Common problems and solutions during the cold working and forming process of stainless steel
(1) Because there are defects such as dirt, scratches, pits, pits or heavy skin on the surface of the blank to be processed, these defects are amplified along with the processing deformation of the blank during the cold forming process, which directly leads to dirt and corrosi...Read more -
Why are 304 and 316 stainless steel pipe fittings magnetic
In real life, most people think that stainless steel pipe is non-magnetic and use magnets to identify stainless steel. This method is very unscientific. People often think that magnets absorb stainless steel to verify its quality and authenticity. If it does not attract non-ma...Read more -
Steel elbow process flow
Seamless steel elbow: Steel elbow is a kind of pipe fitting used at the end of a pipeline. Among all the pipe fittings used in the pipeline system, the proportion is about 80%. Usually, different forming processes are selected for steel elbows of different materials or wall th...Read more -
Some installation points about stainless steel pipe fittings
The installation method of stainless steel pipe fittings is the same as that of ordinary carbon steel pipe fittings, but there are some special requirements in certain processes. as follows: 1. When lifting stainless steel pipe fittings, they should not be in direct contact wi...Read more -
Characteristics and scope of application of thin-walled stainless steel pipe socket argon arc welding construction method
The socket argon arc welding construction method has the following characteristics: 1. The welding process does not require welding materials (replaced by expanded pipe edges). The stainless steel pipe is inserted into the pipe fitting socket, and the end of the socket is weld...Read more -
Advantages of straight seam steel pipes and steel structure applications
Straight seam steel pipe is a steel pipe welding process that is opposite to spiral steel pipe. The welding process of this kind of steel pipe is relatively simple, the cost of welding is relatively low, and it can achieve high efficiency during production, so it is relatively...Read more -
Comparison of advantages and disadvantages of thin-walled stainless steel pipe connection methods
1. Mutual learning of domestic and foreign stainless steel pipe standards. The internationally common stainless steel pipe connection methods mainly include compression type (convex type), pressing type, push type, welding type (socket argon arc welding type and butt welding t...Read more -
Spiral steel pipe connection methods
Generally speaking, the connection method of spiral steel pipes is welding, because welded pipes are relatively low-cost. Some projects will also use other connection methods such as threads due to construction period, construction conditions, geographical environment, and oth...Read more -
How to solve the deformation problem of spiral submerged arc welded steel pipes
The spiral seam submerged arc welded steel pipe is rotated and drilled and begins to enter the soft formation. Under the action of the three-cone wheel, the drill bit first produces elastic shear deformation of the formation and then is removed under the pressure of the three-...Read more
