Imiyoboro ya Api 5l y'umurongo iva kuri grade B kugeza kuri X70 Od kuva kuri 219mm kugeza kuri 3500mm

Ibisobanuro bigufi:

Ibi bisobanuro bigamije gutanga amahame ngenderwaho mu nganda zikoresha imiyoboro y'amazi, gazi na peteroli mu nganda zikora peteroli na gaze karemano.

Hari urwego rubiri rw'ibicuruzwa, PSL 1 na PSL 2, PSL 2 ifite ibisabwa bisabwa kugira ngo habeho ingano ya karuboni, gukomera kw'ibanga, imbaraga ntarengwa z'umusaruro n'imbaraga zo gukurura.

Icyiciro cya B, X42, X46, X52, X56, X60, X65, X70 na X80.

Cangzhou Spiral Steel pipes group co.,ltd itanga imiyoboro ya SAWH ifite urwego kuva kuri API B kugeza kuri X70, twabonye icyemezo cya API 5L imyaka myinshi mbere yaho none ubu imiyoboro yacu ikoreshwa cyane na CNPC, CPECC mu mishinga yabo y'imiyoboro.

Ohereza imeri kuri twe

Ibisobanuro birambuye ku gicuruzwa

Umuyoboro ugomba kwihanganira igeragezwa rya hydrostatic nta gusohoka unyuze mu mugozi wo gusudira cyangwa ku mubiri w'umuyoboro
Ibikoresho byo guhuza ntibigomba gupimwa hifashishijwe ikoranabuhanga rya hydrostatic, mu gihe ibice by'imiyoboro byakoreshejwe mu gushyira ikimenyetso ku bikoresho byo guhuza byapimwe neza hifashishijwe ikoranabuhanga rya hydrostatic mbere y'uko bishyirwa ku murongo.

Uburyo bwo gukurikirana:
Ku muyoboro wa PSL 1, uwakoze umushinga agomba gushyiraho no gukurikiza amabwiriza yanditse yo kubungabunga:
Ishusho y'ubushyuhe kugeza igihe buri kizamini cy'ubushyuhe kijyanye nabyo kizakorwa kandi hakubahirizwa ibisabwa byagenwe.
Icyitonderwa cy'igice cy'ibizamini kugeza igihe buri kizamini cy'imashini gifitanye isano gikozwe kandi hakubahirizwa ibisabwa byavuzwe.
Ku muyoboro wa PSL 2, uwakoze uyu muyoboro agomba gushyiraho no gukurikiza amabwiriza yanditse yo kubungabunga ubushyuhe n'imiterere y'igice cy'igerageza kuri uwo muyoboro. Ayo mabwiriza agomba gutanga uburyo bwo gukurikirana uburebure bwose bw'umuyoboro kugeza ku gice cy'igerageza gikwiye n'ibisubizo by'ibizamini bya chimique bifitanye isano.

Ibanjirije iyi: Imyambaro ya Epoxy ifatanye na Fusion-Bonded Awwa C213 Standard

Ibikurikira: Imiyoboro y'icyuma ishongeshejwe mu buryo bw'umwuka ASTM A252 Icyiciro cya 1 2 3
