[Specifications] -An stainless steel pipe accessories OD: 38mm / 1-1 / 2 inches, wall thick
[Advantage] -90 degrees of weld short elbow, connect two pipes or pipes from a certain angle, welding connection to ensure closely sealing and reduce the possibility of leakage
[Features] -The long radius 90 degrees elbow, which is used to change the direction of flow. Suitable for using water, oil and gas and gas and other liquid
The 304 groove stainless steel pipe parts only need to be equipped with standard parts stainless steel stuck, bolts, and sealing rings to install the pipeline. The construction efficiency is high, which can effectively shorten the pipeline installation cycle and do not need to be welded. Therefore Use more users to accept
[Material] -Welding short elbow tube accessories are made of 304 steel, which has good seismic performance, good corrosion resistance and acid resistance
[Application] -304 application in the field of decoration. Because the SS 304 Welded Elbows pipe has a high tensile strength and good internal cavity smoothness and wear resistance, it has been widely used in the field of decoration. Like the common stainless steel stairway fences, stainless steel protective windows, stainless steel courtyard doors, stainless steel tables and chairs, etc., all are controlled by 304 stainless steel decoration. Many 304 stainless steel pipe manufacturers have also developed the design and model specifications of many 304 stainless steel decorative tubes for many customers to choose from. This 304 stainless steel pipe is a favorite decorative material for everyone
SS 304 WELDED ELBOWS production process:
First of all, the first step is to cut the raw material tube and cut the feeding, calculate according to the distance from the product center to the end surface, and then put it in an orderly cut in the lathe.
Secondly, we are ashes the cut tube. The role of the ash process is lubricating to ensure the beauty of the outside surface of the pipe. If there is no ash, there will be obvious strip marks on the surface of the pipe.
After the tube is ash, the suppression link is reached, and the suppression is divided into the core stick push and the ball pushing.
Then the annealing treatment is performed to heat the elbow to a certain temperature and heat it for a period of time, so that it will cool down slowly. The annealing is one of the quality factors that determine the elbow molding, which improves the mechanical properties of the thermal pressure elbow and reduce the residual stress; at the same time, reduce the hardness, improve the plasticity and toughness, and improve the processing of processing.
Next is to pick up. The corrosion resistance of stainless steel pipe parts mainly comes from the reaction of the chromium in it contained in it, and a dense anti -defense layer is formed on its surface. The role of pickling is to allow it to react in advance to improve the corrosion resistance of stainless steel pipe parts. During the picking process, the oil pollution attached to the surface of the tube and other substances contained in production in production will be removed.
Then the product is fully polished, and the function of mechanical, chemistry or electrochemistry is used to reduce the roughness of the workpiece surface to obtain the light and flat surface processing method.
Finally, the backward angle is carried out. In order to remove the burrs generated by the machine processing and facilitate the assembly of the parts on the parts, make a chamfer on the part of the part
