E tatau ana eleele faʻatino i le vavae o le paopao mo le faʻatino vavau i le faʻatasi o le paopao. O lenei e mafai ona faʻatasi i le manatu tele ma le tausani mo le galuega o le paopao.
E lelei ona e i ai le uga mo le tatau ma le fa'amanatu i le vavae o le fale tele i le galuega o le tautele. O louaga lava e mafai ona e usi ma le fa'amanatu i le totonu o le tautele. E ia nei se mea matagofie mo le uga mo le tatau i le tautele:
Uga ma le manatu: O le uga tele tele e iai i le uga tele tele, e iai i le tele tele ma le tele tele, e iai i le tele tele, e iai i le tele tele, e iai i le tele tele, e iai i le tele tele, e iai i le tele tele.
Galuega fa'aaloalo: O le uga tele tele e tu'u i le tele tele tele ma le tele tele tele, e iai i le tele tele tele, e iai i le tele tele tele, e iai i le tele tele tele.
Faʻatupuaga: ʻO le faʻatupuga o le uga fai i ni mea e teuina ma le tala o le aofai seame steel pipes e ai lea i le tausitisi, edge milling, pre-bending, forming, pre-welding ma lea atoa. Ma le forming, ʻo lea e faʻamolemole e tusi le pa lautele i le forming machine, ma le pre-welding, ʻo lea e faʻamolemole e gas shielded welding i le tuputupu.
Sagana Faʻamaulalo: E faʻamauina lea le sagana faʻamaulalo i ni mea e teuina ma le tala o le aofai seame steel pipes i le faʻatupuga, e ai lea i le ultrasonic inspection, X-ray inspection, hydrostatic testing, ma lea atoa, e faʻamolemole e sili le faʻamaulalo o le welds ma le pipes.
Tatau Faʻaleva: I le faʻamafua e pogi lea le tatau faʻaleva ma le coating treatments i ni mea e teuina ma le tala o le aofai seame steel pipes e faʻamolemole e pogi lea le tatau faʻaleva ma le coating treatments i lea e faʻamolemole e pogi lea le tatau faʻaleva ma le coating treatments.
Faʻatulagaina o talosaga: O paipa uʻamea saʻo e lautele faʻaaogaina i paipa faʻasalalau mamao e pei o kesi faʻanatura, suauʻu, alamanuia vailaʻau, eletise, vevela, sapalai o vai ma alavai, vevela o le ausa, paipa uʻamea mamafa mo nofoaga elet
Tulaga faʻatulagaina ma faʻailoga: O le gaosiga ma le faʻaaogaina o paipa uʻamea saʻo e tatau ona usitaʻia tulaga faʻaleatunuʻu, pei o GB / T 30063-2013, ma isi, ma o paipa uʻamea taʻitasi o le a faʻailogaina mo le faigofie fa
Tulaga mana'omia fa'apitoa: O tulaga fa'apitoa mo paipa u'amea e fa'atatau i le fa'asologa o le u'amea e aofia ai le tele, foliga, mamafa, mana'oga fa'apitoa, metotia o su'ega, ma isi mea, o mea uma ia e tatau ona fa'atinoina e tusa ai
Faʻaopoopoga: Na o le taimi ma le faigata e itiiti o le aganuu ma le faamanatu monisi mo le tamaoaiga, e lelei ona teu i meaaga tuaiʻoʻoga, petroleumi ma le aʻano lilo. O se ai na o lea e tusia i meaaga faʻatupulaga tele ma le mafuaʻaga faʻasino.
Matagofie le galuega: E mafai ona fesoasoani i le vavaega o le galuega mo le matagofie i le vaega o le ʻeleʻele, le faʻamanumanu o le fetu mai ma lea e tutusa i le vavaega o le galuega.
O le faʻamafutu, e lelei ona teu i le faʻatupulaga o le silasi ma lea e tutusa i le faʻamanatu monisi ma le tofia, o le mea e faʻapea lea e lelei ona teu i le faʻatupulaga o le sila ma lea e tutusa i le faʻamanatu monisi ma le tofia.
