welded pipe

There are several common surface treatment methods for steel pipes. The process, characteristics and uses of each treatment method are as follows: 1. Hot-dip galvanizing - Process: Immerse the steel pipe in molten zinc liquid to make the zinc adhere to the surface to form

Carbon steel pipe elbows are connectors used to change the direction of pipeline fluids and are commonly found in pipeline systems in industries such as petroleum, natural gas, chemical, and electric power. Elbows are classified into three basic types: 45°, 90°, and 180°. Special angles

Spiral welded pipe is a common type of steel pipe, and spiral welding technology is used in its manufacturing process. Spiral welded pipe has good strength and pressure resistance due to its unique structural characteristics and manufacturing process, and is widely used in fields such

High-pressure boiler tubes are key components used in boiler systems and are subject to high-temperature and high-pressure working environments, so their performance requirements are extremely strict. Among the many types of boiler tubes, seamless steel tubes are widely used in the manufacture of high-pressure boiler

Oil and gas line pipes are steel pipes specially used for transporting fluids such as oil and natural gas. As a key component for oil and gas transportation, it not only needs to withstand high pressure, corrosion, and low temperature, but also must meet the

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
