Product specification and description
Galvanized steel pipe is divided into cold galvanized steel pipe and hot galvanized steel pipe two kinds. Cold galvanized steel pipes have been banned, and hot galvanized steel pipes are heated and molten zinc liquid covered on the surface of the steel pipe to form a coating, and then cooled and solidified. The galvanized steel pipe has the characteristics of thick galvanized layer, smooth surface, strong adhesion, good corrosion resistance and long service life.
The manufacturing process of galvanized steel pipe includes the following steps: First, the steel pipe is pickled to remove the oxide film on the surface; Then hot dip galvanizing or electrogalvanizing; Finally, it is cooled and solidified. After these steps, the galvanized steel pipe is manufactured.
Galvanized steel pipe has a wide range of applications. In the construction field, galvanized steel pipe can be used for building water supply, drainage, heating and other pipeline systems. In the medical field, galvanized steel pipes can be used for the production and processing of medical devices. In the field of aviation, galvanized steel pipes can be used in the manufacture of aircraft, rockets and other aircraft. In the field of mechanical manufacturing, galvanized steel pipes can be used for the manufacture and processing of mechanical parts. In the field of shipbuilding, galvanized steel pipes can be used for the construction and maintenance of ships. In the field of light industry, galvanized steel pipes can be used for the production and processing of light industrial products. In the agricultural sector, galvanized steel pipes can be used for the construction and maintenance of irrigation systems.
In short, galvanized steel pipe is a steel pipe that has been specially treated to enhance its corrosion resistance and is widely used in various fields.
Our inspection of steel pipes generally includes: inspection of geometric size and surface quality: inspection of chemical composition, mechanical properties, technological properties, inspection of high-low tissue: non-destructive testing: inspection of some special properties and length measurement and weighing.
(1) Check the geometric size of the steel pipe
The outer diameter, wall thickness, bending degree and length of the steel pipe are checked on the inspection table with external calipers, micrometers, bending degree and length winding.
Sometimes, the outer diameter, wall thickness and length are also continuously tested by automatic size detection devices (such as automatic diameter measurement, thickness measurement, length measurement devices). For OCTG steel pipe also need to check the thread parameters.
(2) Check the inner and outer surfaces of the steel pipe
We generally use visual inspection for internal and external surface inspection, and in addition to visual inspection, the internal surface is also inspected by reflection prism. Some special purpose steel pipes also require non-destructive testing, including eddy current, magnetic leakage, ultrasonic, magnetic particle testing, etc., to check the quality of the inner and outer surface of the steel pipe.
(3) Mechanical properties and process performance inspection
In order to verify that the mechanical properties of the steel pipe meet the requirements of the standard, we need to conduct mechanical properties inspection on the steel pipe sampling.
The test of mechanical properties mainly includes tensile strength, yield strength, elongation, impact work, etc. The process performance test mainly includes flattening test, flaring test, water pressure test, flange test, cold bending test, perforating test and so on. These inspection items are selected according to the different standards and the difference in the use of the steel pipe.
(4) Non-destructive inspection
Our non-destructive testing methods include: magnetic leakage testing, ultrasonic testing, eddy current and fluorescent magnetic particle testing, ultrasonic spectrum analysis testing, ultrasonic imaging testing and ultrasonic high temperature testing
Material introduction
Galvanized steel is a kind of steel after galvanized processing, which can effectively prevent steel corrosion and rust, thereby extending the service life of steel.
The coating of galvanized steel has strong toughness and can withstand mechanical damage during transportation and use. Galvanized steel is mainly used in the construction and manufacturing industry, because of its corrosion resistance, high strength, good durability, is widely used in a variety of building structures and mechanical equipment.
The coating of galvanized steel is usually divided into two kinds: electric galvanizing and hot-dip galvanizing, of which hot-dip galvanizing has a better anti-corrosion effect. Galvanized steel is often used in building external walls, glass curtain walls, marble curtain walls and other columns and stress materials, or used in outdoor telecommunications towers, highways and other open-air buildings.
