Alloy pipe VS carbon steel pipe

The production process of alloy pipe and 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 production standard of alloy pipe and its industry, the annealing and tempering of 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 alloy pipes contains more Cr, and it has 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 for carbon steel pipe is round tube billet, and the round tube embryo should be cut by cutting machine to grow billets with a length of about 1 meter, and transported to the furnace by conveyor belt. Billet is fed into the furnace to heat, the temperature is about 1200 degrees Celsius. The fuel is hydrogen or acetylene. The temperature control in the furnace is a key issue. After the round tube is out of the furnace, it must be pierced by a pressure piercer.

Alloy pipes contain different elements from carbon steel pipes
Alloy pipes contain more other elements than carbon steel pipes.
1. Alloy pipe refers to steel that contains not only silicon and manganese as alloying elements or deoxidizing elements, but also 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, and generally does not add a large amount of alloying elements, 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. Other elements, such as manganese, nickel, chromium, silicon, etc., are added 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
①Easy smelting and processing
②Low cost, wide application
③Heat treatment can be strengthened
④ Poor tempering stability
⑤Poor economic penetration
⑥Basic phase strength is low, poor toughness can not meet special performance requirements
2. Characteristics of alloy steel
① Difficulty in smelting and processing
②High cost
③High tempering stability
④High hardenability
⑤ The basic phase has high strength and good toughness, which can meet special performance requirements
