近年来在苏联Ⅰ级和Ⅱ级钢筋混凝土管(设计压力相应为15和10个大气压)以及混凝土和无压钢筋混凝土管的产量不断增加。使用这些管材代替钢管和铸铁管可以解决供应不足的金属并提高管道的耐久性。 OCT22000-76也规定了在输水干管中使用Ⅲ级压力管和低压管(设计压力相应为3和5个大气压)。压力输水管道对这种管子的需要量约为60～80％,然而在苏联尚未组织这类管材大规模的工业化生产。这种需要靠使用很贵的Ⅰ、Ⅱ级压力管及其等外品
In recent years, the output of Soviet Class I and II reinforced concrete pipes (design pressures corresponding to 15 and 10 atmospheres) and concrete and non-pressure reinforced concrete pipes have been increasing. Using these tubes instead of steel tubes and cast iron tubes can solve the problem of under-supplying metals and increase the durability of the tubes. OCT 22000-76 also specifies the use of Class III pressure and low pressure pipes in the water main (design pressures corresponding to 3 and 5 atmospheres). Pressure pipes require about 60 to 80% of this pipe. However, the Soviet Union has not organized large-scale industrial production of such pipes. This need depends on the use of expensive I and II pressure pipes and other external products.
