Icyuma cya X70 gihwanye niki?
ISO 3183 - L485: Iki nicyuma cyumuyoboro ukurikije amahame mpuzamahanga kandi kirasa mumitungo ya API 5L X70.
CSA Z245.1 - GR 485: Iri ni ishyirahamwe ryubuziranenge bwa Kanada ryicyuma cya peteroli na gaze.
EN 10208-2 - L485MB: Iki nicyuma cyumuyoboro munsi yuburayi bugamije gukora imiyoboro yo gutwara peteroli na gaze.
Igipfukisho
Ntabwo duha abakiriya bacu imiyoboro yo mu rwego rwohejuru ya X70 gusa ahubwo tunatanga ubwoko bwinshi bwa serivisi zo gutwikira kugirango duhuze ibyifuzo byimishinga itandukanye.
Irangi: Irangi rya gakondo ritanga uburinzi bwibanze bwo kwangirika kandi birakwiriye kubidukikije bidakabije cyangwa kurinda by'agateganyo.
FBE: Bishyizwe hejuru yumuyoboro wicyuma ukoresheje uburyo bwo gutera amashanyarazi hanyuma bigakizwa nubushyuhe.Iyi coating ifite imiti irwanya imiti kandi ikwiranye nu miyoboro yo munsi cyangwa munsi y'amazi.
3LPE: Igizwe na epoxy coating, igipande gifatika, hamwe na polyethylene, itanga uburyo bwiza bwo kurwanya ruswa no gukingira imashini kuburyo butandukanye bwo gutwara imiyoboro yo munsi y'ubutaka.
3LPP: Bisa na 3LPE, igifuniko cya 3LPP kigizwe nibice bitatu, ariko ikoresha polypropilene nkigice cyo hanze.Iyi kote ifite ubushyuhe bwinshi kandi ikwiranye no kuvoma ahantu hafite ubushyuhe bwinshi.
Ipitingi irashobora gutoranywa hashingiwe kubidukikije byihariye bisabwa hamwe nibisabwa kugirango umuyoboro wizere kandi umutekano wumuyoboro wa API 5L X70 mugihe cya serivisi.
Impamvu zo kuduhitamo kuri X70 Umuyoboro
1. API 5L inganda zemewe: Inganda zacu zifite ibyemezo bya API 5L, byemeza ubuziranenge buhanitse kuva isoko kugeza ibicuruzwa byarangiye hamwe ninyungu yibiciro.
2. Ubwoko bwinshi bw'imiyoboro: Ntabwo dukora uruganda rukora ibyuma bisudira gusa ahubwo tunabika ububiko bwimiyoboro idafite ibyuma, kandi turashobora gutanga ubwoko butandukanye bwimiyoboro ishobora guhuza ibyifuzo byimishinga itandukanye.
3. Ibikoresho byuzuye: Usibye umuyoboro wibyuma, dushobora kandi gutanga flanges, inkokora, nibindi bikoresho bifasha, gutanga ibisubizo byamasoko imwe kumushinga wawe.
4. Serivise yihariye: Turashoboye gutanga ibisubizo byabigenewe dukurikije ibyo umukiriya akeneye, harimo gukora no gutunganya imiyoboro yicyuma ifite ibisobanuro byihariye.
5. Serivise zihariye: Kuva yashingwa mu 2014, isosiyete yitabiriye imishinga myinshi y’ubuhanga kandi ikusanya uburambe bukomeye mu nganda, bituma itanga serivisi zihariye n’inkunga.
6. Igisubizo cyihuse ninkunga: Itsinda ryabakiriya bacu rirashobora gutanga igisubizo cyihuse hamwe nubufasha bwa tekinike yumwuga kugirango ibibazo byawe nibikenewe bikemuke mugihe gikwiye.
