Carbon steel clad copper steel tube designed for heat exchanger application




This product is produced with the most global-advanced technology, through clad molding technology, and form the metallurgical grade of bimetallic copper clad tube. This product is light, has good thermal conductivity and good toughness at low temperature. It not only has the high strength like general metal but also owns the property of copper pipe, such as good formability, good workability. Besides, it is not easy to crack, break and obtain definite ability of frost resisting and impact resistance. This product can be widely used to replace the industrial and civil pure copper pipe, which means significant economic and social benefits, even represents the trend of technology replacement in the global market.

Performance characteristics

1.       Adhesion strength between layers is more than 140MPa
The copper clad pipe whose outer material is pressure resistant metal pipe and inner material is T2 copper seamless steel pipe. Combine these two materials with special processing technology which can not only resist corrosion, but also resist high temperature. The most important point is that its adhesion strength is 6 times as traditional clad pipe, it’s up to 140 MPa, and it solves the century problem of bad adhesion strength of traditional copper clad pipe absolutely.

2.       Excellent machining property
Copper Clad pipe has excellent mechanical property, high strength and perfect toughness.

3.       Excellent antifatigue ability
The product can resist high temperature because its outer and inner materials are metal, and the coefficient of heat expansion and contraction of these two metals are close, so the intermediate layer of clad pipe can not be destroyed under the condition of great temperature change. The pipe is still intact through cyclic experiment from normal temperature to 500℃.

4.       Excellent anticorrosion ability
Copper clad pipe has excellent anticorrosion ability, like crevice corrosion, point corrosion and stress corrosion cracking.

Problems of mechanical composite pipe

图片
1.Insufficient bonding strength Because there is no metallurgical bonding interface between the two metals, the bonding strength is low, generally 0.2-0.3mpa.It is easy to peel off the inner pipe due to insufficient bonding strength. 2.Poor sealing of end bevel The end bevel treatment of the mechanical composite pipe is a very key link. If the end seal is not good, it will not only lead to the peeling of the inner pipe and the outer pipe, but also affect the field butt welding. The most commonly used end treatment is seal welding and overlay welding. The welding consumables of seal welding technology are less and relatively cheap. Although it has many years of experience and is mature, its stability is relatively cheap, and the requirements for field butt welding are high, which is greatly affected by the welding level of welders. The welding consumables of overlay welding are more and the cost is more expensive ， but it has good stability and high comprehensive safety. 3.Thermal coll...

Material Selection basis of corrosion-resistant alloy pure material (corrosion mechanism of natural Gas Field)

According to NACE MR0175, the development and production environment of natural gas field can be divided into acidic environment and sweet environment. The acidic environment contains H 2 S and H 2 S partial pressure is greater than 0.03mpa. The sweet environment contains CO2 and Cl-, but does not contain H 2 S or H 2 S partial pressure is lower than 0.03mpa. Corrosion mechanism in acidic environment Corrosion mechanism in acidic environment H 2 S                     H +  +  HS - HS -                      H +  +  S 2- 2H + + Fe            Fe 2+  +  H 2 ↑ Therefore, in acidic environment, in addition to uniform corrosion and local corrosion on the surface of pipes, a series of metal ...

Advantages of bimetal metallurgical clad pipe

  u   Taking 316L as an example, its yield strength should be greater than or equal to 207Mpa which is specified in API specification 5LC, but still lower than that of ordinary pipeline steel. Therefore, in order to bear pressure, it is necessary to increase the wall thickness, resulting in a substantial increase in material costs. u   Therefore, the bimetal clad pipe is adopted by the oil industry, on the one hand, is forced by the environment, on the other hand, it also has its own unique technical advantages. u   Bimetallic clad pipe combines two advantages: high strength of base pipe and corrosion resistance of lining pipe. Compared with carbon steel and corrosion resistant alloy, bimetallic clad pipe has excellent performance and high cost performance. u   Since 1991, it has been widely used after decades of development. It has also been widely recognized in the petroleum product transportation and refining industry, and the American Petroleum Institute (AP...
