Yintoni i-STPG 370 Pipe Material?

I-STPG 370 ludidi lombhobho wentsimbi olunekhabhoni ephantsi oluchazwe kwi-JIS G 3454 esemgangathweni yaseJapan.

I-STPG 370 inamandla okutsalwa angaphantsi kwe-370 MPa kwaye amandla okutsalwa angaphantsi kwe-215 MPa.

I-STPG 370 ingenziwa njengeetyhubhu zentsimbi ezingenamthungo okanye iityhubhu zentsimbi ezidityanisiweyo kusetyenziswa inkqubo yokufakelwa kwe-electric resistance welding (ERW). Ifanelekile ukusetyenziswa kwiinkqubo zemibhobho yoxinzelelo ezinamaqondo obushushu asebenzayo afikelela kwi-350°C.

Okulandelayo, siza kujonga i-STPG 370 kwiinkqubo zokuvelisa, ukwakheka kweekhemikhali, iimpawu zoomatshini, uvavanyo loxinzelelo lwe-hydrostatic, uvavanyo olungonakalisiyo, kunye nokufakwa kwe-galvanized.

Inkqubo yoMveliso

I-JIS G 3454 STPG 370 ingenziwa kusetyenziswaingenamthungo or I-ERWinkqubo yokuvelisa, idityaniswe neendlela ezifanelekileyo zokugqiba.

Ukwenziwa kweeKhemikhali

I-JIS G 3454ivumela ukongezwa kwezinto zeekhemikhali ezingekho kwitheyibhile.

I-STPG 370 yintsimbi ekhabhoni ephantsi ngokweekhemikhali zayo. Ukwakheka kwayo kweekhemikhali kwenzelwe ukuba isetyenziswe kwiindawo ezingadluli kwi-350°C, enamandla, ukuqina, kunye nokumelana nobushushu obuphezulu.

Ukongeza kumandla okutsalwa, amandla okutsalwa, kunye nobude obukhankanywe apha ngasentla, kukwakho novavanyo lokuthamba kunye nokugoba.

Uvavanyo lokuTyatya: Xa umgama phakathi kweepleyiti ezimbini ufikelela kumgama ochaziweyo u-H, akusayi kubakho ziphene okanye imingxunya kumphezulu wombhobho wentsimbi.

Ukugoba: Umbhobho kufuneka ugotywe ngama-90° kwi-radius ephindwe kathandathu ububanzi bawo bangaphandle. Udonga lombhobho kufuneka lungabi naziphene okanye iintanda.

Uvavanyo lwe-Hydrostatic okanye uvavanyo olungonakalisiyo

Umbhobho ngamnye wentsimbi uvavanywa nge-hydrostatic okanye uvavanyo olungatshabalalisiyo ukujonga naziphi na iziphene ezingabonakaliyo emehlweni.

Uvavanyo lwe-Hydrostatic

Ngokwenqanaba elicwangcisiweyo lobukhulu bodonga lombhobho wentsimbi, khetha ixabiso elifanelekileyo loxinzelelo lwamanzi, uligcine ubuncinane imizuzwana emi-5, kwaye ujonge ukuba umbhobho wentsimbi uyavuza na.

Itheyibhile yobunzima bombhobho wentsimbi ye-JIS G 3454 kunye neshedyuli yoMbhobho inokubonwa ngokucofa ikhonkco elilandelayo:

· Itshati yoBunzima bePipe yeNsimbi yeJIS G 3454

· ishedyuli 10,ishedyuli 20,ishedyuli 30,ishedyuli 40,ishedyuli 60kunyeishedyuli 80.

Uvavanyo olungatshabalalisiyo

Ukuba kusetyenziswa uhlolo lwe-ultrasonic, kufuneka lusekelwe kumgangatho ongqongqo kunomqondiso weklasi ye-UD kwi-JIS G 0582.

Ukuba kusetyenziswa uvavanyo lwe-eddy current, kufuneka lusekelwe kumgangatho ongqongqo ngakumbi kunesignali yeklasi ye-EY kwi-JIS G 0583.

I-Galvanised

Kwi-JIS G 3454, imibhobho yentsimbi engagqunywanga ibizwa ngokubaimibhobho emnyamakwaye imibhobho yentsimbi egalelweyo ibizwa ngokubaimibhobho emhlophe.

Umbhobho omhlophe - umbhobho wentsimbi oqinisiweyo

Umbhobho omhlophe: umbhobho wentsimbi egalelweyo

Umbhobho omnyama - umbhobho wentsimbi ongenamagalelo

Umbhobho omnyama: umbhobho wentsimbi ongagalelwanga ngesinyithi

Inkqubo yemibhobho emhlophe kukuba imibhobho emnyama efanelekileyo idutyulwe okanye iphoswe ukuze kususwe ukungcola kumphezulu wombhobho wentsimbi ize igqunywe nge-zinc ehambelana nomgangatho we-JIS H 2107 ubuncinane webanga loku-1. Eminye imicimbi yenziwa ngokuhambelana nomgangatho we-JIS H 8641.

Iimpawu zomgqumo we-zinc zijongwa ngokuhambelana neemfuno ze-JIS H 0401, iNqaku 6.

Ngathi

Ukususela oko yasekwa ngo-2014,Intsimbi yeBotopiye yaba ngumthengisi ophambili wemibhobho yentsimbi yekhabhoni eMntla China, eyaziwa ngenkonzo egqwesileyo, iimveliso ezikumgangatho ophezulu, kunye nezisombululo ezibanzi.

Le nkampani inikezela ngeendidi ngeendidi zeepayipi zentsimbi yekhabhoni kunye neemveliso ezinxulumene nazo, kuquka ipayipi yentsimbi engenamthungo, i-ERW, i-LSAW, kunye ne-SSAW, kunye noluhlu olupheleleyo lwee-fittings zepayipi kunye nee-flanges. Iimveliso zayo ezikhethekileyo ziquka ii-alloys ezikumgangatho ophezulu kunye neentsimbi ezingenasici ze-austenitic, ezenzelwe ukuhlangabezana neemfuno zeeprojekthi ezahlukeneyo zepayipi.
