Amathegi Omkhiqizo

Ipayipi lensimbi elingenamthungo elinokushisa okuphansiingasebenza endaweni ebanda kakhulu engu- -45~-195℃. Inzuzo evelele yepayipi lensimbi elingenamthungo lokushisa eliphansi ukuthi ingasebenza endaweni ephansi kakhulu, okungenakuqhathaniswa nayoipayipi lensimbi elingenamthungo elijwayelekile. Ipayipi lensimbi elingenamthungo elinokushisa okuphansi linamandla amahle kanye nokuqina okuphansi, futhi lisetshenziswa kabanzi ekukhiqizweni kwemishini esezingeni eliphansi lokushisa kuphethiloli, amakhemikhali, umanyolo kanye neminye imboni enezinga lokushisa elisebenzayo elingu - 45~- 195 ℃. Ngokuthuthuka kwezimboni ezifanele, izidingo zezinto azigcini nje ngokukhawulelwa ezidingweni eziyisisekelo njengezakhiwo zemishini kanye nezakhiwo zokushisela, kodwa futhi nezidingo zokumelana nokugqwala kwe-H2S kwamapayipi ezinga lokushisa eliphansi.

Ipayipi lensimbi elingenamthungo lokushisa eliphansi

Ipayipi lensimbi elingenamthungo elinokushisa okuphansi liyasebenza kubunjiniyela bamapayipi endaweni ephansi yokushisa. Kunezinqubo ezimbili: ukudweba okubandayo kanye nokugoqa okushisayo. Ngokombono womklamo wensimbi, ukwenza insimbi, ukugoqa, ukwelashwa kokushisa kanye nezinye izinqubo zepayipi lensimbi elingenamthungo elinokushisa okuphansi kufanele kulawulwe ngokuqinile ukuqinisekisa ukuthi ipayipi lensimbi elingenamthungo elinokushisa okuphansi linamandla amahle, ukuqina kanye nokumelana nokugqwala. Ngezidingo zobuchwepheshe zepayipi lensimbi elingenamthungo elinokushisa okuphansi, inhlangano yokukhiqiza kanye nezindleko zokukhiqiza zepayipi lensimbi kufanele kucatshangelwe ngokuphelele. Ukwakheka kwepayipi lensimbi elingenamthungo elinokushisa okuphansi kudinga ukuqinisekisa ukuthi umkhiqizo unamandla afanele, ukuqina okuphezulu kokushisa okuphansi, kanye nenqubo yokwelapha ukushisa elula Ukushibilika okuhle kanye nokumelana nokuqhekeka okubangelwa yi-hydrogen.

Izinga eliphezulu lepayipi lensimbi elingenamthungo elisezingeni eliphansi lokushisa i-ASTM A333 - Ipayipi Lensimbi Elingenamthungo Nelihlanganisiwe Lensizakalo Yokushisa Okuphansi

3.U: Uma imikhiqizo etholiwe itholakale ingahambisani nemikhiqizo efunwa yinkontileka, uzokwenzenjani?
A: Uma imikhiqizo etholiwe itholakale ingahambisani nemikhiqizo, uhlu lwezinkontileka, lapho sithola izithombe kanye nemibhalo esemthethweni kanye nedatha evela eceleni kwakho, uma kuqinisekiswa ukuthi ayihambisani, sizoyikhokhela leyo ndleko okokuqala.
4.Q: Isikhathi sakho sokulethwa singakanani?
A: Ngokuvamile kuba yizinsuku ezi-5-10 uma izimpahla zisesitokweni. noma kuba yizinsuku eziyi-15-20 uma izimpahla zingekho esitokweni, kuba ngokwenani.
5.U: Ingabe uyanikeza amasampula?
Ingabe kumahhala noma kungaphezulu? A: Yebo, singanikeza isampula futhi singakhokhi izindleko zokuthutha.
6.U: Ithini imigomo yakho yokukhokha?
A: Inkokhelo<=1000USD, 100% kusengaphambili. Inkokhelo>=1000USD, 30% T/T kusengaphambili, ibhalansi ngaphambi kokuthunyelwa.

UKUGQIBELA KWENQUBO YEPHAYIPHI YENSIMBI ENGENAMTHUNGO

Ukugeleza kwenqubo-kwepayipi-lensimbi elingenamthungo

UKUPHAKISHA NOKUTHUMELA

ISETHULO SETHIMU YAMAKHASIMENDE

Okwedlule: ifektri yeshubhu yesikwele engenamthungo

Olandelayo: ishubhu eyindilinga engunxande engenamthungo yomkhiqizo we-YuantaiDerun

Le nkampani ibheka kakhulu ikhwalithi yemikhiqizo, itshala imali eningi ekwethulweni kwemishini ethuthukisiwe kanye nochwepheshe, futhi yenza konke okusemandleni ayo ukuhlangabezana nezidingo zamakhasimende ekhaya nakwamanye amazwe.
Okuqukethwe kungahlukaniswa cishe kube: ukwakheka kwamakhemikhali, amandla okukhiqiza, amandla okudonsa, impahla yomthelela, njll.
Ngesikhathi esifanayo, inkampani ingenza futhi izinqubo zokuthola amaphutha kanye nokufaka i-annealing ku-inthanethi kanye nezinye izindlela zokwelapha ukushisa ngokwezidingo zamakhasimende.
