I-API 5L PSL2Ipayipi Lensimbi LSAW
Ipayipi yensimbi ye-LSAW ikhiqizwa ngensimbi ngaphakathi endlini ekhiqizwa futhi yancibilika esithandweni sikagesi, ephathwa ngama-slags okwenziwa futhi ephonswe ngama-casters aqhubekayo.Inqubo yokwenza insimbi esetshenzisiwe iqinisekisa ukuzuzwa kwensimbi ehlanzekile ngamakhemikhali ngokubhekiselwa kokuqukethwe kwesulfure ne-phosphor ehlinzeka ngezici eziphakeme zokudonsa, i-ductility kanye nokugqwala kwamapayipi okumele asetshenziswe emazingeni okushisa aphansi emithonjeni ehlukahlukene yokugqwala.
Ukugingqa usebenzisa isigayo sokubhoboza umshini kanye nogayo oluqhubekayo olufakwe i-mandrel engaguquki kuvumela ukubekezelelana kokulinganisa okuqinile okutholakala futhi kuqinisekisa ukuntuleka komzimba wepayipi kanye nokukhubazeka kwendawo.
Ukuze kuzuzwe insimbi ephezulu eqinile kanye ne-ductility kanye nesakhiwo sayo esidingekayo, ehlinzeka ukumelana nokugqwala okuphezulu emithonjeni ehlukahlukene yokugqwala, amapayipi aphathwa ukushisa esithandweni somlilo esihamba ngekhompyutha.Amaphesenti angama-70 amapayipi kawoyela angaphansi kokwelashwa ngokushisa.
Amapayipi ahlolelwa ukugeleza kwangaphakathi nangaphandle ngokuhlolwa okuzenzakalelayo okungaphazamisi kokuhlolwa kwe-ultrasonic ne-electromagnetic.Ipayipi iphetha ukuhlolwa ngemva kokuba i-beveling yenziwe ngokutholwa kwamaphutha kazibuthe-fluoroscopic.
Ngenkathi ukukhiqiza amapayipi kalayini angenamthungo kuqinisekisa ukuhlolwa kwezakhiwo ezimelana nokugqwala nge-hydrogen okuhlanganisa indlela yokuqhekeka ngaphansi kwe-NACE MR 02-84 kanye nendlela yokuqhekeka kwe-sulphide stress corrosion ngaphansi kwe-NACE MR 01-77.
I-Api 5l gr.bipayipi elingenamthungo
Injongo yepayipi elingenamthungo le-api 5l gr.b lilungele ukusetshenziswa ekudluliseni igesi, amanzi, namafutha kuzo zombili izimboni zikawoyela negesi yemvelo.

Ipayipi lensimbi le-API 5L X52
I-API 5l X52 iyindinganiso yepayipi likawoyela.
I-API SPEC 5L ivala ipayipi lolayini ongenamthungo kanye nepayipi lolayini elishiselwe.
Ukusetshenziswa: kumafutha, imboni yegesi yemvelo, umoya-mpilo, amanzi, ipayipi likawoyela;ingase futhi isetshenziswe ekwakhiweni kwengqalasizinda yobunjiniyela, ukulungiswa komgwaqo waseLinyuan, imigudu yokukhipha amanzi, isakhiwo sensimbi yensimbi, umbhoshongo wamandla kagesi aphezulu.
