What are SS Hose Assemblies?
Stainless steel hose assemblies are essential for connecting fire protection piping to sprinkler heads in fire sprinkler systems. Manufactured at our advanced facility, our SS hose assemblies are versatile and suited for diverse applications such as chemicals, petroleum, superheated steam, liquefied gas, and cooling lines.
Our steel hose assemblies feature stainless steel convoluted hoses designed to absorb movement in rigid pipe systems, withstand extreme temperatures and radiant heat, accommodate misaligned pipework, and absorb lateral and angular movement. Available in grades like AISI 304, 316, and 321, these assemblies come with a variety of end connections, bore sizes, and lengths tailored to meet specific customer needs.

What Do We Offer?
We provide complete solutions for stainless steel hose assemblies, customized to meet your exact needs. Whether you require specific end connections or materials, we can deliver tailored flexible metal hose assemblies to suit any application.
Standard End Fitting SS Hose Assemblies
Selecting the right fittings for your application depends on matching them with the existing fittings in your system. Ensure that the hose fittings align with the type, size, and material of the mating fittings. It’s crucial to check that the fittings can handle the pressure, temperature, and chemical exposure of the media and environment.
Our fittings come in various materials, including stainless steel (SS-304, SS-316). We offer both male and female end fittings, as well as flange connections with fixed and floating options, compliant with DIN, ANSI, ASA, and IS standards.
Stainless Steel Hose Assemblies with Stripwound and Interlock Options
Our stripwound or interlock hoses are crafted by spirally winding a continuous metal strip, with interlocking edges to form a durable hose. Available in galvanized and stainless steel alloys, these hoses come with a directional flow liner to manage high-velocity fluid transfer.
Standard sizes range from 5/32″ in diameter, and we offer various sizes, lengths, and end fitting configurations. To prevent issues like abrasion and pressure drops due to turbulent flow—especially when fluid velocity exceeds 25 meters/second for liquids and 50 meters/second for gas—a flexible interlock liner is used.
Exhaust Steel Hose Assemblies
Exhaust hose assemblies are designed with strip wound metal hoses featuring polygonal or round cross-sections, providing robust performance for various applications. Our hoses come in square, interlock, and double interlocked profiles, with optional seals such as asbestos thread or copper wire, tailored to meet specific needs.
End fittings can be customized to suit your requirements and application. Whether for high-temperature exhaust systems or specialized industrial uses, our exhaust hose assemblies ensure reliable and efficient transfer of exhaust gas.
SS Hose Assemblies for Metal Expansion Joints
Metal expansion joints are essential for accommodating thermal movement in piping systems. Our stainless steel (SS) hose assemblies are designed to absorb these movements efficiently. Made from high-quality 304, 321, and 316 stainless steel, our expansion joints feature durable bellows and are available with various end fittings, including welding nipples, fixed flanges, and floating flanges.
We offer a wide range of standard pipe sizes starting from 2″ and customizable options for size, length, and end fitting configurations. Each unit can be tailored to meet specific requirements and special applications. Our SS hose assemblies ensure reliable performance and flexibility in handling thermal expansion and contraction.
Type of metal hose assemblies
Type of metal hose assemblies: Based on flexibility, the Annular corrugated hoses are categorized as follows according to ISO 10380-2003.
▣ Type #1: This type of hoses are highly flexible and are used for special applications where high flexibility and fatigue life is required. The cyclic life is a minimum 10,000 cycles when subjected to a short bend radius.
▣ Type #2: This type of hoses have moderate flexibility and are widely used in Industrial applications. The cyclic life is a minimum 10,000 cycles when subjected to a wide bend radius.
▣ Type #3: This type of hose has low flexibility and is suitable for static applications . The cyclic life is 30 cycles and mostly used unbraided.
