How to bend Stainless Steel Seamless Pipe?

There are many ways to make Stainless Steel Seamless Pipe. Some customers require stainless steel seamless pipes to be rounded. So how should this be done? Let ' s take a look at the manufacturing method of stainless steel seamless tube with Seamless Stainless Steel Tubing Supplier.

Stainless steel seamless pipe is long steel with a hollow cross-section and no seams on the periphery. The thicker the wall thickness of the product, the more economical and practical it is. The thinner the wall thickness, the higher the processing cost. Therefore, it shows its superiority in terms of high pressure, high strength, and mechanical structural materials.

1. If not required, both sides are recessed inward to avoid cracking of stainless steel seamless pipes;

2. If there is a requirement that the surface of the stainless steel seamless tube cannot be concave, the use of a plug method can be guaranteed;

3. The raw materials of stainless steel seamless pipes must be qualified;

4. The inner side of the stainless steel seamless tube is recessed, that is, there is a protrusion in the middle of the inner mold of the bending machine, and the inner side of the stainless steel seamless tube can be pressed out of a groove during bending. 

The outer galvanized and plastic coated steel pipe of seamless pipe is the same as the plastic coated steel pipe. It is based on a steel pipe. The pipe is a steel pipe with a coating inside and outside. Generally, the internal coating is plastic for corrosion protection. According to the needs of users, plastic or galvanized layer can be selected, and other coating materials can also be used.

In addition, the methods of galvanizing the surface of seamless pipes mainly include hot-dip galvanizing and electro-galvanizing. There are wet, dry, lead-zinc, and redox methods.

The main difference between different methods of galvanizing hot-dip galvanizing is the method of activating the surface of the pipe body to improve the quality of galvanizing after the acid leaching and cleaning of Wuxi Shengtianxiang seamless pipe. Dry production and redox methods are mainly used in production.

The surface of the zinc layer of the electrogalvanized ground is very smooth and dense, and the structure is uniform; it has good mechanical properties and corrosion resistance; the zinc consumption is 60% to 75% lower than that of hot galvanized. Electrogalvanization is technically complicated, but this method must be used for single-sided coating, double-sided coating with different thicknesses on the inner and outer surface and seamless tube galvanizing.

What are the methods to remove the oxide scale of stainless steel pipes? There are mechanical, chemical and electrochemical methods to remove the oxide scale of stainless steel pipes. Due to the complexity of the composition of the oxide scale of the stainless steel tube, it is not easy to remove the surface oxide scale and achieve a high degree of cleanliness and smoothness on the surface. The removal of oxide scale on stainless steel pipes is generally carried out in two steps. The first step is pretreatment and the second step is ash removal.
