E hoʻomaopopo mua kākou i ka pōkole o ka radius lōʻihi a me ka radius pōkole.

Kuʻekuʻe kila kuhiliʻole lōʻihi:LR/EL/1.5D;

Pōkole radius kuʻekuʻe lima kila:SR/ES/1D;

ʻO ka radius i ʻōlelo ʻia ma ʻaneʻi e pili ana i ka radius kuʻekuʻe o ka kuʻekuʻe kila kila. ʻO ka radius kuʻekuʻe lōʻihi e pili ana i kona radius o ka curvature e like me 1.5 manawa o ke anawaena o waho o ka paipu, ʻo ia hoʻi, R=1.5D. ʻO ke kuʻekuʻe lima pōkole, ʻo ia hoʻi, ua like kona radius o ka curvature me ke anawaena o waho o ka paipu, ʻo ia hoʻi, R=1D.

ʻO nā kuʻe lima radius lōʻihi ka mea maʻamau i hoʻohana ʻia. Hoʻohana wale ʻia nā kuʻekuʻe radius pōkole i ka wā e hālāwai ai i kekahi mau kūlana kūikawā, e like me ka lawa ʻole o ka wahi hoʻokomo.

Mai kahi hiʻohiʻona hana, ʻoi aku ka liʻiliʻi o ke kāʻei o nā kuʻe lima lōʻihi ma mua o nā kuʻe lima pōkole, ua hoʻemi nui ʻia ka ikaika o ka corrosion, a ʻoi aku ka liʻiliʻi o ke kū'ē, ʻoi aku ka maikaʻi ma mua o nā kuʻe lima pōkole. Ma kahi i kiʻekiʻe ai ke kaomi a i ʻole ke kiʻekiʻe o ka kahe kahe, e hoʻohana ʻia nā kuʻe lima radius lōʻihi. Inā koʻikoʻi nā koi kūpaʻa o ka pipeline conveying solid, e hoʻohana ʻia kahi kuʻekuʻe radius nui. Hoʻohana maʻamau ʻia nā radius pōkole i nā wai haʻahaʻa haʻahaʻa a i ʻole nā palena i ka hoʻokomo ʻana i nā kuʻekuʻe.

Nā kūlana hoʻokō like ʻole

Kuʻekuʻe kila kuhiliʻole lōʻihi: GB / T12459-2017; GB/T13401-2005; GB/T10752-1995; HGJ514-87; DL/T695-1999; D-GD87-0219.

Pōkole radius kuʻekuʻe lima kila: GB/T12459-2017; GB/T13401-2017; GB/T10752-1995; SH3408-1996; SH3409-1996.

Nā kiʻekiʻe waena like ʻole

ʻO ke kumu helu helu no ke kiʻekiʻe waena o ka kuʻekuʻe kila kuhiliʻole: anawaena * lehulehu No ka laʻana, ʻo ke anawaena nominal e pili ana o ka anawaena o waho 219mm he 200, a laila ʻo ke kiʻekiʻe waena o ka radius kuʻekuʻe kila kila he 200*1.524=304.8, lawe. 305;

ʻO ke kiʻekiʻe o ke kiʻekiʻe o ka kuʻekuʻe kila kuhili-pōkole pili i ka 200*1.015=203

Hiki ke ʻike ʻia nā ana kikoʻī kikoʻī o nā kuʻekuʻe kila kila ma ke kaomi ʻana ma aneʻi.
