API Spec 5L is an international standard that specifies the manufacturing requirements for two product specification grades (PSL 1 and PSL 2) of seamless and welded steel pipes used in pipeline transportation systems in the oil and gas industry.
API is an acronym for the American Petroleum Institute and is considered the most authoritative and comprehensive principle in the oil and gas industry. API 5B and API 5CT are mainly used for oil casing. API 5CT oil casing can be divided into seamless steel pipe and welded steel pipe, welded steel pipe mainly refers to the straight seam steel pipe, large diameter oil casing is generally submerged arc welding straight seam steel pipe.
A192 Seamless Carbon Steel Pipe
ASTM A192 is the same as ASME SA-192 and is the standard specification covering seamless carbon steel boiler and superheater tubes of minimum wall thickness for high pressure service.
C11000/T2 is pure copper, also known as copper, copper has good electrical conductivity, thermal conductivity, corrosion resistance and processing performance, can be welded and brazed. Contains less impurities to reduce electrical conductivity, thermal conductivity, trace oxygen has little effect on electrical conductivity, thermal conductivity and processing properties, but it is easy to cause "hydrogen disease". It is not suitable for processing (annealing, welding, etc.) and use in a reducing atmosphere at high temperature (such as> 370 ℃).
C10100/TU2C10100 oxygen-free copper cold and hot workability are excellent. Good forgeability. It can be used as a bus bar, waveguide, electron tube lead-in line and anode, vacuum seal, transistor components, speed control tube, microwave tube, rectifier.
C10200/TU1 is a high-purity, oxygen-free, phosphorus-free deoxidized copper in vacuum without evaporating elements. It has high electrical and thermal conductivity, good welding performance and excellent welding performance attributes. It has excellent hot and cold forming properties, and has good compression resistance and corrosion resistance, especially in the atmosphere, due to the good adhesion of the oxide layer.
C12000/TP1 has good welding performance and cold bending performance, generally has no "hydrogen disease" tendency, can be processed and used in reducing atmosphere, but should not be processed and used in oxidizing atmosphere, mainly for pipe application, but also for plate, belt or bar and line supply. Used as gasoline or gas transmission pipe, drain pipe, condenser pipe, mine pipe, condenser, evaporator, heat exchanger, train parts.
