1. Indirect fusion methods such as French blue, threaded head, and combination are used
2. The connection is welded. Because galvanized pipe is actually carbon steel pipe, the welding of galvanized pipe and stainless steel pipe is actually the welding of carbon steel and stainless steel, which is the welding of dissimilar materials. Before welding, remove the galvanized layer beside the tank. After soldering, brush with silver powder.
Galvanized steel pipe DN <100 is generally threaded connection, DN> 100 galvanized steel pipe is generally clamp connection. Thread reducer is used to connect DN80 steel pipe and dn70 galvanized steel pipe.
