NL2540: ContiTech 250 CB Chlorobutyl Steam Hose

ContiTech CB Steam is a proven, safe, reliable, heavy duty steam hose suitable up to 250 psi @ 218°C (425°F). Its wrapped cover provides superior abrasion resistance and handling integrity while its chlorobutyl tube provides excellent heat aging resistance. Together, these two properties ensure a long service life, even in rugged environments. It is commonly used in construction, foundries, steel mills, shipyards, chemical plants, and refineries where severe abrasion can be expected and where a durable, safe, and reliable hose is required; for short jumpers we suggest using stainless braided hose assemblies. NL2540 has a 10:1 safety factor. We have listed some of our popular assemblies that can be made up from our bulk inventory; each assembly is coupled with premium Boss Ground Joint couplings (see our ‘Fittings Section’ for more information). Long, continuous lengths of EPDM steam hose are also available on special request (NL2562 EPDM Series). For short jumper steam assemblies under 10ft, consider using stainless steel assemblies.

Construction: Tube: Black chlorobutyl rubber (2-1/2″ & 3″ is EPDM). Cover: Wrapped, red Pyrosyn rubber (pin pricked to prevent blistering). Reinforcement: Wire braids (1/2″ has one braid, 3/4″ and up has 2 braids).

Typical Fittings: Interlocking bolt type coupling (ground joints). Interlocking bolt clamps MUST be checked and retightened before EACH use due to the cold flow/setting characteristics of rubber hose! DO NOT use universals, camlocks, any gasket type fittings, punch clamps, pinch clamps, crimp sleeves or gear clamps with steam hose. We DO NOT recommend the use of “Imported” Ground Joint Couplings and clamps for Steam, Critical, Toxic, combustible fluids, or in cyclic conditions involving temperature or pressure. “Imported” Ground Joint Couplings and Clamps often do not meet stringent material or tolerance guidelines for critical applications. We ONLY RECOMMEND Dixon Boss or Campbell Viton Seal Ground Joint Couplings and Clamps for use with steam or critical applications – see safety warning information. Testing & certification.

Temperature Range: -40°C (-40°F) to +218.3°C (425°F)

Detail Comments: For long continuous lengths up to 400′, refer to our NL2562-xxx EPDM Series.
