What is the difference between alloy pipe and carbon steel pipe?

The production process of alloy pipe and seamless carbon steel pipe is different

1. Alloy pipe is a kind of seamless steel pipe, and its performance is much higher than that of ordinary seamless steel pipe. Alloy pipes are divided into structural seamless pipes and high-pressure heat-resistant alloy pipes. Mainly different from the alloy pipe and its industry production standard, the annealing and tempering of the alloy pipe changes its mechanical properties. Meet the required processing conditions. Its performance is higher than that of ordinary seamless steel pipes. The chemical composition of the alloy tube contains more Cr, which has the characteristics of high temperature resistance, low temperature resistance and corrosion resistance.
2. Carbon steel pipe is made of steel ingot or solid round steel through perforation to make capillary tube, and then hot rolled, cold rolled or cold drawn. The raw material of carbon steel pipe is round tube billet, and the round tube embryo should be cut into a long billet about 1 meter long by a cutting machine, and transported to the furnace by a conveyor belt. The steel billet is sent into the furnace for heating, and the temperature is about 1200 degrees Celsius. The fuel is hydrogen or acetylene. Furnace temperature control is a key issue. After the round tube is out of the furnace, it must be pierced with a pressure piercer.

Alloy pipes contain elements different from carbon steel pipes
Alloy pipes contain more other elements than carbon steel pipes.
1. Alloy pipe refers to steel containing silicon and manganese as alloying elements or deoxidizing elements, as well as other alloying elements, and some also contain certain non-metallic elements. According to the content of alloy elements in the steel pipe, it can be divided into low alloy steel pipe, medium alloy steel pipe and high alloy steel pipe.
2. Carbon steel pipe mainly refers to the steel whose mechanical properties depend on the carbon content in the steel pipe. Generally, a large amount of alloy elements are not added, and it is sometimes called ordinary carbon steel pipe.

The chemical properties of alloy pipe and carbon steel pipe are different
1. Carbon steel pipe contains a certain amount of carbon, the greater the hardness, the higher the strength, but the lower the plasticity.
2. Add other elements, such as manganese, nickel, chromium, silicon, etc., to the alloy tube to obtain different mechanical and chemical properties to achieve better use requirements.

Comparison of the characteristics of alloy pipe and carbon steel pipe
1. Characteristics of carbon steel
① Easy to smelt and process
②Low cost and wide application
③Heat treatment can be strengthened
④ Poor tempering stability
⑤ Low economic penetration
⑥Basic phase strength is low, toughness is poor, can not meet special performance requirements
2. Characteristics of alloy steel
① Smelting and processing are difficult
②High cost
③High tempering stability
④ High hardenability
⑤ The basic phase has high strength and good toughness, which can meet special performance requirements
