Payipu y’omusono omugolokofu ye payipu y’ekyuma eweweddwa ng’omusono guddukira mu kkubo lye limu n’obuwanvu bwa payipu. Ekyuma ekipande oba ekipande kikolebwa mu ngeri eyeetooloovu, olwo empenda zombi ne ziweta wamu. Payipu eno ekozesebwa ku layini z’amazzi aga puleesa entono, empagi z’ebizimbe, omulimu gwa payipu z’okuzimba, ne pulojekiti z’amafuta oba ggaasi ng’omutindo ogulondeddwa n’omutindo gw’okugezesa bikwatagana n’omulimu.
Ekkubo ly’okufulumya payipu y’omusono omugolokofu nnyangu okutegeka ku sayizi nnyingi eza bulijjo. Okuweta kwa frequency enkulu-kutera okukozesebwa ku payipu entono n’eza wakati, ate okuweta mu mazzi mu mazzi (submerged arc welding) kukozesebwa ku payipu za dayamita ennene. Layini ya weld esobola okwekebejjebwa, okusalibwa, n’okugezesebwa nga tennaweebwa. Ekintu kino era osobola okukisiiga, okukisengejja, okugaziwa oba okusalibwa okutuuka ku buwanvu obutakyukakyuka. Ku kukozesa ekifo, omuguzi alina okukebera dayamita, obuwanvu bwa bbugwe, omutindo gw’ekyuma, kungulu wa weld, n’okuteekateeka enkomerero. Ebintu ebyo bwe biba bitegeerekeka bulungi, ekintu kino kikwatagana ne pulojekiti nnyingi ez’amazzi, ez’okuzimba, ne payipu z’ekyuma mu bulambalamba.

Enkola y’okukola ebintu
1. Ku payipu y’omusono omugolokofu, ekyuma oba pulati kikolebwa mu ngeri ya payipu.
2. Empenda y’ekiyungo ewewebwa n’okuweta kwa frequency enkulu-frequency current oba submerged arc welding.
3. Payipu eweebwa sayizi, esalibwa, ekeberebwa, era n’elongoosebwa ku ngulu nga yeetaagibwa.
Kozesa Emisango
1. Layini za payipu z’amazzi n’empewo eza puleesa entono.
2. Okuzimba empagi, fuleemu, n’ebizimbe eby’ekyuma byonna.
3. Ebitundu bya payipu z’amafuta ne ggaasi ow’obutonde wansi w’omutindo ogukwatagana.
Ebiwandiiko by’okupakinga n’okutuusa ebintu
1. Obubonero bwa bundle bulina okulaga obunene, ekigezo, obuwanvu, n’obungi.
2. End protectors oba bevel protection zisobola okugattibwako okumala long-distance delivery.
3. Okusiiga kungulu kulina okukeberebwa nga tonnatikka oba payipu ejja kuterekebwa ebweru.
