Closed Cooling Tower Stainless Steel Coil

Forming Method of Stainless Steel Coil for Closed Cooling Tower

The coil is one of the indispensable parts in the closed cooling tower. It can be made of many materials, among which copper pipe, carbon steel pipe and stainless steel pipe are more common. But no matter what kind of production technology, I wonder if it is also so diverse in terms of processing technology?

For closed cooling tower coils made of stainless steel, there are three manufacturing processes, one is the direct welding method. It only needs to process the flaring on the semicircular elbow, then insert the straight pipe into the flaring of the elbow, and use argon arc welding to weld it to form it. However, direct welding has relatively high requirements for welding. Once leakage occurs, it will be very difficult to repair. But it also has advantages, that is, it can greatly reduce the cost of stainless steel coils in closed cooling towers.
The other is sealing and clamping through rubber rings. This molding process is rarely used, mainly because the technology is not mature and there are many problems. So let’s talk about another method of directly bending straight pipes into S-shaped coils. Most of the coils of closed cooling towers use this technology. The coil pipe formed by direct bending has higher reliability and reduces the possibility of leakage, but it needs to be improved due to high cost and troublesome manufacture.www.gwbrefrigeration.com
