Hot galvanised pipe is an anti-corrosion steel pipe with a zinc layer coated on the surface of the steel pipe, which is commonly used in construction, bridges, barricades and other fields. Seamless steel pipe, on the other hand, refers to the steel pipe without welding in the production process, which has good sealing and strength and is suitable for petrochemical, automobile, ship and other fields.

1. Different production processes

The production process of hot galvanised pipe is to clean the surface of the steel pipe first, and then spray a layer of zinc liquid, so that it reacts with the surface of the steel pipe at high temperature to produce a layer of zinc. The production process of seamless steel pipe is to heat the steel ingot to a certain temperature, and then use the steel pipe apparatus that penetrates the steel ingot to penetrate the steel ingot into a tube, and then through the bending, processing and other steps to shape it.

2. Different areas of use

The anti-corrosion effect of hot galvanised pipe makes it widely used in construction, bridges, barricades and other fields. And the good sealing and strength of seamless steel pipe make it suitable for petrochemical, automobile, ship and other fields.

3. Different prices

Due to the different production processes and areas of use, the price of hot galvanised pipe and seamless steel pipe is also different. Generally speaking, the price of seamless steel pipe is slightly higher than hot galvanised pipe.

Hot galvanised pipe and seamless steel pipe have their own unique advantages and areas of application, the choice of which steel pipe to use according to the specific needs and industries to determine. In the development of construction, petrochemical, automotive and other industries, both have a wide range of applications
