Different from the black steel pipe, the stainless steel pipe is made with special craft. So during the usage of stainless steel pipe, we need to pay special attention. The stainless steel pipe tips can be described in nine points. In the rest of this passage, we will explain them in detail, respectively. The first point we will mention among the nine stainless steel pipe tips is transportation. When transporting the stainless steel pipe, it should be separated from other metal materials. We should use plank or rubber sheet to wrap the stainless steel pipe up. Because stainless steel pipes are smooth on the surface, we need to pay special attention to avoid the pipes being hurt. The second point we will mention among the nine stainless steel pipe tips is incision.

When incising the stainless steel pipes, we should use the particular grinding wheel which is specially designed for cutting stainless steel pipes. The common grinding wheel is not suitable. The third point we will mention among the nine stainless steel pipe tips is positioned welding. When we deal with positioned welding of the stainless steel pipes, we should fill argon in the inside of welding line to protect the pipes. The fourth point we will mention among the nine stainless steel pipe tips is the welding method of arcing. The starting arc should use reflowing welding while the closing arc should fill arc crater. The fifth point we will mention among the nine stainless steel pipe tips is connection.

Before connecting the stainless steel pipelines or stainless steel fittings, or connecting the stainless steel pipelines or stainless steel fittings with non- stainless steel pipelines or fittings, we should fill argon into the pipe to protect the stainless pipes. The sixth point we will mention among the nine stainless steel pipe tips is that when we deal with the welding of several stainless steel pipes, we should use multi-layer welding and the closing arcs should be staggered. The seventh point we will mention among the nine stainless steel pipe tips is dealing with welding line. When finishing the welding of stainless steel, we should let the welding line undergo acid pickling and passivation treatment.

The eighth point we will mention among the nine stainless steel pipe tips is the welding temperature. When dealing with the continuous welding of stainless steel pipe, the welding temperature should be less than 60 ℃. The ninth point we will mention among the nine stainless steel pipe tips is also the last point. The hydrostatic test of stainless steel pipe fittings has certain requirements of the water temperature and the water quality. The water temperature should be more than 5℃ and the chlorine ion content in the water should be less than 25ppm.
