"Lamulirani muyezo ndi tsatanetsatane, onetsani mphamvu ndi khalidwe". Bizinesi yathu yayesetsa kukhazikitsa ogwira nawo ntchito aluso komanso okhazikika ndikuwunika njira yabwino yowongolera mapaipi a Straight Carbon Steel Welded Pipes. Ubwino wabwino ndikukhalapo kwa fakitale, kuyang'ana pa zomwe makasitomala amafuna ndiye gwero la kupulumuka ndi kupita patsogolo kwa kampani, Timatsatira kukhulupirika ndi chikhulupiriro champhamvu chogwirira ntchito, kusaka chitsogolo kubwera kwanu!

Pakuti welded mpweya zitsulo chitoliro, pali 2 waukulu luso ayenera kuzindikira kuti ERW (magetsi kukana kuwotcherera) ndi SAW (submerge arc weld). Mapaipi omwe amagwiritsa ntchito ukadaulo wotere amagwiritsidwa ntchito makamaka pamakampani amafuta ndi gasi, koma onse ali ndi mwayi wawo, chifukwa chake kugwiritsa ntchito kumakhala kosiyana.

ERW chitoliro chimapangidwa kuchokera ku mbale yachitsulo, pali msoko umodzi wowotcherera, ndipo chifukwa chingwe chowotcherera cha ERW chitoliro chimachokera ku chitoliro cha mayi, sichifunika solder flux, kotero makina amakina ndi abwino kwambiri. Ndipo chifukwa cha makhalidwe ake apamwamba kupanga dzuwa, mtengo wotsika, kupulumutsa zinthu, ndi zodzichitira zosavuta, poyerekeza ndi SAW chitoliro, ERW chitoliro ndi chitoliro zitsulo ndi ntchito zapamwamba mankhwala, kutsogolera khalidwe ndi ntchito ndi ndalama m'munda wa mafuta ndi gasi yosungirako. ndi mayendedwe. Makamaka kutsatira kukula kwa umisiri, khalidwe ngati welded mzere ndi bwino kwambiri, kudzera ntchito zamakono zamakono, cholinga ndi kuthetsa nkhawa, kufewetsa ndi kuyeretsa dongosolo, ndi kusintha mabuku katundu makina a kuwotcherera kutentha anakhudzidwa zone. Chitoliro chamtundu wa ERW sichingasiyanitsidwe kokha ndi weld, komanso coefficient yowotcherera imafika 1, yomwe imazindikira kufananiza kwa mawonekedwe a weld ndi zinthu zoyambira.

Kachulukidwe kaukadaulo wa SAW ndi wokwera kwambiri, ndipo kusanja kwa flux kumalepheretsa kutentha kwachangu ndikuyika m'dera la soldering. Kuwotcherera kwa arc pansi pamadzi kumakhala ndi msoko wapamwamba kwambiri, kupanga bwino kwambiri, kulibe kuwala kwa arc komanso utsi wochepa. Mipope yachitsulo yonyezimira ya arc imagwiritsidwa ntchito kwambiri muzotengera zokakamiza, zopangira zitoliro, mizati, mizati, zamadzimadzi otsika, komanso ntchito zamapangidwe azitsulo. Koma m'mayiko otukuka mafakitale mafuta, chitoliro cha SAW sichiloledwa chifukwa malire ake, kokha mu China SAW chitoliro akadali kuloledwa makampani mafuta ndi malire.

Ubwino wabwino komanso mtengo wololera "ndizo mfundo zathu zamabizinesi. Ngati muli ndi chidwi ndi malonda athu ndi mayankho kapena muli ndi mafunso, onetsetsani kuti mwamasuka kutilankhula nafe. Tikuyembekeza kukhazikitsa maubale ogwirizana nanu posachedwa.

Kugwiritsa ntchito

Amagwiritsidwa ntchito makamaka pazigawo zamphamvu ndi zokakamiza, komanso pazolinga zonse za nthunzi, madzi, gasi ndi mapaipi amlengalenga.

Chigawo cha Chemical

A Chiwerengero cha zinthu zisanu izi sichiyenera kupitirira 1.00%.

B Pakuchepa kulikonse kwa 0.01% muzambiri za kaboni, kuchuluka kwa manganese kumaloledwa kuwonjezeka ndi 0.06%, koma kuchuluka kwake sikungapitirire 1.35%.

C Kuchepa kulikonse kwa 0.01% muzambiri za kaboni kumapangitsa kuti manganese achuluke ndi 0.06%, koma kuchuluka kwake kuyenera kusapitilira 1.65%.

Mechanical Property

A Kutalikitsa kocheperako kwa kutalika kwa gauge 2in. (50mm) zidzatsimikiziridwa ndi chilinganizo zotsatirazi:

e=625000(1940)A^0.2/U^0.9

e = kutalika kochepa kwa geji 2in. (50mm), peresenti yozungulira mpaka 0.5% yapafupi;

A = Kuwerengedwa molingana ndi kukula kwakunja kwa chubu chodziwika bwino kapena m'lifupi mwadzina lachitsanzo chokhazikika komanso makulidwe ake a khoma, ndikuzunguliridwa kudera lapafupi kwambiri lachitsanzo chokhazikika cha 0.01 in.2 (1 mm2), ndipo Imafananizidwa ndi 0.75in.2 (500mm2), iliyonse yomwe ili yaying'ono.

U = mphamvu yocheperako yokhazikika, psi (MPa).

B Pamitundu yosiyanasiyana yamitundu yosiyanasiyana yamayeso oyeserera komanso mphamvu zocheperako zokhazikika, kutalika kocheperako kumawonetsedwa mu Table X4.1 kapena Table X4.2, malingana ndi kagwiritsidwe ntchito kake.

Chofunikira Choyesa

Kuyesa kwamphamvu, kuyesa kupindika, kuyesa kwa hydrostatic, kuyesa kwamagetsi osawononga ma welds.
