Mayeso a Impact
Kuyesa kwamphamvu kudzachitika molingana ndi EN 10045-1.
Mtengo wapakati wa magulu atatu a zitsanzo udzakhala wofanana kapena wokulirapo kuposa mtengo womwe watchulidwa.
Mtengo wapayekha ukhoza kukhala wotsika kuposa mtengo womwe watchulidwa, koma siwochepera 70% ya mtengowo.
Kuyesa kosawononga
Pochita NDT pa ma welds m'magawo opanda kanthu, zofunikira zotsatirazi ziyenera kukwaniritsidwa.
Magetsi Welded Magawo
Kukwaniritsa chimodzi mwazofunikira izi:
a) TS EN 10246-3 mpaka mulingo wovomerezeka E4, kupatula kuti njira yozungulira ya chubu/pakeke sidzaloledwa;
b) EN 10246-5 ku mulingo wovomerezeka F5;
c) EN 10246-8 mpaka mulingo wovomerezeka U5.
Magawo Olowetsedwa Arc Welded

Maonekedwe ndi Kukonza Zowonongeka
Maonekedwe Pamwamba
Magawo opanda kanthu azikhala ndi malo osalala ogwirizana ndi njira yopangira yomwe imagwiritsidwa ntchito;tokhala, grooves kapena osaya longitudinal grooves chifukwa cha kupanga ndondomeko amaloledwa ngati yotsalira makulidwe mkati kulolerana.
Malekezero a gawo la dzenje ayenera kudulidwa mwadzina lalikulu kuti agwirizane ndi axis mankhwala.
Kukonza Zowonongeka
Zowonongeka zapamtunda zitha kuchotsedwa pogaya malinga ngati makulidwe ake ndi osachepera kutsika kovomerezeka komwe kumatchulidwa mu BS EN 10219-2 pambuyo pokonzanso.
Pazigawo za dzenje la tirigu, kukonza thupi ndi kuwotcherera sikuloledwa pokhapokha ngati atagwirizana.
Njira zokonzera weld ziyenera kutsata zofunikira za EN ISO 15607, EN ISO 15609-1, ndi EN ISO 15614-1.
Dimensional Tolerances
Kulolera kwapang'onopang'ono kudzakhala molingana ndi zofunikira za EN 10219-2 ndipo chidwi chidzaperekedwa ku mawonekedwe a gawo la mtanda.

Zokhala ndi malata
TS EN 10219 Machubu a Hollow amatha kukhala ndi malata otentha kwa moyo wautali wautumiki.
Machubu obowo amawathiridwa mu bafa lomwe lili ndi zinc zosachepera 98% kuti apange malata.
Chizindikiro cha BS EN 10219
Zomwe zili muzitsulo zachitsulo ziyenera kukhala:
Dzina lachitsulo, mwachitsanzo EN 10219-S275J0H.
Dzina kapena chizindikiro cha wopanga.
Chizindikiritso, mwachitsanzo nambala ya oda.
TS EN 10219 machubu achitsulo amatha kuzindikirika ndi njira zingapo zowonetsetsa kuti zizindikirika mosavuta komanso kutsata, kaya ndi penti, masitampu, zomatira, kapena zolemba zina zowonjezera, zomwe zitha kugwiritsidwa ntchito payekhapayekha kapena kuphatikiza.
Mapulogalamu
Kugwiritsiridwa ntchito kwa muyezo wa BS EN 0219 kumakhudza mbali zonse zofunika pakupanga zitsulo.
Zomanga:TS EN 10219 mapaipi achitsulo amagwiritsidwa ntchito kwambiri pantchito yomanga, monga kumanga milatho, chithandizo chanyumba, ndi zina zambiri.
Kumanga zomangamanga: amagwiritsidwa ntchito m'mapulojekiti osungira madzi, kumanga misewu, mapaipi, ndi ntchito zina zomanga zomangamanga, monga mipope ya ngalande, mapaipi amadzi, ndi zina zotero.
Kupanga: Mapaipi achitsulowa amagwiritsidwanso ntchito popanga zida zamakina, makina otumizira, ndi ntchito zina zamafakitale.
Municipal engineering: Mu engineering yama tauni yamatauni, mapaipi achitsulo a BS EN 10219 atha kugwiritsidwa ntchito kupanga zotchingira, njanji, zotchinga misewu, ndi zina zotero.
Zokongoletsera zomangamanga: Mapangidwe okongoletsera ndi mphamvu zamachubu achitsulo amawapanga kukhala zinthu zomwe zimagwiritsidwa ntchito pokongoletsa zomangamanga, monga masitepe, ma balustrade, mabatani okongoletsera, ndi zina zotero.
Chiyambireni kukhazikitsidwa mu 2014, Botop Steel yakhala chitoliro chotsogola cha carbon steel ku Northern China, chomwe chimadziwika ndi ntchito zake zabwino kwambiri, zinthu zamtengo wapatali, komanso mayankho athunthu.Zogulitsa zamakampani zimaphatikizansopoopanda msoko, mapaipi achitsulo a ERW, LSAW, ndi SSAW, komanso zopangira mapaipi, ma flanges, ndi zitsulo zapadera.
Ndi kudzipereka kwakukulu ku khalidwe, Botop Steel imagwiritsa ntchito maulamuliro okhwima ndi mayesero kuti atsimikizire kudalirika kwa zinthu zake.Gulu lake lodziwa zambiri limapereka mayankho aumwini ndi chithandizo cha akatswiri, ndikuyang'ana kukhutira kwamakasitomala.
