Ahịrị ọkpọkọ API nwere ígwè carbon
Pipeline tube bụ nke ụkpụrụ ANSI Petroleum.Ọrụ nke ọkpọkọ ahịrị bụ ịkwanye mmanụ, gas, mmiri si n'ubi gaa n'ụlọ nrụpụta.
Ọkpụkpọ ọkpọkọ gụnyere tube na-enweghị nkebi na tube welded.Mmepe nke teknụzụ efere ígwè pipeline na usoro ịgbado ọkụ na-agbasawanye ngwa ngwa nke ọkpọkọ welded.
Karịsịa na nnukwu dayameta ígwè tube, welded pipeline tube nwere uru na-enweghị atụ.
Nkọwa maka pipeline API:
1) Usoro usoro: ERW ígwè ọkpọkọ, LSAW stek ọkpọkọ, SSAW ígwè ọkpọkọ, oyi sere, Hot akpọrepu, DSAW
2) Ngwunye elu: Agba mkpuchi Varnish
3) Ụkpụrụ na ihe onwunwe: API 5L, API 5CT A, B, X42, X46, X52, X56, X60, X65, X70, X80 5L B, X42, X52 & API 5CT ASTM A106 GR B ASTM A53 GR B
4) Size: OD 33.4mm - 914mm maka enweghị nkebi ígwè ọkpọkọ, 323.8mm -1420mm maka LSAW ígwè ọkpọkọ, 219mm -3120mm
5) Ngwụsị ngwụcha: ngwụcha dị larịị ma ọ bụ ngwucha
7) Ngwa: mmanụ na-ebufe mmanụ na gas dị anya, pipeline njem mmiri
8) nkwakọ okwu: Standard seaworthy mbukota, General ụyọkọ mbukota
API 5L X60 ígwè ọkpọkọ
Nhazi ọkwa API 5L X60 PSL 1 sitere na nkọwapụta API Spec 5L maka Pipe Line.Ọkwa siri ike nwere nhọpụta X na-esote ike mkpụrụ kacha nta akọwapụtara nke igwe ọkpọkọ, tụrụ na kilopound kwa square inch (abiri ksi).Standard Line Pipe nwere ọkwa ọkwa A na B.
Ngwa: gas, mmiri na njem mmanụ na mmanụ na gas.
