API 5L X52 Short Pipe Nrog Groove Ends
API 5L X52 Short Pipe nrog Grooved Endsyog ib lub raj xa hluav taws xob ua ntej (feem ntau hu ua "spool" lossis "nipple") ua los ntawm Qib X52 kab yeeb nkab.
Khoom siv:X52 (los yog L360) yog nruab nrab - lub zog steel nrog qhov tsawg kawg nkaus lub zog ntawm52,200 psi (360 MPa).
Grooved Ends:Es tsis txhob beveled rau welding, qhov kawg feature ib ncig groove (txawm dov los yog txiav) raws li cov qauv zoo liANSI/AWWA C606.
Lub hom phiaj:Cov kav dej no yog tsim los siv nrogmechanical grooved couplings(eg, Victaulic systems). Qhov no tso cai rau kev txhim kho sai, kev co dampening, thiab muaj peev xwm ua kom haum rau thermal expansion yam tsis tas yuav tsum tau ua haujlwm kub (vuam).

Kev ntsuas siab
Lub siab ntsuas ntawm ib tug grooved luv yeeb nkab yog txiav txim los ntawm lubLub Sijhawm Yeeb Nkab (Wall Thickness)thiab covHom kev sib txuassiv.
Sch 40 Pipe (X52):Feem ntau tuaj yeem tswj cov kev ua haujlwm siab los ntawm300 psi rau 1000 psinyob ntawm lub coupling hom thiab txoj kab uas hla.
Safety Factor:Cov txheej txheem grooved feem ntau ua raws li 3: 1 kev nyab xeeb raws li kev sib txuas ntawm qhov ntsuas siab.
Nta & Cov txiaj ntsig
Siab zog - rau - Qhov hnyav piv:X52 muab kev kub siab ua haujlwm siab dua li qib B yeeb nkab, tso cai rau cov phab ntsa nyias nyias hauv qee kis.
Flexible Installation:Grooved kawg tso cai rau ± 1℃rau ± 3℃ntawm angular deflection, ua rau lawv zoo meej rau qhov tsis sib xws lossis thaj chaw seismic.
Kev kho qis:Mechanical pob qij txha yooj yim dua rau disassemble rau cov yeeb nkab tu lossis tshuaj xyuas piv rau cov pob qij txha welded.
Kev nyab xeeb:Tsis muaj -kev teeb tsa hluav taws (tsis muaj vuam) yog qhov zoo tshaj plaws rau kev rov ua dua tshiab hauv cov khoom siv roj / roj uas twb muaj lawm.
Daim ntawv thov
Roj & Gas Sib Sau Kab:Rau txuas cov twj tso kua mis thiab manifolds.
Industrial Fire Protection:Siab - cov kab tseem ceeb rau cov tshuaj txau.
HVAC Systems:Loj loj chilled / dej kub ncig hauv cov tsev lag luam.
Mining:Slurry thiab tailings thauj kab.
Kev kho dej khib nyiab:Tshuaj thiab dej hloov kab uas yuav tsum tau modularity.
Hom kev tsim khoom
Cov "cov yeeb nkab luv" pib raws li tus qauv API 5L X52 kab yeeb nkab uas tsim los ntawm:
Seamless (SMLS):Qhov zoo tshaj plaws rau kev siv siab -siab qhov uas tsis muaj vuam seam yog nyiam.
Electric Resistance Welded (ERW):Feem ntau thiab raug nqi - hom zoo rau X52 qib nyob rau hauv nruab nrab -ntau txoj kab uas hla.
SSAW / SSAW:Siv rau txoj kab uas hla loj heev luv luv (dhau 24 ").
Txoj kev Grooving:
Roll Grooving:Txias- txheej txheem tsim uas tshem cov hlau los ua ib qho zawj. Zoo tagnrho rau cov qauv phab ntsa thiab nyias - cov kav dej (Sch 10/40).
Txiav Grooving:Tshem tawm cov hlau los ntawm cov yeeb nkab phab ntsa. Feem ntau yog siv rau hnyav- cov kav dej phab ntsa (Sch 80+) kom tswj tau qhov dej ntws sab hauv.
Kev Xeem Xeem
Txhawm rau kom muaj kev nyab xeeb nyob rau hauv siab - cov roj siab, roj, lossis cov kav dej, cov kav dej no tau txais:
Kev Ntsuas Hydrostatic:100% ntawm cov kav dej raug kuaj xyuas kom ntseeg tau tias lub cev thiab vuam seam yog leak- pov thawj.
NDT (Tsis yog -Kev kuaj kev puas tsuaj):Ultrasonic lossis Radiographic kuaj (yuav tsum tau rau PSL2).
Mechanical Tests:Tensile, Flattening, thiab Khoov xeem.
Groove Dimension Inspection:Kev tshuaj xyuas tseem ceeb siv "Go/No-Go" gauges los txheeb xyuas txoj kab uas hla (C), qhov dav (A), thiab qhov tob kom paub tseeb tias qhov xau{1}}dawb foob nrog cov txuas txuas.

FAQ
Qhov txawv ntawm API 5L X52 PSL1 thiab PSL2 yog dab tsi?
Qhov txawv tseem ceeb yog qhov ntawdPSL1yog tus qauv zoo qib rau kev siv dav dav, thaumPSL2yog qhov siab dua - qib qhia tshwj xeeb rau ib puag ncig tseem ceeb (xws li siab -siab lossis txias- huab cua kav).
Nov yog plaub qhov sib txawv tseem ceeb:
Toughness (Kev Ntsuas Kev Ntsuas):PSL2 yuav tsum tau uaCharpy V-Ntch (Impact) kuajkom ntseeg tau tias cov yeeb nkab yuav tsis tawg nyob rau hauv kev ntxhov siab lossis txias txias. PSL1 tsis xav tau qhov no.
Tshuaj muaj pes tsawg leeg:PSL2 muaj kev txwv nruj dua ntawm Carbon thiab Sulfur cov ntsiab lus thiab suav nrog aCarbon sib npaug (CE)cap los xyuas kom meej weldability zoo.
Mechanical Strength:PSL2 muaj ibsiab kawgyield lub zog txwv kom ntseeg tau tias cov yeeb nkab tseem ductile (tsis dhau nkig), qhov PSL1 tsuas yog muaj qhov tsawg kawg nkaus.
Traceability & Inspection:PSL2 yuav tsum muaj tag nrho traceability thiab nruj dua Tsis yog-Kev Ntsuas Kev Puas Tsuaj (NDT) piv rau PSL1.
Cov grooves ua raws li tus qauv twg?
A:Txawm hais tias cov khoom siv yeeb nkab ua rawsAPI 5L X52, qhov zawj qhov ntev feem ntau ua rawsANSI/AWWA C606los yog cov chaw tsim khoom tus qauv (xws li Victaulic specifications) los xyuas kom meej compatibility nrog cov txheej txheem mechanical couplings.
Koj puas muab "Roll Grooving" lossis "Cut Grooving"?
A:Peb muab ob qho tib si.Yob Groovingraug pom zoo rau cov qauv thiab nyias- cov kav dej phab ntsa (Sch 10/40) vim nws khaws cov khoom siv ruaj khov.Txiav Groovingfeem ntau yog siv rau hnyav- cov kav dej hauv phab ntsa (Sch 80 thiab siab dua) qhov twg yuav tsum muaj qhov sib luag sab hauv.
