welded pipe

Pre-galvanized steel pipe and hot-dip galvanized steel pipe are two common types of steel pipes. They are both treated with galvanizing process to improve the corrosion resistance and service life of steel pipes. Although both are galvanized steel pipes, there are obvious differences in production

During the use of industrial carbon steel pipes, color marking is usually used to distinguish different media, pressure levels and uses. These color markings can improve work efficiency, reduce the risk of misoperation, and provide a basis for rapid identification in emergency situations. The following

The following are some commonly used grades and related introductions of carbon steel pipes in the world, classified according to common standards and countries: 1. United States (ASTM/ASME standard) ASTM A106 Purpose: Seamless carbon steel pipes widely used in high temperature and high pressure environments.

Red plastic-coated fire fighting steel pipe is a steel pipe specially used in fire protection system. It has the characteristics of corrosion resistance, high temperature resistance and easy identification. It is widely used in automatic sprinkler fire extinguishing system, fire hydrant system, etc. The following

Welded steel pipe weld seam style and characteristics According to the weld seam form and processing technology, welded steel pipe is mainly divided into straight seam welded pipe, spiral welded pipe and other special weld seam forms (such as girth welding, spot welding). Different weld

Is there a difference between Steel Pipe and Steel Tube? In the fields of engineering, construction and industrial manufacturing, steel pipe and steel tube are often mentioned. Although the two are similar in appearance and material, and can be collectively referred to as steel pipes

Seamless steel pipes and welded pipes (including straight seam welded pipes and spiral welded pipes) have significant differences in manufacturing processes, performance, uses and costs. The following is a detailed comparison of the advantages and disadvantages of the two: Advantages of seamless steel pipe No

The caliber range of welded steel pipes is very wide. The specific caliber models vary according to different standards (such as national standard GB, American standard ASTM, European standard EN, etc.), but generally cover the following caliber classifications: 1. Nominal diameter (DN) Small diameter welded

Pickling 1. Use acid to remove impurities such as scale and rust on the surface of the steel pipe. After pickling, the surface of the steel pipe becomes smooth and suitable for further coating or plating. Sand blasting 1. Use high-speed sand flow to clean

The standards for welded steel pipes cover the respective specifications of different regions and countries to ensure the quality, safety and performance of the products. These standards are applied in major markets such as China, the United States, Europe and Japan. The following are common
