Putnam, CT-消防设备和水运输解决方案的制造商Kochek Company,LLC报告说,其10英尺和20英尺的PVC抽吸软管经过严格测试,并发现其性能没有泄漏,抑制作用或脱钩,并且即使在此之后也表现出了出色的线圈记忆压力12小时。科切克的PVC抽吸软管专门为消防市场设计,并符合公司专有的消防级规格。188金博网网址多少所有尺寸为2.5英寸及更大的Kochek PVC吸管均符合NFPA。
测试性能
When filled with over 14 gallons of water and hung vertically by the long handles of the female coupling for 12 hours, Kochek’s 10-foot PVC suction hose maintained constant pressure at the hose end. It performed without leaks and with no signs of decoupling. Stretching six inches when full, the hose returned to original length once water was removed. After an additional 12-hour test repositioned for a 90-degree attachment that simulates truck connection, vacuum was maintained when the petcock valve was opened and equalized, and no leaks or decoupling occurred.

Kochek的20英尺PVC抽吸软管充满了近30加仑的水,重复了10英尺软管进行的阳性测试结果。在压力下,它在压力下延伸至12英寸,在空空时,它的原始长度一直延伸至原始长度。Kochek建议使用45度或90度肘部支撑其20英尺软管的软管端,同时在90度附着,以减轻潜在的流量限制。
满足NFPA 1961年的所有要求,Kochek的PVC吸管即使在极端温度下也可以提供可靠的,无助的操作,从而保持了从150°F到-40°F的灵活性。内置紫外线防护量后,它将保持优质的壁厚从3英寸到6英寸的ID,并具有光滑的孔,以无限制地流动。Kochek PVC抽软管以结束耦合的形式出售,可以按常规和定制长度订购。所有Kochek产品均受针对制造缺陷的五年保修。
