How to identify types and application of welded steel pipes

Steel tube is often used as a kind of construction material. Due to different steel pipe production, there are several types of production of steel tube and wider application field is welded steel pipe. What is welded steel pipe? In fact, it is a kind of steel tube made of welding, which is made into a steel sheet. The raw material of welded steel pipe is a steel plate injected into a certain mold, then it will be welded into a fixed shape. This type of steel pipe is made of welding, which will not be crevice and is more stable. Therefore, it will be used frequently during construction. According to the field of application, welding steel tube specifications are different.

The welding steel tube specifications have the different sizes such as different diameter as well as the pipe thickness. In terms of steel pipe shape, the two common shapes in the steel pipe market are round steel pipe and square steel pipe. In these two different shapes, there are different specifications. Taking the specification of the round steel pipe as an example, we can find that there will be a specification chart including the content of pipe thickness, internal diameter, external caliber and so on. This is to adapt to the different strengths and pressures that are needed in the production life. In general, the welding steel pipe specifications are still very much and complex and all kinds of specifications can meet the requirements of any production operation at present.

The types and applications of welded steel pipes are closely related. According to the material, the more common one is hot dipped galvanized steel pipe. In fact, ordinary steel tubes are coated with zinc to apply to specific areas. This kind of steel tube is different according to the zinc plating. In welding steel tube, how to distinguish hot-galvanizing steel pipe is always a more important point for buyers and users.

In fact, it is very simple to distinguish the steel pipe. The first thing to know is that hot galvanizing is actually done after the completion of the steel pipe. Steel pipe manufacturers need to protect pipes by galvanizing. So galvanizing effect is very important for pipe quality. If you want to buy this kind of hot galvanizing steel tube, you can judge it from zinc surface and zinc layer thickness is obvious. If you have any doubts, please contact us freely.
