Fittings rau HDPE kav (HDPE - tsis tshua muaj siab polyethylene) yog ib qho tseem ceeb uas yuav tsum tau ua kom muaj kev txuas ntxiv thiab dhau ntawm cov kav dej. Lawv xav tau qhov tsim nyog los txuas cov kav dej sib txawv lossis cov khoom siv, nyob rau hauv qhov chaw uas lawv tig los yog ceg, nrog rau thaum ua haujlwm kho cov kav dej polyethylene.
Fittings rau HDPE kav yog tsim los ntawm tib yam khoom raws li cov kav dej. Nws muaj ntau qhov zoo dua li lwm tus: nws tiv taus cov tshuaj thiab deformations, qhov kub thiab txias; tsis xeb lossis oxidize; tsis decompose thiab pab ntau tshaj 50 xyoo; yog lub teeb yuag thiab ib puag ncig tus phooj ywg.
Lub ntsiab hom fittings rau installation ntawm polyethylene kav:
- cast;
- welded;
- electrowelded;
- compression.
Fittings rau HDPE kav cam khwb cia (SPIGOT)
Tshuaj nyob rau hauv siab los ntawm casting, raug lawv mus rau machining ntxiv. Lawv siv nyob rau hauv txhua hom kev sib txuas. Cam khwb cia fittings yog resistant rau tshuaj aggressive ib puag ncig, tsis txhob oxidize thiab tsis hloov txoj kab uas hla. Txuaglos ntawm kev tshem tawm cov khoom tso rau hauv cov phab ntsa kav dej.
Fittings rau HDPE kav welded (segmental)
Tsim los txuas cov yeeb nkab ntu ntawm lawv cov khoov thiab ceg; nyob rau hauv cov pob qij txha ntawm cov kav dej sib txawv diameters los yog nrog fittings. Kev sib txuas yog tsim los ntawm pob tw thiab electrofusion vuam.
Electric welded HDPE yeeb nkab fittings
Ua tau raws li qhov siab los ntawm kev nrum thiab muaj hluav taws xob kauv sab hauv, uas, thaum cua sov, yog hermetically txuas nrog cov yeeb nkab. Fittings ntawm hom no muaj ib tug bar code uas qhia txog qhov yuav tsum tau nro thiab lub sij hawm yuav tsum tau rau ib tug ruaj khov foob.
Lawv siv los kho cov kav dej hauv av, hauv cov phab ntsa thiab qab nthab. Kev sib txuas yuav tshwm sim siv lub tshuab vuam tshwj xeeb, uas tso cai rau koj los teeb tsa qhov tsim nyog rau cua sov.
Compression fittings rau HDPE kav
Ib hom fittings yooj yim heev, raws li lawv tau tsim los npaj siv. Cov yeeb nkab tsis xav tau kev npaj ua ntej, thiab kev sib khi tshwm sim yam tsis muaj lub tshuab vuam thiab lwm yam khoom siv, ib qho tseem ceeb ntawm cov hlau los yog yas compression txaus. Nrog tus qauv txiv neej thiab poj niam threads, cov fittings no haum rau kev sib txuas cov kav dej ntawm cov khoom sib txawv.
Sib dhos thiab disassembly ntawm compression haum tuaj yeem ua tiav txog kaum zaug, thaum nws tsis poob nws qhov zoo, thiab hauv rooj plaubkho, nws txaus los hloov cov khoom sab hauv nrog tus yuam sij.
Tsis muaj corrode kiag li, vim nws tsis muaj cov hlau. Tsim nyog rau kev thauj khoom noj thiab dej haus vim tias txhua qhov chaw yog ua los ntawm cov khoom siv tu cev.
Txhua qhov fittings rau HDPE kav yog muaj nyob rau hauv daim ntawv ntawm tees, luj tshib, sab hauv thiab sab nraud threads, thiab lwm yam., thiab lub hauv paus ntsiab lus ntawm kev twb kev txuas yog zoo li lub installation ntawm hlau-yas kav. Qee lub sij hawm nws raug pom zoo kom siv sealant ntawm qhov sib txuas ntawm qhov sib txuas thiab sealant.
