Product specification and description
Chemical composition: Cu:99.90;P:0.004-0.012
Mechanical properties: tensile strength σ B (MPa) : 215 ~ 271; Elongation δ10 (%) : ≥25; Hardness: 55 ~ 100HV
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
Copper is a metallic element with the symbol Cu, atomic number 29, and atomic weight 63.546. It belongs to Group IB metal.
Copper is the metal with the highest thermal and electrical conductivity and is the most commonly used material in cables and electrical and electronic components. Copper is also used as a building material and can be made into a wide variety of alloys.
The application areas of copper include:
Electronic industry: Copper is one of the important materials for electronic components and has excellent conductive properties. Copper wire is widely used in power transmission, wires and cables and other fields. In addition, copper is also used in the manufacturing of electronic equipment, such as circuit boards, semiconductor devices, etc.
Construction and building decoration fields: Copper has corrosion resistance and good plasticity, so it is often used in building facades, roofs, interior decoration projects, doors and windows, etc. Copper also has antibacterial properties, so it is also commonly used in medical facilities and public spaces to make door handles, touch panels, and more.
Machinery manufacturing field: Because copper has good toughness and wear resistance, it is often used in the manufacture of bearings, gears, dies, pressure sensors, instruments, etc. Especially in the fields of aerospace, automobile and shipbuilding, copper materials also have important application value.
Transportation: Copper is mainly used in the shipping industry. In warships and merchant ships, copper and copper alloys are generally used as aluminum bronze propellers, bolts, condenser tubes, rivets, copper-containing coating paint, etc.
Energy and chemical industry: The application of copper in the energy industry is mainly for heat dissipation and condensation, in the form of copper tubes. Copper and many copper alloys in the petrochemical industry are mainly used in manufacturing contact with corrosive media, such as various containers, piping systems, filters, pumps and valves, various evaporators, heat exchangers and condensers, etc.
Chemical and petroleum fields: Copper is also widely used in the chemical and petroleum fields, such as manufacturing pipes, valves, heat exchangers, pumps, etc.
Electric power field: Copper is one of the most important transmission materials in the electric power field. It is used not only to make wires and cables, but also to make electrical equipment such as transformers and motors.
Environmental protection field: Copper has excellent corrosion resistance and stability, so it can be used to manufacture environmental protection equipment, such as wastewater treatment equipment, air purification equipment, etc.
