Hot-dip galvanized steel pipe manufacturers popularize the difference between seamless steel pipe and galvanized steel pipe: seamless steel pipe and galvanized steel pipe are different in terms of process, durability, use and prohibition.

Specific differences:

Galvanized steel pipe refers to the steel pipe with hot dip or galvanized coating on the surface. Seamless steel tubes are made of steel ingots or solid tube billets perforated into hand tubes, which are then hot rolled, cold rolled or cold drawn.

Hot-dip galvanizing has the advantages of uniform coating, strong adhesion and long service life. The hot-dip galvanized steel pipe matrix and the molten plating solution composite physical and chemical anti-galvanizing steel pipe should form a corrosion-resistant structure of dense zinc-iron alloy layer. The alloy layer is combined with the pure zinc layer and the steel tube substrate. So it has strong corrosion resistance.

seamless steel pipe

There are many ways to suture. But there is a very common pipeline, that is, the national standard pipeline, also known as the water and gas pipeline, which generally adopts the nominal diameter, which is expressed as the DN nominal diameter.

It is expressed as 3/4 inch and we usually call it a 6 minute long pipe. We usually call it GB pipe, water gas pipe. They are divided into black pipes and hot-dip galvanized pipes.

As we usually say, hot-dip galvanized water gas pipe refers to the national hot-dip galvanized standard pipe, and some people call it hot-dip galvanized steel pipe.

Galvanized steel pipes are usually used as fences, guardrails, guardrails, balcony guardrails, etc. Because it has strong corrosion resistance and wear resistance.

Seamless steel pipes have been widely used in municipal engineering, roads, factories, schools, development zones, gardens, squares, communities and other industries. Due to its large size, seamless steel pipes are standard chemical and mechanical pipes in stone used in petrochemical and machinery manufacturing.

Extended information: Galvanizing can be divided into hot-dip and cold-dip. Galvanized pipes are usually 6 meters long and have blue rings at both ends. No matter how long the weather is, the galvanized pipe will not fall off and the color will not change.

The galvanized layer is thinly plated, the color is light yellow, and it will rust over time. It is often used for electric dark laying lamps in engineering. The wall thickness is also thinner than that of GB pipes. It is used in concrete without rust removal.
