High Temperature and Cryogenic Composite Hose

Whether in high-temperature hot oil loading and unloading areas or in extremely cold chemical sites at tens of degrees below zero, ambient temperature directly affects the reliability and service life of hoses. Ordinary hoses are prone to softening and delamination at high temperatures, and hardening and cracking at low temperatures. Strongflex’s high-temperature and cryogenic composite hoses are designed to meet these challenges, providing a safer and longer-lasting solution for your chemical and fuel transfers through a multi-layered composite structure and specialized temperature-resistant materials.

SSTP Composite Hose | High Temperature

Construction:
Inner Wire: Stainless Steel 316L(S)
Outer Wire:Stainless Steel 316L(S)
Inner Lining:PTFE/Fiber Glass (TP)
Cover:PVC Coated Polyester Cloth
Standard::EN 13765:2010
Temperature Range: -30℃~+240℃
Safety factor:4:1
Vacuum:0.9 bar
Application: The hose is a composite of PP, PTFE and glass fiber, and can withstand temperatures of 240°C without losing its flexibility. Because both the inner and outer spirals are made of 316L stainless steel, it can be used in the most extreme conditions and corrosive environments. Due to its lightness, it is a substitute for heavy rubber hoses, such as conveying hot air, hot oil, etc., for loading/unloading tank trucks, diesel trucks, vegetable oil and even heavy marine applications.

SGTP Composite Hose | High Temperature

Construction:
Inner Wire:Stainless Steel 316L(S)
Outer Wire:Galvanized Steel 316L(G)
Inner Lining:PTFE/Fiber Glass (TP)

Cover:PVC Coated Polyester Cloth
Standard:EN 13765:2010
Temperature Range:-30℃~+240℃
Safety factor:4:1
Vacuum:0.9 bar
Application: SGTP is a composite hose made of PP, PTFE, and fiberglass. It can withstand temperatures up to 240°C without losing its flexibility. Because both the inner and outer spirals are constructed of 316L stainless steel, it can be used in exterior or non-corrosive environments. Its lightweight design makes it a suitable alternative to heavy rubber hoses for conveying hot air, hot oil, and other applications, such as loading and unloading tank trucks, diesel trucks, vegetable oil trucks, and even heavy-duty marine applications.

GGTP Composite Hose | High Temperature

Construction:
Inner Wire: Galvanized Steel (G)
Outer Wire:Galvanized Steel (G)
Inner Lining:PTFE/Fiber Glass(TP)
Cover:PVC Coated Polyester Cloth
Standard: :EN 13765:2010
Temperature Range:-30℃~+200℃
Safety factor:4:1
Vacuum:0.9 bar
Application: GGTP is a hose made of PP, PTFE and glass fiber. It can withstand high temperatures of 200°C without losing its flexibility. Since its internal and external spirals are made of stainless steel 316L, it can be used in external or non-corrosive environments. Since its internal and external spirals are made of galvanized carbon steel wire, it is the most economical product. It can be used for conveying hot air, hot oil, etc., for loading/unloading tank trucks, diesel trucks, vegetable oil and even heavy marine applications.

Cryogenic Composite Hose

High Temperature and Cryogenic  Composite Hoses: Usage Precautions and Maintenance Guidelines

Before use, carefully inspect the composite hose and connectors for integrity, ensuring there are no bulges, damage, scratches, or cracks. Check the spiral wires and connectors for rust, looseness, or breakage.

When installing the hose, avoid twisting to prevent misalignment or breakage of the multi-layer film. Avoid excessive bending. When transporting fuels or flammable chemicals, grounding is essential, and the spiral wires must be connected to the system ground.

During use, do not exceed the hose’s rated temperature and pressure. For high or low temperature environments, select the appropriate high-temperature or low-temperature composite hose. If working in corrosive or humid environments, stainless steel should be used for the spiral wires and connectors whenever possible.

When moving the hose, do not drag it on rough surfaces to prevent abrasion of the outer layer. Avoid flattening the hose when transporting heavy chemicals.

Store the cryogenic composite hose in a cool, dry place between -15°C and 40°C, avoiding direct sunlight. If the hose has been stored in extremely cold environments, place it in a warmer environment for half an hour before use to allow the material to regain its flexibility.

After operation in low-temperature environments, drain the fluid promptly to prevent freezing and expansion leading to cracking. If working in low-temperature environments for extended periods, consider adding an insulation sleeve or fabric protective cover.
