A234 wpb sch 80 ewwn imapezekanso pamtundu waukulu. Cholinga chogwiritsa ntchito Astm A234 gr wpb erdow ndikusintha njira kapena kuyenda munjira yopumira.

Pofuna kufafanizira mapaipi, ndikofunikira kuchotsa payipi yolunjika pa mapaipi. Mukamagwiritsa ntchito ma piipelines osiyanasiyana, mapaipi osiyanasiyana ayenera kugwiritsidwa ntchito. Pamene mapaipiwo amagwiritsidwa ntchito, chikopa chiyenera kugwiritsidwa ntchito kusintha kukula kwa mapaipi. Mukamacheza, chipika chanjira zitatu chowonekacho chimagwiritsidwa ntchito ngati cholumikizira cholumikizira, kuti chikhazikitse chipani cholumikizirana kapena kukula kwa nthawi yayitali komanso cholumikizira cholumikizira cha mapaipi. , Pakulumikizana ndi zida zosiyanasiyana, palinso zolumikizira ndi mapulagini a gawo la chida.

Kalasi yachitsulo iyi ndi ya sing'anga ya sing'anga komanso imakhalanso ndi manganese, phosphorous, sulufule ndi silicon.

Zizindikiro za Astme Astme A234 Zikakhala ndi Maphunziro ambiri, monga wpb, wpc, wpc, wp5, wp91, wp12, wp22, wp82, wp81. Pali magawo a ASM ASM A234 WPB chitoliro mu 1 \ / mainchesi mpaka mainchesi 24 mainchesi awiri ometa ndi makoma osiyanasiyana omwe amagwirizana ndi zigawo.

Imakwirira zolimba zamitundu yosalala komanso yowoneka bwino. Zovala zachitsulo ziphuphu zimagwiritsidwa ntchito pokakamiza mapaipi ndipo mumakakamizidwa ndi zitoliro zoyenererana, kuphatikizapo zitsulo za a AstB Asme B16.9, B16.11, MS-79, MS-83, SS-95, ndi SSS.

Mukamalumikiza magawo amenewa, ikani gasiketi pakati pa ma flanges awiri, kenako ndikulimbana ndi zomangira, kotero awiriwo adzalumikizidwa pamodzi mwamphamvu.

Timatulutsa zitsulo za kaboni A105 \ / / / / / / / / / / / / / / / Alc5n FRORE Malingaliro opambana pakukakamizidwa ndi magwiridwe antchito ngati Hydraulic Exting Pakatikati.

Mtundu wolumikizira wokhazikika nthawi zambiri umabwera ndi mayunitsi awiri, ndi gasket ndi ma bolts ena & mtedza kuti mulumikizane. .

A350 LF3 yozungulira ikufuna padziko lonse lapansi chifukwa chokana kwambiri monga kukana kuwonongeka, kumalibeni, kulimba komanso kulondola kwakanthawi.

Njira yokhululukirira imaphatikizanso zinthuzo kuti zipangire mawonekedwe achipongwe. Chogulitsacho chimapangidwa pambuyo pake kwa mawonekedwe ndi kukula kwa njira yomalizidwa.

Zitsulo zopangira zimapereka mwayi woyenera kuyeretsa, kuyeserera kapena kusintha. Nthawi zambiri amabwera motsatana koma amathanso kubwera m'magulu osiyanasiyana komanso amakona. Ma flanges amalumikizidwa wina ndi mnzake pobowola komanso wolumikizidwa ndi makina opukusa ndi kuwotcherera kapena kuluma ndipo amapangidwira kusokonekera kwamphamvu; 150lb, 300lb, 400lb, 600LB, 900LB, 1500LB ndi 2500Lb.

Kuwala kumatha kukhala mbale yophimba kapena kutseka kumapeto kwa chitoliro. Izi zimatchedwa Flange ya wakhungu. Chifukwa chake, zojambulazo zimawonedwa ngati zigawo zamkati zomwe zimagwiritsidwa ntchito pothandizira makina.

Onse a Sa234 WPB Erdow adapangidwa ku India ndikupangidwa kuchokera ku Europe yoopsa ku Europe. Onse a Astm A234 Elbow & Erbow A234 WPC amapangidwa kuchokera mbale, atapanikiza mbali ziwiri ndi ma halves awiri.

Zitsulo zopangira zimapereka mwayi woyenera kuyeretsa, kuyeserera kapena kusintha. Nthawi zambiri amabwera motsatana koma amathanso kubwera m'magulu osiyanasiyana komanso amakona. Ma flanges amalumikizidwa wina ndi mnzake pobowola komanso wolumikizidwa ndi makina opukusa ndi kuwotcherera kapena kuluma ndipo amapangidwira kusokonekera kwamphamvu; 150lb, 300lb, 400lb, 600LB, 900LB, 1500LB ndi 2500Lb.

Kuwala kumatha kukhala mbale yophimba kapena kutseka kumapeto kwa chitoliro. Izi zimatchedwa Flange ya wakhungu. Chifukwa chake, zojambulazo zimawonedwa ngati zigawo zamkati zomwe zimagwiritsidwa ntchito pothandizira makina.

ASME A234 WPB Piptings Carbon zitsulo zomwe zimagwiritsidwa ntchito kwambiri

ASTM A350 LF3 kaboni mbewa yozungulira imapangidwa ndikupangidwa pamitengo yapadziko lonse lapansi. Tili ndi katundu wokonzeka kutumiza kumadera ambiri a dzikolo. Izi Asther A350 LF3 Caboni chitsulo chozungulira zimapangidwa ndi ma grace overlos overlos.

Izi zimatchedwa kuti "likulu kuti likhale" mtunda wofanana ndi radius pomwe a Astm A234 gr wpb embo.

Mtedza ndi ma bolts akuwonetsa mphamvu zochepa. Komabe, chitsulo chofatsa chimasintha kwambiri. Kukweza kwakukulu ndi malo omwe amapanga zinthu zabwino pakuyenda ndi kuwotcherera. Palibe zinthu zosiyanasiyana - zomwe zimagwiritsidwa ntchito ngati othandizira, osati mitundu ina ya chitsulo, yomwe imapangitsa mtedza ndi ma bolts omwe amadziwika kuti ndi mtengo wotsika mtengo.

Kaboni mosadukiza, zomwe zimapangidwa molingana ndi Astherm A105, nthawi zambiri amagwiritsidwa ntchito popanga mapulogalamu. Izi zidapangitsa kuti zigawo zitsulo zosungunuka (kuphatikizapo zowongoka, zolimbitsa thupi, ndi mavuvu, ndi zina) zimagwiritsidwa ntchito ngati ntchito yozungulira- komanso yokwera kwambiri pakukakamizidwa.
