Product Description:

1、Structure of Stainless Steel Welded Pipe mechanical Pipe ASTM A554/DIN/EN10296-2/ JIS G3446/GB/T 12770 Description:

Stainless steel welded pipe is actually a cover term, covering a wide range of alloy and making them suitable for different attributes that are used in a very wide and large numbers of different industries. Stainless steel pipe is resistant to erosion, highly flexible, powerful, easy to use, and can be done in distinct approaches, which means that more and more stainless steel was used as a construction material for large-scale, high impact buildings. It can be molded, rolling, and it can create amazing shapes to make it perfect, It is used as experimental buildings. Lightweight traits of hard welded steel pipe makes it perfect for things used in the construction of off shore oil and gas platforms. Crude oil is a corrosive substance and it is positive in the construction of the new drilling platform that uses high alloy, super austenitic welded steel pipe.

Q:What's the easiest way to distinguish between stainless steel 202 and 304?
304# and 202# are American Standard grade 304 is 0Cr18Ni9202shi 1Cr18Nn8Ni5N
Q:Comparison of ring type connection and argon arc welding of stainless steel pipe
Ring type stainless steel pipe connecting end design section of successive and sealing section shape was stepped through the hydraulic tool connection exerts a pressure on the radial deformation of the pipe, stable and sealed sections of Zuohuan extruded and its circumference concave, concave section into which the pipe with forced recess annular snap fastener
Q:What is sanitary stainless steel pipe?
Forbidden oil degree: after the passivation is finished, the cleaning of the forbidden oil is carried out, and the oil pollution on the surface of the steel pipe is removed. After the completion, the grease analyzer is used to check the oil pollution in the pipe wall, and the fluid substance that flows in the pipe is prevented
Q:Stainless steel pipe welding interface leakage, how can we not leak?
Only when the welding quality is improved and the welding defects are reduced can the welding seam position be watertight:Argon arc welding is preferred for stainless steel pipe welding. When the wall thickness is thicker, the backing argon arc welding shall be used preferentially, and the filling and cover surface shall be welded by manual arc welding;The cleaning work before welding should be done well, and all the defects such as burr, oil stain, dust and spot welding should be removed;
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:Is galvanized steel pipe stainless steel pipe?
Galvanized steel pipe is a kind of welded steel pipe, and its essence is hot-dip galvanized coating on the inner and outer surface of welded steel pipe. Hope to be of help to you.
Q:What are the connecting methods of stainless steel pipes for indoor water pipes?
Card convex features: easy installation, the connection is not deformed inside and outside, belong to live connection, easy maintenance. Scope of application: cold water system, pipe direct drinking water system, water treatment equipment system. The installation is more suitable, mainly taking into account the replacement of the sealing ring later, the hot water system should be avoided as far as possible. The advantage of the connection is that the installation is simple, convenient and easy to maintain, and the sealing ring in the pipe needs replacing when aging, and the utility model is relatively simple and convenient, and the nut can be replaced as long as the nut is unscrewed. The disadvantage is that the applicable situation is single, in the hot water system sealing ring aging is more prominent, higher cost. Concealed piping and hot water systems are generally not recommended.
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:Stainless steel seamless steel tube, ordinary seamless steel pipe, which is good?
Stainless steel pipe in the nickel element is relatively high, nickel is pipe rust proof, wear-resistant, mainly corrosion-resistant. The strength of the steel pipe is generally related to the content of carbon in the pipe. The ordinary steel pipe is carbon steel pipe, and the compressive strength is generally better than that of the stainless steel tube.
Q:What are the differences in the properties of hot-rolled and cold-rolled stainless steel tubes?
Stainless steel tube with hot and cold points, hot rolling is made by stainless steel tube billet heated to red state, through processing a mold, which is cold-rolled stainless steel pipe billet collocation through different mould at room temperature, finally by drawing rolling method, stainless steel tube working together the size of the need to.
