Product Description

Copper-Aluminium Bimetal Clad Pipe Tube
It is a new type of wear- resistant and corrosion-resistant pipe. Especially, its excellent wear-resistance and corrosion-resistance and high pressure resistance make bimetal clad steel pipe can be used under any pressure class. Inside layer and outer layer bonded very well by explosive welding, metallurgical bonding interlay ensures reliability. Bimetal clad steel pipe are widely used in oil field, chemical industry, electric power industry. With wider and wider applications, it brings us more economic, environmental, social benefit obviously.

The basic principle: the outer base metal is responsible for the pressure bearing and pipe supporting rigidly, the inner clad metal assume the role of corrosion resistance. Different carbon steel with different DN and WT are chosen as outer base pipe according to medium flow and pressure requirement. Galvanizing steel pipe, longitudinal welded pipe, spiral pipe, running pipe for conveying low medium pressure fluid, like seamless steel tube, high pressure boiler, seamless steel tube for petroleum cracking process and pipe line.
OD: φ20-φ1,020mm,WT: 2.5-50mm

Hardfacing layer information:

Hardness	HARDNESS TOLERANCES	Thickness tolerances	Bath depth	Welding direction
58-62HRC	-0/+1,5 HRC	-0/+1 mm	1-2mm	Lengthways of the plate

Clad pipe after hardfacing:
1- Thickness tolerances : -0/+1 mm  
2- Physical properties : resistant to abrasion and erosion till 800°C.  
3- Flatness tolerances : max. 3 mm/1000 mm.  
Chemical composition:

Cr	C	Si	Mn	others	Hardness
24-30%	4%-5%	0.5%-1.5%	0.5%-2.5%	Less than 2%	58-62HR

Austenitic-stainless steel, 304, 304L, 316, 316L, cooper base alloy, nickel base alloy, Hastelloy, titanium and titanium alloy, duplex stainless steel. Wall thickness of liner pipe is 0.3-4mm according to working life and welding technique.

Main parameter of bimetal clad pipe: bonding force, it means the combination level of internal and external pipes. It's the most important testing index for bimetal clad pipes.

The advantage of bimetal clad pipe compared with the general alloy pipe: the higher the price of general alloy, the more cost can be saved if substituting bimetal clad pipe for general alloy.

Applications of bimetal clad pipes
In the civil field: cold and hot water pipe, drinking water pipe, heating pipe, solar energy pump, ground source heat pump; water supply pipe and water distributing main pipe in civil architecture, air conditioning circulating pipe, water supply pipe in fine decorated high-grade commercial housing.
In the industry field: gathering pipeline for conveying oil and gas, oil-gas well drive pipe, sewage recycle pipe line, tube bundle in heat exchanger, demineralized water pipe, desulfuration pipe, etc. Metallurgy, sea water desalination, pharmaceutical chemicals, sewage treatment, new energy, and food process industry, etc.
