PRESSURE RESISTANT PIPING SYSTEM
PROBLEM TO BE SOLVED: To provide a pressure resistant piping system, which: is superior in workability, corrosion resistance and earthquake resistance; and prevents excess pressure loss; still assuring pressure resistance.SOLUTION: A pressure resistant piping system in this invention comprises pipes and couplers, of which the main composition is polyolefin resin. The coupling comprises: a connection part which is connected with at least either of a pipe or another coupler; and a link part which, having the wall thickness thinner than that of the pipe, is linked to the connection part. Furthermore, where the link part's wall thickness is t, the outer diameter is D and the length along the pipe axis is L, the following formula (i) and (ii) are true: (i) D/t≥9, (ii) L/D≤0.7D.SELECTED DRAWING: Figure 1
【課題】施工性、耐食性および耐震性に優れ、かつ、圧力損失の過大を防止しつつ耐圧性を確保する耐圧配管システムを提供する。【解決手段】本発明の耐圧配管システムは、ポリオレフィン系樹脂を主成分として構成される管および継手を含む。継手は、管および他の継手の少なくともいずれかと接続されている接続部と、当該接続部に連設されかつ管よりも肉薄の連設部と、を含む。さらに、連設部の肉厚をｔ、外径をＤ、軸心方向長さをＬとした場合、次の（i）および（ii）の関係：（i）Ｄ／ｔ≧９，（ii）Ｌ／Ｄ≦０．７Ｄ を満たす。【選択図】図１
