Metallurgical Complex Dual(multi)Metal Tube & Pipe
Metallurgical complex dual(multi) metal tube and pipe
For the strong corrosion,high wear,high working pressure of the fluid enviroment,the use of pipes,usually of high quality stainless steel or high alloy content of the seamless steel tubes,these tubes add a large number of precious metals because of their prices and generally a few general seamless steel pipe times or several times.over the years,pipe users and manufacturers have been trying to find through different metal compound,thereby to obtain a use meets harsh environment,but also inexpensive,high-performance composite pipe.
At present,although there are such a bi-metallic composite pipe market,but because only a molding process is a simple mechanical compound (explosion forming,bulge forming,drawing,rolling,etc.),internal and external layer of metal is just a simple mechanical interlocking ,its fatal problem is combination of macro-level there is space,it is difficult to meet user requirements.
Metallurgical composite double (multi)metal in recent years,Manusteelcn Seamless Steel Pipe Co,Ltd., Manusteelcn Ductile Lron Pipes AG and Beijing University of Science and Technology to achieve the combined strengths of technology developed for new products. the new metallurgical complex pairs (multi)metal pipe is unique in that:it is the primary industrial material and high-tech combination of the metallurgical process,using centrifugal casting tube by extrusive pipe can be a general carbon steel and stainless steel (e.g.,20# steel +304),
general stainless steel and high-quality stainless steel (e.g, 304 +316 L) can be any of steel and nickel, chromium,molybdenum alloy composite;may also require the user to achieve a variety of multi-layer composite metal.
This completely new type of metallurgical composite pipe can be widely used in petroleum, chemical,marine platforms,and other strong corrosive environment,but also through the inner layer of composite wear-resistant metals,to meet the pulverized coal power plants, mining slag and tail high pulp conveyor Wear work environmental requirements.

Technology characteristics

Combind with the traditional bi-metal composite pipe machinery compared to the centrifugal casting + extrusion + cold produced in pairs(multi)metal metallurgical production of composite pipes have a greater advantage.Centrifugal casting process using double-metal composite pipe production
With the incomparable advantage of the traditional process,mainly in:
(1)The traditional techique of double metal composite pipe production are combined with mechanical means,while the centrifugal casting technique is used in the liquid layer materials,a combination,so do the real purpose of metallurgical bonding.
(2)The centrifugal casting process is to make molten steel ie much higher than conventional gravity casting a few times under the conditions of coagulation,well-cast tube solve the problem within the loose,the metal density is high;the slag, exhaust effect Well, gas and inclusion content is much better than(the same netallurgical condition of)traditional craftsmanship.
(3)Centrifugal slab the size of high precision, uniforn wall thickness, in order to follow the dimensional accuracy or processer products provides a strong guarantee.
(4)The centrifugal casting process for small-volume,multi-species multi-standard,high quality, high value-added steel pipe production with high flexibility.
(5)For pairs of metal composite pipe can be flexible to change the primary and complex layers of material and thickness to meet the purposes and needs of different industries.

Composite pipe has a good ductility, as well as higher than the mechanical bonding strength of composite materials, to facilitate the realization of conventional reprocessing.
Corrosion-resistant and wear-resistant ability

1.Chooseing the composite materials with different can access to excellent ability to resistant corrosion or wear harsh environment to extend the service life of stell pipe.
2.If there is chloride ion stress corrosion cracking generated crack will encounter substrates stopped, Excellent corrosion resistance of alloyed interfance is still to make the pipe very safe.
