Carbon Steel National Standard Gate Valve

Isu tiri nyanzvi yekugadzira valve ine ISO, API uye CE certification. Isu tine zvivakwa zvekugadzira zvepamberi uye takanyatso kudzora mhando mune yega maitiro. Isu tinotora maOEM neODM maodha, uye MOQ yedu inochinjika kune ese marudzi emapurojekiti. Mavharuvhu edu anotengesa kumisika pasi rese, uye vatengi vanogara vachiisa maodha ekudzokorora nekuda kwemhando yedu yakavimbika.

Ndeapi maitiro ayo mavharuvhu emagedhi anowanzo kutevedzera?

Mavharuvhu egedhi akavakwa kune akasiyana mazinga, zvichienderana nekuti uye kupi uye nemashandisiro auchaashandisa. Kune inorema maindasitiri uye oiri & gasi mapurojekiti, API 600 ndiyo yakanyanya kugamuchirwa mwero. Inotonga dhizaini yevharuvhu, sarudzo dzezvinhu uye miedzo yekumanikidza. ISO 6002 ndeimwe chiyero chepasi rose chinoenderana neAPI 600 yebhoneti simbi yegedhi mavharuvhu, isu tichiteverawo China's GB/T 12234 yenyika standard. Zvese izvi zviyero zvinotsanangura saizi, kuita uye kuchengetedza zvinodiwa, kuvimbisa kuisirwa kwakakodzera uye kugadzikana kushanda kwenguva refu.

Hunhu Hunokosha

Unogona here kutsanangura izvo API 600 yakajairwa inovhara?

API 600 chiyero cheindasitiri chakaburitswa neAmerican Petroleum Institute. Inonyanya kushanda kune akabhodha bonnet simbi yegedhi mavharuvhu, ayo anoshandiswa zvakanyanya mukunatsa, oiri & gasi mapaipi uye mamwe mamiriro ekushanda akaomarara. Iyi chiyero inotonga kusarudzwa kwezvinhu, dhizaini dhizaini, maitiro ekugadzira uye akasiyana siyana ekumanikidza & tightness bvunzo. Inovimbisa kuti valve yega yega inogona kumira zvakasimba kudzvinyirira, kupisa kwepamusoro uye midhiya yakaoma mukushanda kwemunda chaiwo. Kana vheji yegedhi ikasangana neAPI 600, inovakwa kuti igare mukukosha, inoda kuseta.

WCB yemhando ipi yezvinhu zvemiviri yevharuvhu?

WCB yakajairika yakakandwa kabhoni simbi giredhi pasi peASTM A216, pfupi ye "Weldable Giredhi B Cast Carbon Steel." Ndiyo imwe yesarudzo dzakakurumbira dzemiviri yevharuvhu nekuti inoenzanisa simba, weldability uye inodhura chaizvo. WCB inoshanda kune akawanda akajairika maindasitiri anoshandiswa, anosanganisira mvura, oiri, gasi uye mitsara yeutsi, uye inobata tembiricha kubva -29°C kusvika 425°C. Iyo yakasimba, iri nyore kukanda mumhando dzakaoma, uye inoshanda nehupamhi hwekumanikidza ratings.

Ndeupi rudzi rwevhavha yegedhi inonyanya kushandiswa muindasitiri?

Wedge gedhi vharuvhu ndiyo yakanyanya kunyanyozivikanwa mhando mumapaipi emaindasitiri. Iine dhisiki rakaita seweji rinotsvedza pakati pezvigaro zviviri kuti rivhure kana kuvhara kuyerera, richigadzira chisimbiso chakasimba kana chakavharwa zvizere. Iyo dhizaini iri nyore uye yakavimbika, uye inoshanda nemazvo kune yakanyanya kudzvanywa uye tembiricha mazinga. Iwe unovawana munzvimbo dzekuchenesa mvura, zviteshi zvemagetsi, zvivakwa zveoiri uye gasi, uye zvidyarwa zvemakemikari-ndizvo zvekuenda kune mazhinji-on-off control mabasa.
