W kuthetha ukubhala, ukuphoswa;
I-C-CARBON STEEL carbon steel, i-A, b, kunye ne-C ibonisa ixabiso lamandla ohlobo lwensimbi ukusuka kwi-low ukuya phezulu.
I-WCA, i-WCB, i-WCC imele i-carbon steel, enomsebenzi omhle we-welding kunye namandla omatshini.I-ABC imele inqanaba lamandla, iWCB esetyenziswa ngokuqhelekileyo.Impahla yombhobho ehambelana ne-WCB kufuneka ibe yi-A106B, kunye ne-forging material ehambelanayo yi-A105.Ilungele iivalve phantsi kobushushu obuqhelekileyo kunye noxinzelelo.
I-WC6 kukugalelwa kwentsimbi yealloyi.Inokumelana nobushushu obuphezulu kunye neempawu ze-antioxidant kwaye ifanelekile kwiivalvu phantsi kobushushu obuphezulu kunye neemeko zoxinzelelo oluphezulu.
Isixhobo sombhobho esihambelanayo simalunga ne-A355 P11, kunye nenxalenye yokubumba i-A182 F11;
Ukongeza, kukho i-WC9, i-high-temperature alloy steel, ehambelana malunga ne-A355 P22, kunye nokukhwabanisa kufuneka kuhambelane ne-A182 F22.
I-WC edityanisiweyo yokuphosa inamandla aphezulu kunye nokuqina.Ifanelekile kwizicelo zemizi-mveliso eziqhelekileyo.
I-LCB / LCC (ASTM A352) Intsimbi ye-carbon ephantsi yobushushu inobunzima obuphantsi kunye nokumelana nokubola.Ifanelekile kwizicelo zobushushu obuphantsi kwe-ultra -low, njenge-LPG yegesi yendalo (LNG).
Iivalvu zeZfa zivelisa iivalvu zebhabhathane zeWCB eziqhelekileyo kubathengi kwihlabathi liphela ngobushushu obuqhelekileyo, kwaye sinako ukuvelisa iivalve zebhabhathane zeLCC kubathengi abavela kuMantla Yurophu njengeRussia, iFinland njl.
ngasentla yiWCBChina wafer butterfly valvekunye neLCCChina lug butterflyivalve.
