Q:What's the difference between the stainless steel pipe welded pipe and seamless pipe?
Grain size: usually, the grain size of the metal is related to the heat treatment temperature and the time at which the metal is kept at the same temperature. Therefore, the welded pipe and seamless tube annealing of the same grain size. If the minimum tube cold treatment, the grain size of the weld metal is smaller than the grain size, welding or grain size is the same.
Q:Stainless steel pipe drilling?
Stainless steel itself is not high hardness, but it is difficult to processing reasons:Because the stainless steel contains C element is low, hardness is not high, and not easy to deformation, plasticity is poor, this is the iron and steel organization grain concentration caused by. This allows the drill to increase its viscosity when drilling, and it is not easy to chip out. The drill is easy to burn at this time. Through the practice comparison, we know that the opening of 135 degree bit is much easier when the control speed is 300-500 to /min. It is much easier than the drilling of 118 degree hole on the same material.
Q:304 stainless steel will rust it?
Stainless steel is a very thin layer formed on the surface and the stability of the fine solid chromium rich oxide film (protective film), to prevent the infiltration of oxygen atoms, to oxidation, and the ability to obtain anti-corrosion. Once there are some reasons, this film was constantly destroyed, air or liquid oxygen atoms will continue to infiltrate or metal atoms of iron to keep out from the loose formation of iron oxide, the metal surface will be continuously corroded.
Q:Stainless steel and stainless steel pipe inside and outside polishing off, what is the difference?
Deoiling stainless steel tube pipe means no oil after surface cleaning, degreasing bath immersion of the surface to see see oil is not removed, belonging to clean level products, mainly used in pharmaceutical equipment, water equipment, semiconductor and LCD needed for the production of the gas pipeline.
Q:Stainless steel pipes can not be less than the amount of chromium
The chromium content of stainless steel is generally not less than said first why stainless steel tube is not easy to rust 12%-304 stainless steel tube, then why stainless steel will rust stainless steel is not easy to have a great relationship with the composition of stainless steel rust. In addition to iron, stainless steel contains chromium, nickel, aluminum, silicon and so on.
Q:Why pickling before cleaning stainless steel pipe oil?
On the premise of oxide, a good foundation for the formation of passive film is made, which makes the passivation film more compact and improves the passivation effect!
Q:Under what circumstances can the stainless steel pipe be welded by argon arc, and under what conditions can the arc welding be used?
The quality of argon arc welding is high, the efficiency is low, the efficiency of SMAW is relatively high, the quality of secondary pipe welding, general thick such as 10mm are TIG welding, welding rod filler cover, if the pipe is thin directly by argon arc welding
Q:Is food grade stainless steel GB9684 304?
You can't say that.GB9684 is the implementation of standards, 304 is a material of stainless steel, stainless steel material is very much, such as 304321316347310s, 904L and so on, as long as the material of stainless steel in accordance with GB9684 standards of production and processing, can be used as a food grade stainless steel, it should be said that in accordance with the implementation of the standard GB9684 production and processing of food grade stainless steel is 304.
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:Can stainless steel pipes spray black paint
Stainless steel pipes can spray black paint.The surface of stainless steel has a smooth surface
