and other properties to strengthen and enhance the original tube, not only can be used for civilian water and gas, can also be used for fluid transportation industry.
Q:How about stainless steel 2520 and 316?
2520 stainless steel (310S) austenitic chromium nickel stainless steel has good oxidation resistance, corrosion resistance, because of higher content of chromium and nickel content, which has high temperature creep strength, can continuously work under high temperature, good heat resistance. For Ni (Ni), chromium (Cr) content is high, with good oxidation resistance, corrosion resistance, acid and salt, high temperature performance, high temperature resistant steel dedicated to the manufacture of electric furnace tube and so on, increase the amount of carbon austenitic stainless steel, due to the solid solution strengthening effect to the strength improved, chemical composition characteristics of austenitic stainless steel is chrome, nickel based addition of molybdenum and tungsten, niobium and titanium elements, as its face centered cubic structure, and strength and high creep strength at high temperature.
Q:Stainless steel pipe pickling ratio
Usage: apply proper amount of this product onto the surface of stainless steel to be processed, the thickness of 1~2 mm, 5-30 minutes or longer (by dirt, sheet materials and processing requirements), process the best brush a few times, the surface oxide skin, rust completely clean, with water (lime water or salt water better) rinse, avoid rust.
