ASTM A234simbi yakajairikapombi fittingsyakashandiswa zvakanyanya mumapombi masisitimu, inosanganisira kabhoni simbi uye alloy simbi zvinhu.

Chii chinonzi Steel pipe fittings?
Simbi pombi fitting inogadzirwa nekabhoni simbi kana alloy simbi pombi, mahwendefa, profiles, kune imwe chimiro chinogona kuita basa (Shandura mafambiro emvura kana chiyero) mumapombi masisitimu.Kunyanya izvi zvigadziriso zvinosanganisira simbi gokora (45 kana 90 dhigirii bend), tee, reducer (concentric kana eccentric reducer), muchinjiko, caps, nipple, flanges, gasket, studs uye nezvimwe.

Nezvinangwa zvemaindasitiri, mumapombi masisitimu kazhinji tinoda kushandura nzira yekufambisa;Rongedza zvinwiwa (mafuta uye gasi, mvura, slurry) chiyero chekuyerera;Vhura kana kuvhara mapaipi, nezvimwewo. Saka kuti upedze mabasa aya, simbi yepombi fittings ichaiswa.

Chii chinonzi ASTM A234 WPB?
ASTM A234 ndiyo Yakajairwa Kutsanangurwa kwesimbi pombi fittings inosanganisira kabhoni simbi uye alloy simbi zvinhu zvine mwero uye yakakwirira tembiricha masevhisi.Inovhara simbi dzesimbi dzemhando dzisina musono uye dzakasungwa.Simbi Pipe fittings inoshandiswa mumapombi ekumanikidza uye mukumanikidza ngarava machira.Izvi zvekugadzirisa zvinhu zvinosanganisira simbi yakaurayiwa, forging, mabara, mahwendefa, isina musono kana HFW (fusion welded) zvigadzirwa zvepombi, nesimbi yekuzadza yakawedzerwa.

ASTM A234 inosanganisira yakarukwa kabhoni simbi uye alloy simbi yekumisikidza isina musono uye yakasungwa chivakwa chakafukidzwa nekuvandudzwa kweASTM B16.9, B16.11, MSS-SP-79, MSS-SP-83, MSS-SP-95, uye MSS. -SP-97.etc.

Sezvatinoziva, ASTM A234 simbi pombi fittings inoshandiswa mukumanikidza pombi uye mukumanikidza ngarava kugadzira, kune masevhisi ane mwero uye akakwira tembiricha.Zvinhu zvekuisa mune iyi chiyero zvinosanganisira simbi yakaurayiwa, forging, mabara, mahwendefa, isina musono kana fusion-welded tubular zvigadzirwa zvine simbi yekuzadza yakawedzerwa.
Mune iyi chiyero inovhara iyo yakatarwa yemagokora, tei, zvinoderedza, caps uye muchinjiko, inowanzotora butt welding ends.

Simbi pombi fittings yekugadzira mhando mune forged, threaded, butt weld, uye isina musono.

Magiredhi muASTM A234:

ASTM A234 tsananguro ine mamakisi akawanda, akadai seWPB, WPC, WP5, WP9 WP11, WP12, WP22, WP91 zvichingodaro.
Mune aya akajairwa Giredhi WPB ndiyo inonyanya kushandiswa mapombi epakati uye epamusoro tembiricha.W zvinoreva weldable, P zvinoreva pressure, B igiredhi b, kureva kushoma goho simba.
Kunobva zvinhu zvakasvibirira zveASTM A234 WPB simbi pombi fittings zvinogona kubva simbi pombi, akadai ASTM A106 Gr.B uye C. Zvakare kubva simbi ndiro, sezvo ASTM A285 Gr.C, ASTM A516 Gr 70, ASTM A572 etc.

ASTM A234 WPB simbi pombi inokodzera makemikari uye michina maficha:
1) Giredhi WPB fittings akagadzirwa kubva simbi pombi kana mahwendefa anonyanyisa C i 0.35%.
2) Forging fittings Carbon yemukati 0.35% yakanyanya uye Silicon yemukati 0.35% yakanyanya, hapana hushoma.
3) Pakuderedzwa kwega kwega kwe0.01 yeCarbon zvirimo, Manganese yepamusoro yemukati inowedzera 0.06%, kusvika pakakwirira 1.35% yeMn.
4) Copper, nickel, Niobium uye Molybdenum sum content haifaniri kudarika 1.00%.
5) Niobium + Molybdenum haifaniri kudarika 0.32%.

Mechanical zvimiro zveASTM A234 WPB pombi fittings:

ASTM A234 inosanganisira isina musono uye welded pombi fittings:
Papombi dzesimbi dzisina musono dzinoreva midziyo yakabikwa kubva papombi dzesimbi isina musono uye machubhu;Saka pombi dzesimbi dzakasungwa dzinovhara mbichana kubva papombi dzesimbi dzakasungwa.
Zvinozozivikanwa kuti,
Kutsanangurwa kweASTM A234 haifukidze masimbi ekuisa welding kana mafittings akagadzirwa kubva kucastings.

Simbi pombi fittings kugadzira maitiro ekugadzira:
Maitiro ekugadzira ekugadzirisa pombi zvinosanganisira kugadzira uye kuumba mashandiro.Zvakare kudzvanya, kusando, kuboora, extruding, kugumburisa, kukunguruka, kukotama, fusion welding uye machining.Kana maitiro ekusanganisa maviri kana anopfuura emabasa aya.

Munguva yekugadzira simbi pombi fittings, pazasi zviitiko zvichacherechedzwa:
1) Kusakwana kunokuvadza, hurema hwekushongedza hauzosikwe.
2) Mushure mekugadzira kana kugadzira mafittings mutembiricha yakakodzera, inotonhodzwa munzvimbo yakakodzera kune tembiricha iri pasi peiyo yakakosha.Uye hapana hurema huchaitwa panguva yekutonhora.Kukurumidza kutonhora hakufaniri kudarika mumhepo.
3) Kuongororwa kwakakodzera kuchaitwa mushure mekugadzira.(Hydrostatic bvunzo, kuomarara bvunzo, tensile bvunzo nezvimwe)
