Cylinders for fire fighting equipment Designed for high-pressure storage and breathing extinguishant: carbon dioxide, insulating gas, nitrogen, argon and mixes, also chladone and his pollution free substitutes and apply in different sprinklers.Specification: BK-6601-400 TUCertificate: POCC RU.MT23.B00997 dated 02.04.2004. Cylinders for fire fighting equipment Physically cylinder is a steel hermetical liner with egg ends and mantle rings.There is a supporting neck with a carving for connection to sprinkler devices on a bottom of cylinder.Neck"s carving may be produced W27,8 GOST9909, M 36x2, M72x2 or another dimention-type according to GOST 8,724.Cylinders operating at pressure Pw=5.8 MPa (60 kgf/sq cm) may be produced in two variants:1. Cylinder is steel-made and braided with high-strength glass fiber (lightly built).2. Cylinder is steel-made without glass fiber braiding. Cylinders operating at pressure Pw=14.7 MPa (150 kgf/sq cm) and 7.8 MPa (80 kgf/sq cm) are produced only with glass fiber braiding.Cylinders are steel-made: Breaking point = 120 +- 10 kgf/sq mm. Yield point more then 100 kgf/sq mm. Reinforcing material is a high-strength glass fiber impregnated with sticker based on epoxy. The breaking strength of glass fiber is higher than 140 kgf/sq mm.Cylinder"s inside has underseal, which protect metal against corrosion. Cylinder"s facing are paint coated according to technical specifications BK-6601-400TS.Each cylinder is passed through the strength tests and leakage tests according to technical specifications BK-6601-400TU.Production technique guarantees: Functioning"s quantity (discharging-refueling) is 30; Service life period until first re-examination (including shelf life in storage rooms) is 15 years; Shelf life in storage rooms is 2 years; Exploitation at temperature condition -50C +50C and performance «o» category one according to GOST 15150-69. The sample of cylinder convention for order:Cylinder for sprinkler BK 80-150, BK-6601-400TU where:BK - production type;80 - capacity (L);150 - working pressure kgf/sq cm.
