GB/T 9948 12Cr5MoI seamless steel tube is a type of seamless steel tube that conforms to the GB/T 9948 standard and is made of 12Cr5MoI steel.
12Cr5MoI seamless steel tube is a type of steel tubing that is made from the 12Cr5MoI alloy, which is a low-alloy high-strength structural steel. This type of steel is known for its excellent mechanical properties, including high strength, good toughness, and wear resistance.
Seamless steel tubes are manufactured by a seamless process, which involves piercing a solid billet to create a hollow tube. This method ensures the absence of seams or welds in the tube, making it suitable for applications where a high level of integrity and strength is required.
The 12Cr5MoI seamless steel tube is commonly used in industries that require resistance to high-temperature and high-pressure conditions, such as in the manufacturing of boilers, superheaters, and pressure vessels. Its ability to withstand extreme conditions and its durability make it a preferred choice for these applications.
12Cr5MoI is a seamless steel tube that is annealed and used for processing petrochemical pipe fittings and connecting pipes of petroleum refineries. It is also used for petroleum cracking, sulfuric acid, and hydrochloric acid dew-point corrosion-resistant.
The chemical composition and mechanical properties of 12Cr5MoI steel are as follows:
The specific chemical composition of 12Cr5MoI steel is as follows:
The mechanical properties of 12Cr5MoI seamless steel tube are as follows:
12Cr5MoI seamless steel tubes are primarily used in petroleum cracking and high-pressure chemical fertilizer equipment. They are suitable for conveying fluids at high temperatures and pressures.
Ceramic lined pipe is made through self-propagating high-temperature synthesis (SHS) technique.
Cast basalt lined steel pipe is composed by lined with cast basalt pipe, outside steel pipe and cement mortar filling between the two layers.
Ceramic tile lined pipes have very uniform coating of specially formulated ceramic material that is affixed to the inner of the pipe.
The material of the rare earth alloy wear-resistant pipe is ZG40CrMnMoNiSiRe, which is also the grade of rare earth alloy steel.
Tubes Erosion Shields are used to protect boiler tubing from the highly erosive effects of high temperatures and pressures thereby greatly extending tube life.
The ASTM A213 T91 seamless tubes are primarily used for boiler, superheater, and heat-exchanger.
