As a Seamless Stainless Steel Tubing Supplier, share with you. Welding
connection is a jointless connection, there is no sealing ring inside, it is
welding fixed, and cannot be loosened. Wide range of applications, no problem
with buried walls and exposed surfaces. The tap water pipe can also be used, and
at the same time, it does not need to be maintained and maintained again
Duplex Stainless Steel Pipe
Flange connection means that the two pipelines and pipe fittings are first fixed on one flange piece, the middle of the two flange pieces, and then the flange pad is added, and the bolts are tightened to connect. The benefits are convenient disassembly, high compressive strength, and good sealing characteristics. When installing the flange, it is stipulated that the two flanges should maintain parallel surfaces. The protrusions of the flanges must not be knocked, and they must be cleaned and clean.
Groove connection, also called clamp connection, is a newer type of stainless steel pipe connection. At the same time, it is clearly stated in the design standards of the automatic sprinkler automatic fire extinguishing system that the groove connection should be used for the connection of the system piping. Now it has become a pipeline connection for water, gasoline, gas and natural gas, which is very popular. It not only maintains various valves of the pipeline, but also reduces the damage of parts caused by the pipeline stress.
China Welded Stainless Steel Tubing is a general term for all kinds of stainless steel pipe connection workpieces. It can be divided into different categories according to shape, purpose, and connection method. As a consumer, it is more intuitive to see the surface brightness of the stainless steel tube.
The material of the stainless steel decorative tube is 2B surface stainless steel tape before molding, and the surface of the stainless steel welded tube after molding is smooth. It is also commonly known as rough surface in the industry. This surface is smooth and bright, showing the original color of the metal; After the polishing equipment processing (180 ~ 600 # polishing wheel) polishing grinding treatment can obtain matte surface (round sand / straight wire), also known as matte surface, bright surface and highlight and mirror surface effect.
Several factors that can affect the brightness of stainless steel pipe fittings:
1. Defects on the surface of raw materials. Such as scratches, pitting, scratches, trachoma, over pickling, etc.
2. Products after deep drawing. Small black spots will also appear on the surface of the area with large deformation, which will affect the BQ property.
3. Problems with raw materials. If the hardness is too low, it is not easy to polish during polishing, and the hardness is too low. The surface is prone to orange peel during deep drawing, which affects the BQ property. The BQ with high hardness is relatively good.
4. The oil content of the emulsion is too high. If the oil in the emulsion can not be removed in time after being carbonized at high temperature, it will accumulate on the surface of 304 stainless steel pipe fittings, and indentation will form after rolling.
