How to distinguish galvanized steel pipe

Galvanized steel pipe is a kind of pipe which is very popular in the market and it is also different compared with ordinary pipe. The difference is that galvanized steel pipe is formed by further processing on the basis of ordinary steel pipe. The further processing is that ordinary steel pipe is coated with a layer of zinc then galvanized steel pipe is manufactured, a pipe which possesses good insulation performance.

Galvanized steel pipe can be divided into two types that is cold galvanized steel pipe and hot dipped galvanized steel pipe. If the steel pipe is immersed into the zinc solution directly, the processing is called hot dip galvanizing. After cooling, the steel pipe will be coated with a layer of zinc which can prevent rusting. The zinc surface can protect the steel pipe so that it can have a long service time. Generally speaking, the performance of hot dip galvanized steel pipe is better than that of cold galvanized steel pipe so the price is also higher than that of cold galvanizing.

Another galvanized steel pipe is pre galvanized steel pipe which is more widely used in construction because of its high durability, weld consistency, reliability. The product can be manufactured with different specifications and the shape can be round or square. The difference between round tube and square tube is their cross section. In the same case, the insulation property will be the same but different shapes cater to different applications.

When purchasing galvanized steel pipe, distinguishing steel pipe according to the purposes is a very important issue. The distinction between hot dip galvanizing and cold galvanizing is quite obvious. The zinc thickness of the two products exists a big difference because of the different galvanizing method. The zinc layer of hot dip galvanized steel pipe is thicker than that of cold galvanized steel pipe and you can see the zinc layer very clearly. In today’s market, there are lots of downstream industries of this type of steel pipe. For example, galvanized steel pipe can be used in the electrical industry because its insulation performance is very competitive. Besides line installation and other industries also need this kind of steel pipe so the market is prosperous. Steel pipe manufacturers in China should seize the opportunity to improve overall promotion. They can expand their product scope and collect more information so that they can understand the demands of different customers. As a purchaser, you should also learn some professional knowledge to identify the differences between different products.
