What are the process flows of hot rolled steel pipes
Hot rolled steel pipe, as the name suggests, is a steel pipe rolled at high temperature. Its production process can be said to be an epic of metal deformation, full of heat and deformation. The following is a simple description of the hot-rolled steel pipe production process: Everything starts wi...Read more -
5 commonly used heat treatment processes for seamless steel pipes
What are the five commonly used heat treatment processes for seamless steel pipes? There are many varieties of seamless steel pipes, and the steel grades (species) used are also different. The chemical composition of steel pipes of the same type may also have certain differences, but after heat t...Read more -
Detail of industrial precision bright steel pipe
Precision bright steel pipe is a high-precision steel pipe material that is processed by precision drawing or cold rolling of ordinary seamless steel pipe (or diameter-reduced welded steel pipe). Because there is no oxide layer on the inner and outer walls of precision bright steel pipes, they ca...Read more -
How to join seamless square steel pipes
There are three butt methods for seamless square steel pipes, namely electric welding butt, pipe hoop and trench butt, and flange butt: 1. Welding and docking method Welding and butting two seamless square steel pipes is a common butt method. This method is more time-consuming, but it improves ov...Read more -
Welding method of galvanized steel pipe
Galvanized steel pipe has the dual advantages of corrosion resistance and long service life, and the price is relatively low, so its usage rate is getting higher and higher now. However, some users do not pay attention when welding galvanized pipes. It has caused some unnecessary trouble. So what...Read more -
The uses, characteristics, and selection methods of welded steel pipes and seamless steel pipes
In the steel industry, welded steel pipes and seamless steel pipes are two common and important pipe types. Each of them has unique characteristics and applicable scenarios. The correct selection and application of these two steel pipes are of great significance for ensuring project quality and i...Read more -
Common storage methods for steel pipe
First, choose a suitable site and warehouse 1. Do not store them together with acid, alkali, salt, cement, and other materials that are corrosive to steel pipes in the warehouse. Different types of steel pipe should be stacked separately to avoid confusion and contact corrosion. 2. Large steel se...Read more -
Material characteristics and pressure-bearing capacity of large-diameter internal and external plastic-coated steel pipes
First, the material characteristics of large-diameter internal and external plastic-coated steel pipes: 1. Plastic coating: The inner and outer layers of large-diameter internal and external plastic-coated steel pipes are protected by plastic coatings. This kind of coating has good corrosion resi...Read more -

What are the effects of carbon and silicon in the chemical elements of seamless steel pipes on the properties of steel
The effects of carbon and silicon in the chemical elements of seamless steel pipes on the properties of steel are as follows: 1. Carbon (C): Carbon is the main element second only to iron in the steel used for seamless steel pipes. As the carbon content increases, the strength of the steel increa...Read more -
Explore the industrial details of large-diameter thick-walled seamless steel pipes
Large-diameter thick-walled seamless steel pipes are mainly reflected in: 1. Large diameter: It is generally believed that seamless steel pipes with diameters above 219 are large-diameter seamless pipes, those with diameters less than 76 are small-diameter seamless pipes, and those in the middle ...Read more -
The difference between ERW (straight seam resistance welded steel pipe) steel pipe and HFW (high frequency welded steel pipe) steel pipe
As the name suggests, resistance welding is a method in which pressure is applied through electrodes after the welding parts are assembled, and the resistance heat generated by current passing through the contact surface of the joint and adjacent areas is used for welding. High-frequency welding:...Read more
