I-Carbon Steel yeSizwe yoMgangatho weSango iValve

Singumvelisi wevalvu oqeqeshiweyo onezatifiketi ze-ISO, API kunye ne-CE. Sinezixhobo eziphambili zemveliso kunye nokulawula ngokungqongqo umgangatho kuyo yonke inkqubo. Sithatha iiodolo ze-OEM kunye ne-ODM, kwaye i-MOQ yethu iguquguquka kuzo zonke iintlobo zeeprojekthi. Iivalvu zethu zithengisa kwiimarike kwihlabathi jikelele, kwaye abathengi bahlala befaka iiodolo eziphindaphindayo ngenxa yomgangatho wethu othembekileyo.

Zeziphi iinkcukacha ezidla ngokulandelwa ziivalvu zesango?

Iivalve zesango zakhiwe kwimigangatho eyahlukeneyo, kuxhomekeke apho kwaye uya kuzisebenzisa njani. Kwiiprojekthi ezinzima zemizi-mveliso kunye neoyile kunye negesi, i-API 600 ngowona mgangatho wamkelwe ngokubanzi. Ilawula uyilo lwevalvu, ukhetho lwezinto eziphathekayo kunye novavanyo loxinzelelo. I-ISO 6002 yenye umgangatho wamazwe ngamazwe ohambelana ne-API 600 yeevalvu zesango lentsimbi yebhonethi, ngelixa silandela i-GB / T 12234 yelizwe jikelele yaseChina. Yonke le migangatho ichaza ubungakanani, iimfuno zokusebenza kunye nokhuseleko, ukuqinisekisa ukufakela okufanelekileyo kunye nokusebenza okuzinzileyo kwexesha elide.

Iimpawu eziphambili

Ngaba unokucacisa ukuba umgangatho we-API 600 ugubungela ntoni?

I-API 600 ngumgangatho woshishino okhutshwe yi-American Petroleum Institute. Isebenza ikakhulu kwiivalvu zesango lentsimbi yebhonethi, ezisetyenziswa kakhulu kwiindawo zokucokisa, imibhobho ye-oyile kunye negesi kunye nezinye iimeko zokusebenza ezinzima. Lo mgangatho ulawula ukukhethwa kwezinto, uyilo lolwakhiwo, iinkqubo zemveliso kunye noxinzelelo olwahlukeneyo kunye novavanyo lokuqina. Iqinisekisa ukuba yonke ivalve inokumelana ngokuthe ngcembe noxinzelelo oluphezulu, ubushushu obuphezulu kunye nemidiya entsonkothileyo ekusebenzeni kwentsimi. Ukuba ivalve yesango idibana ne-API 600, yakhiwe ukuba ihlale kwindawo ebaluleke kakhulu, ifuna ukuseta.

Loluphi uhlobo lwemathiriyeli i-WCB yemizimba yevalvu?

I-WCB libakala eliqhelekileyo lokuphoswa kwentsimbi yekhabhoni phantsi kwe-ASTM A216, mfutshane kwi "Weldable Grade B Cast Cast Carbon Steel." Lolunye lolona khetho ludumileyo kwimizimba yevalvu kuba ilinganisa amandla, ukuwelda kunye neendleko kakuhle. I-WCB isebenzela uninzi losetyenziso lwemizi-mveliso ngokubanzi, kuquka amanzi, i-oyile, igesi kunye neentambo zomphunga, kwaye ibamba amaqondo obushushu ukusuka ku -29°C ukuya malunga ne-425°C. Yomelele, kulula ukuyiphosa kwiimilo ezintsonkothileyo, kwaye isebenza ngoluhlu olubanzi lweereyithingi zoxinzelelo.

Loluphi uhlobo lwevalve yesango olusetyenziswa kakhulu kushishino?

Ivalve yesango le wedge yeyona nto ixhaphakileyo kwimibhobho yeshishini. Inediskhi emile okwe wedge etyibilika phakathi kwezihlalo ezibini ukuvula okanye ukuvala ukuhamba, idala itywina eliqinileyo xa ivalwe ngokupheleleyo. Uyilo lulula kwaye luthembekile, kwaye lusebenza kakuhle kuninzi loxinzelelo kunye neqondo lokushisa. Uya kuzifumana kwiindawo zokucocwa kwamanzi, izikhululo zamandla, ioli kunye negesi, kunye nezityalo zekhemikhali-zihamba phambili kwimisebenzi emininzi yokulawula.
