Industry Approvals
& Compliances

• Steam lines (high pressure applications over +450°F / +232°C

• Steam

• To industry standards

• Cryogenic transfer

• Liquified gas

• Conveying lines (cryogenic fluids, chemical transfer of liquids, gases and vapors)

• Wide temperature range -- -460°F (-273°C) to +1500°F (+816°C)
• High quality and excellent workmanship to meet the rigorous demands of extremes in service at competitive prices with quick deliveries
      --Machined bar stock end fittings; designed to mate with hose for proper weld techniques
      --Double-pass welding (TIG)
      --Custom fabrication available to meet customer specifications
• More corrugations per foot
• Greater flexibility than competing products of similar size
• Low force to bend; easier to install and disconnect
      --Flex-life extended
• Compensates for misalignment, facilitates movements/thermal expansion
      --Braid coverage engineered to contain the inner core under pressure and reduce possibility
       of squirm
• Absorbs vibration and deadens noise in rigid systems
• Vacuum tight
• Handles high pressures
• Corrosion resistant
• Non-aging/non-flammable

• Inner metal hose:
      --Annular corrugated close pitch hose
      --Profile:  parallel corrugations, omega shape close pitch
      --Made from butt-welded tubing
• Reinforcement:  Polypropylene braid
      --Each strand of large diameter (denier) polypropylene monofilament is twisted and
         subsequently twined prior to braiding
      --Tested for maximum abrasion and chemical resistance

Fittings 

• Any style using butt weld construction (TIG method)
      --NPT, FNTP, flange, J.I.C. compression, union, vacuum, sanitary, O-ring,  BSP, metric and DIN

• Select 316L or 304 stainless steel inner core, depending on the type of medium.

Corrosion potential 

• The corrosive nature of both the medium to be conveyed and the outside environment should be taken into account; the corrosive effects of many chemicals can be accelerated by higher temperatures. 
• If the material to be transferred is gaseous, flow rates should be specified, especially if velocity is to approach or exceed 180 feet per second. 
• Are the fittings to be of the same material?

Relationship of pressure rating, temperature and type of service 

• Operating pressures listed in the accompanying specifications chart (above) reflect a rating based on one braid reinforcement and a minimum safety ratio of 4:1, burst pressure to rated operation pressure. 
• Ratings are based on operating at ambient temperature -- 70°F (21°C). If your application exceeds this temperature, consult the temperature correction chart to calculate the adjusted pressure rating at your particular operation temperature.

Maximum service temperature 

• 316L stainless steel: +1500°F (+815°C) 
• 304 stainless steel: +850°F (+454°C)

• Maximum operating temperature:  700°F
• Maximum operating pressure:  200 PSIG 
• Computations:
       --Check specifications chart for minimum rated burst
          pressure for 1" CF04 - 2400
       --Check temperature correction factors chart for
          correction factor for 1" CF04 at 700°F = .70
       --Rated burst pressure:  2400 x .70 = 1680 PSIG
         (rated burst pressure at 700°F)
       --Safe operating pressure:  1680/4 = 420 PSIG
         (using 4:1 safety factor)
    
• Result
      --1" CF04 is rated at 420 PSIG MAWP, well in
        excess of the 200 PSI of the example operating
        environment.
