How to weld galvanized pipes? What precautions should be taken?
Measures to ensure welding quality include: 1. Human factors are the key focus of galvanized pipe welding control. Due to the lack of necessary post-welding control methods, it is easy to cut corners, which affects quality; at the same time, the special nature of galva...Read more -
What is galvanized steel ? How long does the zinc coating last ?
Galvanizing is a process where a thin layer of a second metal is applied to the surface of an existing metal. For most metal structures, zinc is the go-to material for this coating. This zinc layer acts as a barrier, protecting the underlying metal from the elements. T...Read more -
What is the difference between galvanized steel pipes and stainless steel pipes?
Essential differences: Galvanized steel pipes are made of carbon steel with a zinc coating on the surface to meet daily usage requirements. Stainless steel pipes, on the other hand, are made of alloy steel and inherently possess corrosion resistance, eliminating the ne...Read more -
Does galvanized steel rust? How can it be prevented?
When galvanized steel materials need to be stored and transported in close proximity, sufficient preventive measures should be taken to prevent rusting. The specific preventive measures are as follows: 1. Surface treatment methods can be used to reduce the forma...Read more -
How to cut metal?
The first step in metal processing is cutting, which involves simply severing raw materials or separating them into shapes to obtain rough blanks. Common metal cutting methods include: grinding wheel cutting, saw cutting, flame cutting, plasma cutting, laser cutting, a...Read more -
