Bimetal Composite Pipe

Bimetal composite pipe is a high-performance composite pipeline material manufactured by metallurgical bonding of two different metal layers.It generally consists of an outer base pipe with high structural strength and an inner lining pipe with excellent corrosion or wear resistance.Through advanced composite forming processes,the inner and outer metal layers achieve tight metallurgical integration without separation under normal working conditions.

This product combines the mechanical advantages of carbon steel,alloy steel and the anti-corrosion,wear-resistant properties of stainless steel,duplex steel,copper,nickel alloy and other materials.It overcomes the defects of single metal pipes:ordinary carbon steel pipes are prone to corrosion,while solid alloy pipes cost excessively high.Compared with mechanically lined pipes,metallurgically bonded bimetal composite pipes feature reliable interface bonding,capable of withstanding bending,flanging,welding and thermal expansion without lining detachment.

Key Advantages

Balanced cost and performance:The base layer bears structural load,and the thin inner alloy lining provides medium protection,greatly cutting material costs versus solid alloy tubes.

Outstanding medium adaptability:Resists acid,alkali,salt water,oil and corrosive fluid erosion;wear-resistant grades serve solid-liquid mixed conveying.

Convenient construction:Compatible with conventional pipe welding,flange connection and hot working technologies,consistent with standard pipeline installation specifications.

Stable mechanical performance:Good tensile strength,pressure resistance and impact resistance,suitable for high-pressure and temperature-variable working environments.
