I-ASTM A234 yinkqubo esemgangathweni yemibhobho ye-pube ye-carbon secbon steel kunye nentsimbi ye-ofisi yendlela yobushushu nenobushushu obuphezulu. I-carbon ye-carbon yentsimbi eyenziwe kwi-A234 ihlala inikezelwa kwifom ye-Butet-Welting ngokungqinelana ne-ASME B16.9 okanye i-ASME B16.49. Kukho amanqaku amabini e-carbon amabakala: i-WPB kunye ne-WPC, apho i-ATTM A234 WPB ihlala isetyenziswa kumzi-mveliso wepayipi. I-A234 WPB ye-A234 WPB ye-WOTB-WOIL ye-Welbows ibandakanya izithombe, ukugoba, ibuyise, i-tees, i-CAPS, i-rock, i-niples kunye nokuhlangana.

Umahluko ophambili phakathi kwe-caps yentsimbi engenasitayile kunye ne-carbon ye-carbon ye-carbon ngumohluko kwimpahla. Iichemicals eziqulathwe kwi-caps zentsimbi engenasitali ziya kugcina umphezulu we-cap ukusuka kwi-rusting kunye nokufumana ixesha elide.

Ukuze udlulisele umbhobho, kuyimfuneko ukususa i-hose ethe tye ngombhobho. Xa usebenzisa imibhobho eyahlukeneyo, kufuneka isetyenziswe ngemibhobho eyahlukeneyo. Xa kusetyenziswa umbhobho, i-elbow kufuneka isetyenziselwe ukutshintsha ubungakanani bombhobho. Xa ukubhabha, umbhobho weendlela ezintathu kusetyenziswa xa i-pipeling eyahlukeneyo ye-pipeling kunye nokwanda kokuhamba kwexesha elide kunye nokwandiswa komgangatho obandayo kunye nolwandiso olubi kakhulu kunye nolwandiso olubandayo olusetyenziselwa ukunxibelelana nombhobho. , Ekuqhagamsheleni nezixhobo ezahlukeneyo, kukho i-quadriday kunye neeplagi zesigaba sesixhobo.

Zonke iindlela eziqhelekileyo ze-welding zinokusetyenziselwa i-Weld Dotelloy C-276 Alloty, nangona inkqubo ye-oxyacetylene ayicetyiswa. Izilumkiso ezizodwa kufuneka zithathwe ukuthintela igalelo eligqithisileyo.

Emva kokwenza ubushushu obuphakathi, amaqondo athobekileyo athobelwe kubushushu obungaphantsi koluhlu oluchanekileyo phantsi kweemeko ezifanelekileyo zokuthintela isiphene esibonakalayo esibangelwa kukuphola ngokukhawuleza, kodwa kungekho mazwi aphezulu. Amaqondo obushushu atyhafileyo achaziweyo yintsimbi (inxalenye) yobushushu. Izixhobo ezihluthwe ngamandla kufuneka ziphathwe ngokomhlathi 7 kwinkcazo ye-A960 \ / A960m.

I-Chromium inika ukumelana nokunganyangeki kwe-sulfur computers kwaye inike ukumelana neemeko ze-oxiding kumaqondo obushushu aphezulu okanye kwizisombululo zonyango.

I-S31600 i-S31600 ithathelwa ingqalelo umbhobho webanga laselwandle kwaye yenzelwe ngaphandle kwazo naziphi na ii-wels okanye umthungo. Ibakala lenza kakuhle kwimithombo yeendaba eyahlukileyo emanzi kwaye ibonisa ukumelana nokungakhathali yi-chloride kunye nakuphi na ukungcola. I-chemistry ephezulu kweli ibanga lithintela imibhobho yexesha elide kwimizimba yamanzi. Nangona kunjalo, imibhobho yeBanga laseMali laManyano lichaphazeleka kumanzi afudumeleyo.

I-ASTM A234 WP23 WP22 WP22 WP22 WP22 WP22 WP22 ASTTIONS yenziwa yi-carbon, i-manganese, silicon, i-selfur, phospur, phospduur, i-chromium kunye ne-molybdenum ekwemo kwawo. Umxholo we-molybdenum yi-0.9-1% yokwenziwa kwenqanaba elenza le mali. Eli nqanaba linaba amandla e-thenlile le-380MPA elincinci kunye namandla esivumo se-585MPA encinci.

Ibanga lama-316ti liqulethe inani elincinci le-titanium. Umxholo wesitatium uhlala ujikeleze i-0.5%. I-titanium inza i-316 kumaqondo obushushu angaphezulu kwe-800¡ct.

I-Super Alfs ikwabizwa ngokuba ziintsebenzo zomsebenzi ophakamileyo. Zineento ezininzi kwindibaniselwano eyahlukileyo edaliweyo ukubonelela ngeepropathi ezikhethekileyo zezinto ezithile.

Ukuze udlulisele umbhobho, kuyimfuneko ukususa i-hose ethe tye ngombhobho. Xa usebenzisa imibhobho eyahlukeneyo, kufuneka isetyenziswe ngemibhobho eyahlukeneyo. Xa kusetyenziswa umbhobho, i-elbow kufuneka isetyenziselwe ukutshintsha ubungakanani bombhobho. Xa ukubhabha, umbhobho weendlela ezintathu kusetyenziswa xa i-pipeling eyahlukeneyo ye-pipeling kunye nokwanda kokuhamba kwexesha elide kunye nokwandiswa komgangatho obandayo kunye nolwandiso olubi kakhulu kunye nolwandiso olubandayo olusetyenziselwa ukunxibelelana nombhobho. , Ekuqhagamsheleni nezixhobo ezahlukeneyo, kukho i-quadriday kunye neeplagi zesigaba sesixhobo.

Intsimbi ye-348 intsimbi engenasimo yi-Aultiuthi yeBanga le-Austititic efumanekayo ngendlela yombhobho, ityhubhu, i-pubing, iflethi, i-valves, i-valuenes kunye neeplate.

Umahluko ophambili phakathi kwe-caps yentsimbi engenasitayile kunye ne-carbon ye-carbon ye-carbon ngumohluko kwimpahla. Iichemicals eziqulathwe kwi-caps zentsimbi engenasitali ziya kugcina umphezulu we-cap ukusuka kwi-rusting kunye nokufumana ixesha elide.

Imoda 400 yi-Alopper-Cop (malunga ne-67% Ni ¨C 23% Cu) i-Suressions ePhezulu kunye neSoftwards. I-Decility elungileyo kunye nokuphumelela kwe-thermal kufanelekile kwizicelo zamanzi aselwandle.

I-Dotelloy B-3 i-nickel-molybdenum ye-Alo Allocy ngokuchaseneyo nokungavisisani kunye nokunyanzelwa kunye nokuzinza koxinzelelo lwe-alloy b-2. Ukongeza, le alloty-yentsimbi ixhaphake kakhulu kumgca wokuhlaselwa ngumsebenzi kunye nokuhlaselwa kobushushu.

I-HT Pipe ibonelela ngoluhlu olupheleleyo lwemibhobho yokufakelwa njenge-carbon yensimbi, i-carbon yentsimbi, i-carbon stee, i-carbon stees, i-carbon stie stib stibs kunye ne-carbon stib stibs kunye ne-carbon stib stribs. I-carbon yekharbon okanye i-slege ethobekileyo ye-flanger efakwe iflethi, i-Wild Welds, iflethi ye-slip, iflethi ye-Weld, iFlenges, iFlenges, iplagi flanges. Sijongene nemveliso yokufakelwa kwemveliso yobukhulu obukhethekileyo kunye nemilo yesiko labathengi bethu.

I-ASTM A403 WP32 I-WPILS PAILS ithetha ukuba yeyiphi i-pie esebenzayo ukuba yeyiphi i-austinitic engabantu, isetyenziselwa iindlela zoxinzelelo zokulinganisa kunye neqondo lobushushu.

I-304 igubungela umgangatho we-Austetitac Stainess yentsimbi yentsimbi yezicelo zoxinzelelo. Izinto ezibonakalayo zemibhobho ziya kubandakanya ukuxolela, imivalo, ipleyiti okanye imibhobho ye-welday. Ukusebenza okanye ukwenza imisebenzi kuya kwenziwa ngokusuka, ukucinezela, ukubhoboza, ukuphelisa, ukugoba, ukuntywila, ngaphezulu kwemisebenzi emibini. Zonke izinto zezinto kufuneka zibe ngumfuziselo.

Izixhobo ezifana ne-ASTM A815 engaphakathi kwe-S32205 i-radius ye-radius isetyenziswa kumashishini olwandle, ioyile kunye ne-oyile yeoyile ye-oyile, kwaye irhasi ye-oyile, kwaye ixhaphake kwi-acid kunye ne-chloride i-ions.

Izixhobo zombhobho ziyafumaneka ngeendlela ezahlukeneyo ezifana nezixhobo ze-elbow, ukubuyela kwi-fittings, imibhobho yombhobho, i-ping phumela i-pie, i-pie ye-pie ye-pie, i-stub yokuphela kwe-pied, kunye ne-pieb yokuphela kwe-pie, kunye nemibhobho ye-pub. Elinye lale fomu linendima yabo yokudlala njengezixhobo zombhobho kodwa zinenjongo yokwandisa isixhobo sombhobho kwiimeko ezahlukeneyo.

I-MSSS-SP75 i-radius ende, i-3r ye-3r, i-tees ethe tye, ukunciphisa i-Tees, i-COPS, ubukhulu be-SCH5S-schxxs

I-Intloy 800 ye-Poule File, ixhaphake kumanzi olwandle kunye namanzi etyuwa manzi nangokupheliswa kweemeko.

I-Stainess yentsimbi 316 yezixhobo zeqhwa yimveliso eyenziwe ngeBanga le-316. Ikwabizwa ngokuba yiBanga laselwandle. Ezi zi-S31600 ze-S31600 ze-SS zithi zinokuba neepropathi ezingcono kunye nokungaxhathisi kunamanye amabakala ensiza engenazibala. Nangona izithembiso ezingenazitali zihlala zibizwa ngokuba zii-austetitic steels, kunye neChckel kunye neChokel Alloses SA403 WPOS STOSBDUM yongezwa kwiziphelo zokuphucula ukususwa kwayo ekuphuculeni ukunganyangeki.

Nangona kunjalo, i-titanium inokuphulukana namandla ayo kumaqondo obushushu angaphezulu kwe-430?
