Service life of stainless steel composite pipe lined with stainless steel
In general, if the stainless steel material and stainless steel composite pipe composite material, if it is the same, it must be pure stainless steel pipe, long service life.
Why use composite pipes, the most important thing is cheaper. However, the composite tube 1. if the diameter is large, the composite pipe made of composite plate has a risk of delamination after crimping. 2. if it is lined with stainless steel pipe, the pressure is less. 3. if the composite pipe joint, welding. The safety factor of compound pipe welding machine is not pure stainless steel.
