L360 paipa u'amea masani fa'agaioiga paipa felauaiga paipa
L360 Pipeline Steel, Faamoemoega: API SPEC 5L-2011 (Pipeline Specification), atiae ma lomia e le American Petroleum Institute, o loʻo faʻaaogaina i le lalolagi atoa.Paipa paipa: E felauai le suauu, kesi po'o le vai mai le eleele e ala i paipa i le suau'u ma kesi alamanuia.Pipeline paipa e aofia ai seamless ma uelo paipa lua ituaiga, o le pito paipa e mafolafola pito, filo filo ma socket pito;O le faiga o feso'ota'iga o le fa'au'uga fa'auiloga, feso'ota'iga pa'u, feso'ota'iga socket ma isi.O mea autu o le paipa o le B, X42, X46, X56, X65, X70 ma isi vasega sila.Na pasia e le matou kamupani le tusipasi API (API 5CT ma API 5L) ia Aokuso 2009.
L360 Pipeline Steel, API SPEC 5L GB/T9711.1 GB/T9711.2 Saina National Standard Application: Oxygen, vai ma paipa tu'uina atu suauu i le suauu ma kasa masani alamanuia B, X42, X52, X60, X65, X70 L245 L290 L320 L360 L390 L450 L485
Faatasi ai ma le atinae o le pipeline tekinolosi ipu uamea ma le alualu i luma o le faia o paipa uelo, tekinolosi uelo, o le tele o talosaga o le paipa ma le paipa uelo i faasolosolo faalautele, aemaise lava i le lautele lautele uelo paipa vasega tulaga lelei sili atu ona manino, ma tau tau, paipa uelo ua pule i le fanua o laina paipa, lea faatapulaaina le atinae o le uamea stainless seamless laina paipa laina.I le 2004, o le gaosiga o le paipa fa'alelei e tusa ma le 400,000 t, u'amea vasega e aofia ai le X42-70, ma o le ituaiga o paipa i luga o le sami ma lalo o le paipa.
O le gaosiga o paipa paipa maualuga uamea e faʻaaogaina ai le faʻavevelaina o togafitiga faʻavevela, o le tau o le gaosiga o paipa faʻafefeteina e sili atu le maualuga nai lo paipa uelo, ma faʻatasi ai ma le faʻaleleia atili o le uʻamea, e pei ole X80 ma luga aʻe o le faʻatapulaʻaina o paipa paipa i luga ole kaponi tutusa. , o le faiga masani o paipa seamless e faigata ona ausia manaoga o tagata e faaaogāina;O lo'o fa'atinoina galuega su'esu'e fa'asaienisi ta'itasi ta'itasi 12Cr1moV paipa fa'ameamea ina ia fa'aleleia atili ai le fa'a'ele'ele o ana paipa paipa ma le fa'atinoga mautu i le si'osi'omaga maualalo ma maualuga le vevela.
