304 Lined Carbon Steel 90 Degree Composite Elbow

304 lined carbon steel 90-degree composite elbow is a bi-metal clad pipe fitting with metallurgical bonding structure.The outer substrate is carbon steel,which provides sufficient mechanical strength,pressure resistance and structural rigidity.The inner surface is lined with 304 stainless steel cladding,directly contacting conveyed media to deliver excellent corrosion resistance.

The carbon steel base layer bears pipeline pressure and external load,while the 304 stainless steel lining prevents rust and corrosion from fluid medium.The two layers achieve tight metallurgical combination,avoiding separation,blistering or peeling under bending,welding and temperature variation.

This composite elbow is an economical substitute for solid 304 stainless steel elbows.It avoids the high cost of full alloy fittings and solves the corrosion problem of pure carbon steel elbows.It matches perfectly with 304 lined carbon steel bi-metal clad pipe for integrated pipeline construction.

Main Advantages

Cost-effective solution:Only the inner contact surface adopts 304 stainless steel,greatly reducing material cost compared with solid stainless steel elbow.

Reliable anti-corrosion performance:304 lining resists oxidation,fresh water,weak acid and organic medium corrosion.

Excellent mechanical property:Carbon steel outer layer ensures high pressure resistance,impact resistance and structural stability.

Convenient site construction:Compatible with conventional welding processes,consistent with supporting bi-metal clad pipe installation standards.

Good structural integrity:Metallurgical bonding interface withstands thermal cycling without lining detachment.

Application Scenarios

Water supply pipeline,sewage treatment,chemical medium transportation,food processing pipeline,power plant circulating water,general industrial fluid delivery.
