The seamless steel pipe is formed in one piece and is directly perforated with round steel. There is no weld on the surface, and it is widely used. What are the uses of the seamless steel pipe? Let’s take a look.

What are the uses of seamless steel pipes?

Seamless steel pipes are used in a wide range of applications, including structures, fluid transportation, low and medium pressure boilers, high pressure boilers, fertilizer equipment, oil cracking, geological drilling, diamond core drilling, oil drilling, ships, automotive half shaft casings, diesel engines, etc. , seamless steel pipes will be used, and the use of seamless steel pipes can avoid problems such as leakage, which not only ensures the use effect, but also improves the material utilization rate.

It can be seen that the application of seamless steel pipes mainly reflects three major areas:

One is the construction field, which can be used for underground pipeline transportation, including groundwater extraction when building buildings;

The second is the processing field, which can be used in machining, bearing sleeves, etc.;

The third is the electrical field, including pipelines for gas transmission and fluid pipelines for hydropower generation.

What are the characteristics of seamless steel pipes?

The biggest feature of seamless steel pipe can be seen from the name, that is, there is no gap, because the steel pipe is a metal component. If it is to be connected, it must be welded. At this time, there will be welds. If the welding is not good , it is easy to bring inconvenience to use. The seamless steel pipe has no welded seams and can withstand the pressure from the inside very well.

Because of its own structure, seamless steel pipes are widely used in applications. Basically, seamless steel pipes are used for important transportation. It can be used to input oil, natural gas, gas, water and other fluids, and can also be used to transport some solid material.

The seamless steel pipe is made of round steel perforation. Corresponding to the steel pipe formed by hot bending of the steel plate, it has better bending and torsional strength, and the pressure bearing effect is better.

How is seamless steel pipe made?

The production process of seamless steel pipe: round pipe blank → heating → perforation → three-roll skew rolling, continuous rolling or extrusion → pipe removal → sizing (or diameter reduction) → cooling → straightening → hydraulic test (or flaw detection) →marking→warehousing

The production process of seamless steel pipe can be divided into two types: cold-drawn and hot-rolled. The production process of cold-rolled steel pipe is generally more complicated than that of hot-rolled steel pipe, but the dimensional accuracy of cold-rolled steel pipe is higher than that of hot-rolled steel pipe, and the surface  looks brighter than the thick-walled seamless steel pipe, the surface is not too rough, and the caliber does not have too many burrs.
