Ipayipi eli-odwe ngaphansi kwalokhu kucaciswa kufanele lilungele ukugotshwa, ukuphephuka, kanye nokusebenza okufanayo kokubumba, kanye nokushisela.Lapho insimbi izoshiselwa, kucatshangelwa ukuthi inqubo yokushisela efanele izinga lensimbi kanye nokusetshenziswa okuhlosiwe noma isevisi izosetshenziswa.
I-API 5L GR.B Ukuqina Kodonga Olusindayo Ipayipi Lensimbi Lenziwe ngokudonswa okubandayo noma okugoqiwe okushisayo, njengoba kudingwa amakhasimende.

Esimeni sepayipi elihlolwe nge-hydro-statically ukuze libe nezingcindezi ezidlula izingcindezi ezijwayelekile zokuhlola, okunye ukubekezelela kungase kuvunyelwane ngakho phakathi komkhiqizi nomthengi.

Ukubekezelela okungaphandle kwendingilizi kusebenza kumadiayamitha aphezulu kanye nobuncane njengoba kukalwa ngegeji yebha, i-caliper, noma idivayisi ekala ubukhulu bangempela nobuncane bamadiayamitha.
Isilinganiso sobubanzi (njengoba silinganiswa ngetheyiphu yodayamitha) yesinye isiphetho sepayipi akufanele sihluke ngokungaphezu kuka-3/32 in. (2.38 mm) kusukela kolunye uhlangothi.

Amanothi:
1. Ukubekezelelwa kwesisindo kusebenza ezisindweni ezibaliwe zepayipi elinentambo nelihlanganisiwe kanye nezisindo ezifakwe kuthebula noma ezibaliwe zepayipi elingaphethe lutho.Lapho ukubekezelela ukuqina kodonga okunegethivu kuncane kunalokhu okubalulwe ngenhla kwethebula elichazwe umthengi, ukubekezelelwa kwesisindo okuhlanganisiwe kobude obubodwa kuzokwenyuswa kube ngamaphesenti angama-22.5 okungaphansi kokubekezelela okunegethivu.
2. Ngokulayishwa kwezimoto ezakhiwe ngamapayipi ezinto ezi-oda ezingaphezu kweyodwa, ukubekezelela ukulayishwa kwezimoto kufanele kusetshenziswe entweni ye-oda yomuntu ngamunye.
3. Ukubekezelelwa kwezinto ze-oda kusebenza enanini lilonke lamapayipi athunyelwe entweni ye-oda.
