Intshayelelo
Amacandelo okuvelisa umbane eRashiya, ukucocwa kweoyile kunye neekhemikhali zepetroli ayaqhubeka nokuphuculwa rhoqo kunye nokwandiswa kwamandla, nto leyo eqhuba imfuno enkulu yeenkqubo zemibhobho ye-alloy enobushushu obuphezulu, enoxinzelelo oluphezulu. Imibhobho yentsimbi yekhabhoni eqhelekileyo idla ngokuba neengxaki zokuguquguquka kwe-creep kunye nokungaphumeleli kwe-oxidation phantsi kweemeko ezihlala zishushu kakhulu, nto leyo eyenza intsimbi ye-alloy ye-chromium-molybdenum (chrome-moly) ibe yeyona nto ikhethwayo kwinkonzo ebalulekileyo yobushushu obuphezulu.
I-ASTM A335ngumgangatho owaziwayo kwihlabathi liphela weepayipi zentsimbi ze-ferritic chrome-moly alloy ezingenamthungo ezenzelwe ukusebenza ngobushushu obuphezulu kunye noxinzelelo oluphezulu. Njengomthengisi wempahla oqeqeshiweyo kunye nomrhwebi ogxile kwizisombululo zemibhobho yemizi-mveliso, iSANONPIPE igcina uluhlu olubanzi lwezintoImibhobho ye-ASTM A335kuzo zonke iiklasi eziqhelekileyo, kunye namaxwebhu axhasayo apheleleyo kunye neendlela zokuhambisa ezilungiselelwe iiprojekthi zaseRashiya. Sinceda abathengi ukuba bakhethe iklasi ye-alloy efanelekileyo ukuze ihambelane neemeko zabo zokusebenza kwaye sinciphise amaxesha okufumana.
Yintoni i-ASTM A335 Standard?
I-ASTM A335 / ASME SA335yinkcazo eqhelekileyo yeepayipi zentsimbi ye-ferritic alloy ezingenamthungo ezenzelwe inkonzo yobushushu obuphezulu kunye noxinzelelo oluphezulu. Igubungela uthotho lwee-alloy grades eziqiniswe zi-chromium kunye ne-molybdenum ezongeziweyo, ezibonelela ngokumelana okuphezulu kakhulu nokuqhekeka, ukumelana ne-oxidation kunye namandla obushushu obuphezulu xa kuthelekiswa nentsimbi eqhelekileyo yekhabhoni efana neI-API 5L Ibanga B.
Zonke iipayipi eziphantsi kwalo mgangatho kufuneka zenziwe ngolwakhiwo olungenamthungo kwaye ziphathwe ngobushushu obulawulwayo (ukulungisa + ukufudumala, okanye ukucima + ukufudumala kwiigreyidi eziphezulu ze-alloy) ukuze kufezekiswe ulwakhiwo olufunekayo lwe-ferritic microstructure kunye neempawu zoomatshini ezizinzileyo. Zenzelwe ukusebenza ixesha elide kwiimeko apho intsimbi yekhabhoni ingenakumelana noxinzelelo lobushushu oluqhubekayo.
AmaBanga aPhambili kunye nee-Russian GOST Equivalents
I-SANONPIPE inezona ntlobo ze-ASTM A335 ezisetyenziswa kakhulu kwimarike yaseRashiya, nganye inexabiso elilinganayo elamkelekileyo phantsi komgangatho waseRashiya we-ГОСТ 550 weepayipi zentsimbi ye-alloy engenamthungo. Iimpawu zaseRashiya ziphawulwe kwiIsiRashiyaukuze kube lula ukubhekisela kwiinjineli zasekuhlaleni kunye namaqela okuthenga.
