Thaum qhov loj me yog qhov tseem ceeb thaum xaiv cov flanges, lub luj tshib, thiab lwm yam khoom ntawm koj cov txheej txheem kav, cov yeeb nkab kawg yog qhov tseem ceeb rau kev ua kom haum zoo, lub foob kaw ntom nti, thiab kev ua haujlwm zoo.

Nyob rau hauv phau ntawv qhia no, peb yuav saib ntau yam yeeb nkab kawg configurations muaj, cov xwm txheej lawv feem ntau siv nyob rau hauv, thiab yam uas koj yuav tsum xav txog thaum xaiv ib tug tshwj xeeb yeeb nkab kawg.

COMMON PIPE ENDS

Hom yeeb nkab kawg xaiv yuav txiav txim seb nws txuas mus rau lwm yam khoom siv thiab cov kev siv thiab cov khoom siv ntawm cov yeeb nkab yog qhov zoo tshaj plaws.

Cov yeeb nkab kawg feem ntau poob rau hauv ib qho ntawm plaub pawg:

• Plain Ends (PE)
• Threaded Ends (TE)
• Bevelled Ends (BW)
• Grooved Mechanical Joints lossis Grooved Ends

Ib lub yeeb nkab kuj tuaj yeem muaj ntau hom kawg.Qhov no feem ntau raug xaiv nyob rau hauv cov yeeb nkab piav qhia lossis daim ntawv lo.

Piv txwv li, 3/4-nti SMLS Schedule 80s A / SA312-TP316L TOE yeeb nkab muaj xov ntawm ib kawg (TOE) thiab yog dawb ntawm lwm qhov.

Hauv qhov sib piv, 3/4-nti SMLS Teem Sij Hawm 80s A / SA312-TP316L TBE yeeb nkab muaj xov ntawm ob qhov kawg (TBE).

PLAIN END (PE) PIPE siv thiab txiav txim siab

PE kav dej muaj qhov xaus feem ntau txiav ntawm 90-degree lub kaum sab xis rau cov yeeb nkab khiav rau lub tiaj tus, txawm tias txiav.

Feem ntau, cov kav dej dawb kawg yog siv ua ke nrog cov hlua khi ntawm flanges thiab lub qhov (socket weld fittings) thiab flanges.

Ob qho tib si yuav tsum tau siv cov fillet welding ntawm ib qho los yog ob qho tib si ntawm qhov haum lossis flange thiab ntawm lub hauv paus ntawm qhov haum lossis flange.

Qhov twg siv tau, qhov kawg nkaus yuav muab tso rau feem ntau ⅛ "los ntawm qhov twg cov yeeb nkab so kom tso cai rau thermal expansion thaum vuam.

Qhov no ua rau lawv zoo tagnrho rau cov kav dej me me.

THREADED END (TE) PIPE siv thiab xav txog

Feem ntau siv rau cov kav dej uas muaj qhov loj me ntawm peb-nti lossis me dua, TE cov kav dej tso cai rau lub foob zoo heev.

Feem ntau cov kav dej siv National Pipe Thread (NPT) tus qauv uas piav qhia txog cov xov tapered siv rau ntawm cov yeeb nkab nrog cov feem ntau taper ntsuas 3/4-inch ib ko taw.

Qhov taper no tso cai rau cov xov kom rub nruj thiab tsim kom muaj kev sib khi zoo dua.

Txawm li cas los xij, txuas cov xov ntawm TE yeeb nkab kom zoo yog qhov tseem ceeb kom tsis txhob ua rau cov kav dej puas, fittings, lossis flanges.

Kev sib dhos tsis raug lossis kev tsis sib haum xeeb tuaj yeem ua rau lub plab lossis txeeb.

Thaum unseized, kev puas tsuaj rau cov xov los yog cov yeeb nkab tuaj yeem txo qhov kev tiv thaiv corrosion thiab kev tu cev - ob lub laj thawj nrov rau xaiv cov yeeb nkab steel hlau.

Hmoov zoo, zam cov kev txhawj xeeb no feem ntau yooj yim li kev npaj cov xov ua ntej sib dhos.

Peb pom zoo thiab muag Unasco stainless hlau xov sealing daim kab xev.

Impregnated nrog npib tsib xee hmoov, daim kab xev ua rau saum npoo ntawm txiv neej thiab poj niam xov xaus sib cais thaum tseem lubricating qhov kev sib txuas kom yooj yim sib dhos thiab disassembly.

BEVELLED END (BW) PIPE siv thiab txiav txim siab

Siv nrog buttwelding, BW yeeb nkab fittings feem ntau muaj 37.5-degree bevel.

Cov bevels no feem ntau siv los ntawm fabricators los ntawm tes los yog los ntawm cov txheej txheem automated los xyuas kom meej qhov sib xws.

Qhov no tso cai rau kev sib tw zoo meej nrog BW yeeb nkab fittings thiab flanges thiab vuam yooj yim dua.

GROOVED PIPE siv thiab kev txiav txim siab

Grooved mechanical pob qij txha los yog grooved kawg kav siv ib tug tsim los yog machined groove nyob rau hauv lub kawg ntawm cov yeeb nkab mus zaum ib tug gasket.

Lub tsev nyob ib ncig ntawm lub gasket yog tom qab ntawd nruj kom ruaj ntseg kev sib txuas thiab xyuas kom pom kev sib khi thiab kev ua haujlwm zoo.

Tus tsim tso cai rau kom yooj yim disassembly nrog ib tug txo kev pheej hmoo ntawm puas piping Cheebtsam.

COMMON PIPE END ABBREVIATIONS THIAB STANDARDS

Cov yeeb nkab kawg txuas feem ntau yog siv rau cov txiv mis - feem ntau yog siv cov ntawv luv.

Feem ntau, thawj tsab ntawv qhia txog qhov kawg siv thaum cov ntawv hauv qab no qhia rau koj paub tias qhov twg tiav lawm.
