An impact-resistant sewer pipe is a sewer pipe used as underground pipe under non-pressure conditions. It is made from impact modifier and hard PVC resin. The impact-resistant sewer pipe is composed of the straight pipe, a general pipe type, which requires separate fittings for straight extension, the collar pipe (SRA) with a rubber ring inside, which does not need any additional pipe fittings for extension, and improved SRA pipe (R2 Type), which is a type of collar pipes with a tightening cap and increased coupling strength.
