6" steel butt welding corrugated flexible metal bellow hose

6" butt welding corrugated flexible metal bellow hose is widely used in areas like heating ,ventilation,conditioning systems,irons and steel industry, chemical and petrochemical facilities,oil and gas refineries,chemistry and food industries,aircraft and ship construction facilities.
Connection welding tube: Stainless steel SS304/SS316/SS321
Annular Bellow:SS304/SS316L/SS321
Operating temperature: -196~+420℃
Operating pressure: 1.0~25Mpa

Fustar butt welding flexible metal hose assemblies are designed for applications where chemicals and temperature extremes,either from media or atmosphere,are present.Factory welded and ready to install,these Fustar butt welding flexible metal bellow hose assemblies are leak-free,full vacuum hose solutions. 

Fustar butt welding corrugated bellow hoses are constructed with a hydroformed corrugated stainless steel core tube.Hydroforming,which utilizes high pressure water to form the corrugations,minimizes residual stress in the metal and maintains a consistent tube wall thickness throughout the corrugated bellow hoses. 

Any butt welding flexible metal hose assembly is only as goods as its weakest link.In the case of a corrugated flexible metal bellow hose assembly,the weakest link can be the welding process.The proprietary methods of seam and butt welding,as well as fitting attachment,utilized in Fustar assemblies are second to none and yield a consistent,reliable,leak-free connection.

Butt Welding Corrugated Flexible Metal Bellow Hose Features 
· Excellent chemical resistance 

· Operates in high temperatures 

· Sizes 1/4" I.D. up to 24"I.D. 

· Hydroformed design yields a uniform wall thickness,promoting even distribution of stress during flexing and reduces concentrated residual stress

· Full Vacuum - Maintains its shape under full vacuum,other hose types collapse 

· Fire safety - Maintains its integrity up to 450℃

· Zero permeation 

· Leak-free fitting weld connection
