1. Womic Steel: Ubushobozi bwo gukora n'imbaraga z'ikigo
Womic Steel Group ni uruganda rukomeye rukora ibintu bitandukanye kandi rutumiza mu mahanga ku isi rufite ubunararibonye bw'imyaka irenga 20 mu gukora ibikoresho bya karuboni, alloy, na stainless steel tubular. Urwego rwacu rugezweho rwo gukora imiyoboro ya SSAW rufite ubushobozi bwo gukora imiyoboro irenga toni 15.000 buri kwezi, rukora imiyoboro yubatswe mu buryo bwa spiral, ikoreshwa mu bwubatsi, ibikorwa remezo, n'inganda ku isi yose.
Ingano y'umusaruro w'umuyoboro wa SSAW:Ubugari bwo hanze kuva kuri 219mm kugeza kuri 3.000mm (santimetero 8 kugeza kuri 120) bwo gukora SSAW. Ubunini bw'urukuta kuva kuri 5.0mm kugeza kuri 25.4mm. Uburebure bumwe kuva kuri 6m kugeza kuri 18m, hamwe n'uburebure bwihariye kugeza kuri 60m buboneka ku mishinga y'urufatiro rwimbitse n'inyubako.
Ibyemezo by'Ubuziranenge n'Iyubahirizwa ry'Amategeko:
ISO 9001:2015 Yemejwe:Sisitemu yo gucunga ubuziranenge mu gukora imiyoboro y’amashanyarazi no kugenzura ubuziranenge, igamije kwemeza ko ubuziranenge bw’ibicuruzwa buhoraho kandi bugakomeza kunozwa mu bikorwa byose by’inganda.
Uruhushya rwa API 5L Monogram:Womic Steel ifite uruhushya rwa API 5L rwo gukora imiyoboro ya Line Pipe, bigaragaza ko twiyemeje gukurikiza amahame meza yo gukora.
Ikimenyetso cya CE (PED 2014/68/EU):Imiyoboro yacu y’inyubako ikurikiza amabwiriza y’ibikoresho by’umuvuduko by’i Burayi (PED) 2014/68/EU. Ikimenyetso cya CE kiraboneka iyo ubisabye.
Icyemezo cya EN 10204 3.2:Uretse ibyemezo bisanzwe bya 2.2 na 3.1 Mill Test Certificates, dutanga ibicuruzwa bifite icyemezo cy’igenzura 3.2, byemejwe n’inzego za gatatu zemewe n’Umuryango w’Ubumwe bw’u Burayi.
Ibyemezo by’Ubugenzuzi bw’Uruhande rwa Gatatu (TPI):Ibicuruzwa byacu n'uburyo dukora byemezwa kandi bigagenzurwa n'ibigo bikomeye mpuzamahanga birimo SGS, BV, TÜV, na DNV.
Izindi mpamyabumenyi zihari:ISO 14001: 2015, ISO 45001: 2018
Kumenyekana ku Isi:Womic Steel ni umucuruzi wizewe ku ba rwiyemezamirimo ba EPC ku isi, amasosiyete y'ubwubatsi, n'abakora ibikorwa remezo, ikorera ibihugu birenga 80 ku isi.
2. ASTM A500 GR.B: Imiterere y'ibikoresho n'imikorere yabyo
ASTM A500 GR.Bni ibipimo ngenderwaho by’Abanyamerika ku miyoboro y’ibyuma bya karuboni ikozwe mu buryo bukonje kandi idafite umugozi mu buryo bw’uruziga. Inyito ya "GR.B" yerekana Icyiciro cya B, gitanga imbaraga nkeya za 315 MPa (46.000 psi) n’imbaraga nkeya zo gukurura za 400 MPa (58.000 psi). Icyiciro cya B ni cyo gipimo gikoreshwa cyane mu miterere y’inyubako, gitanga uburinganire bwiza bw’imbaraga, ubusudi, no gushingwa.
ASTM A500 GR.B yakozwe by'umwihariko kugira ngo ikoreshwe mu nyubako, itanga ubushobozi bwo gusudira neza kugira ngo ihuzwe n'umurima, ubushobozi bwo gupfunyika no gushingwa neza, kandi ifite imbaraga zihagije ku nyubako zitwara imizigo. Ugereranyije n'uburyo bwa ASTM A252 bwo gufunga, A500 GR.B ifite ubushobozi bwo kwihanganira ibintu mu buryo burambuye kandi yagenewe gukoreshwa mu nyubako aho kuyikoresha mu kuyiyobora.

Ibibazo Bikunze Kubazwa (Ibibazo Bikunze Kubazwa) - Umuyoboro w'Ibyumba bya ASTM A500 GR.B SSAW
Q: Ni irihe tandukaniro riri hagati ya ASTM A500 GR.B na ASTM A252 GR.3?
A: ASTM A500 GR.B ifite imbaraga nkeya za 315 MPa, mu gihe ASTM A252 GR.3 ifite 345 MPa. A500 GR.B ifite ubushobozi bwo kwihanganira ibintu mu buryo burambuye kandi yagenewe imiterere y’inyubako. A252 GR.3 yagenewe by’umwihariko gushyiramo no gukoresha mu gutunganya. A500 GR.B itanga uburebure bwinshi (23% ugereranyije na 20%), bigaragaza ubushobozi bwo gukora neza.
Q: Ese ASTM A500 GR.B ishobora gukoreshwa mu gukusanya?
A: Yego, ASTM A500 GR.B irashobora gukoreshwa mu gushyiramo imigozi, cyane cyane ku byerekeye ishingiro ryoroheje. Ariko, ku byerekeye ishingiro rikomeye ryo mu mazi n'iry'uburebure, ASTM A252 GR.3 cyangwa EN 10248 S355GP ni byiza kubera imbaraga zazo nyinshi n'ibisabwa byihariye mu gutwara.
Q: Ni ubuhe burebure ntarengwa bw'umuyoboro umwe wa ASTM A500 GR.B SSAW?
A: Uburebure busanzwe ni metero 6, metero 12, na metero 18. Uburebure bwihariye bugera kuri metero 60 buraboneka bitewe n'umurambararo n'ubugari bw'urukuta.
Q: Ni izihe nzira zo kurangiza ubuso zihari?
A: Dutanga ibikoresho byo mu bwoko bwa "barn (mill scale), amavuta, ikara, ishyushye, hamwe n'ibindi bikoresho bitandukanye birwanya ingese.
Q: Ese ushobora gutanga imiyoboro y'inyubako hamwe n'igenzura ry'umuntu wa gatatu?
A: Yego. Dufasha mu igenzura ryakozwe na SGS, BV, TÜV, DNV, cyangwa uhagarariye umukiriya uwo ari we wese.
Q: Ni izihe nyandiko zitangwa kuri buri kohereza?
A: Icyemezo cy'ikizamini cy'inganda (EN 10204 Ubwoko bwa 3.1), Raporo y'igenzura ry'ibipimo, Raporo za UT, Raporo za RT (niba byavuzwe), Inyandiko z'ikurikirana ry'ibicuruzwa, Urutonde rw'ibipakiye, Inyemezabwishyu y'ubucuruzi, n'icyemezo cy'aho bikomoka.
