Pipeline Technology- Ka nui a me ka mānoanoa o ka paipu kila

Huina nui paipu kila

ʻAʻole kūʻokoʻa ka nui o ka paipu a pono e mālama i kahi ʻōnaehana hoʻohālikelike kikoʻī.Aia nā ana o ka paipu kila ma nā millimeters, akā hoʻohana kekahi mau ʻāina i nā ʻīniha (inihi ma ka ʻōlelo Pelekania, a i ʻole zoll ma ka German).No laila, ʻelua ʻano paipu kila - TUBE a me PIPE.Hoʻohana ʻia ʻo TUBE i nā ʻoihana mechanical a i ʻole ka ikehu e wehewehe i ke anawaena o waho ma nā iniha.Hoʻohana ʻia ka PIPE ma ke ʻano he pipeline no nā media like ʻole.Hoʻohana ʻia ka nui PIPE e like me ka nui nominal o ka paipu kila.Hiki i ka paipu kila 12-inihi ke ʻike i ka helu helu o ke anawaena o loko.ʻO ka nui o ka PIPE i hoʻololi ʻia i mm ka laina makemake no ke anawaena o waho o ka paipu kila (ʻo ka laina mua e hoʻohana ana i ka EN10220, DIN2448, etc.).ʻAʻole ia e ʻōlelo ʻaʻole mākou e hoʻohana i ka laina ʻelua a me ke kolu.ʻO ka lua a me ke kolu o ka lālani he mau kūlana TUBE no ka hana ikehu a me nā paipu kila mechanical.

Paipu kila mānoanoa pā moʻo

ʻO ka pā mānoanoa o nā paipu kila mai ka British Units of Measurement, a ua hōʻike ʻia nā anaby nā hewa.ʻO ka mānoanoa o ka pā PIPE e ka moʻo Hōʻike (40, 60, 80, 120), a hoʻopili ʻia me nā pūʻulu kaumaha (STD, XS, XXS).ʻO kēia mau heluua hoʻololi ʻia nā waiwai i millimeters ma ke ʻano o ka moʻo mānoanoa o ka paia paipu.(E hoʻomaopopo: ʻAʻole mau ka waiwai o ka nui-Schedule40, akā pili i ke anawaena o waho o ka paipu. Hoʻohana ʻia nā unahi BWG a me SWG no ka waiwai mānoanoa o ka pā o ke ʻano TUBE. Ma hope o ka hoʻololi ʻana i millimeters, lilo kēia mau waiwai i ʻāpana o ka pā mānoanoa. ʻO ke anawaena o waho a me nā ana mānoanoa o ka paia o nā paipu kila pololei i hoʻohana ʻia ma ʻEulopa a me nā ʻāina e hoʻohana ana i ka International System of Units ua hoʻopuni ʻia i ka hoʻohālikelike.
