ASTM A53 Hom E - Hluav taws xob tsis kam welded yeeb nkab.
Hom E Garde A thiab Garde B cov kav dej yog tsim los ntawm cov kab txuas txuas ntxiv, thiab cov kab txuas txuas ntev yog welded los ntawm cov hluav taws xob los ntawm hluav taws xob tiv thaiv ntawm cov yeeb nkab qhov kawg. Ib txheej ntawm rollers kuj tau ua haujlwm nyob rau hauv qhov kev ua haujlwm no los sib sau ua ke rhuab kawg. Tom qab vuam, lub vuam seam ntawm Qib cov kav dej yog cua sov- kho kom tsawg kawg yog 540℃.
ASTM A53 Hom S - Seamless Yeeb Nkab
Cov txheej txheem extrusion yog siv los tsim hom S kav.
Cov hlau nyoos uas xav tau los ua cov kav dej yog tsim los ntawm kev qhib -heart furnace, lub cub hluav taws xob, lossis cov txheej txheem - pa oxygen.
Kev thov thiab kev siv ntawm ASTM A53 PIPING
ASTM A53 Pipes rau Roj & Roj
ASTM A53 cov kav dej tau siv rau ntau yam kev siv, suav nrog kev ua khoom lag luam, kev siv dej hiav txwv, thiab kev thauj mus los ntawm cov roj thiab cov pa roj thiab kua. Peb cov neeg siv khoom feem ntau thov los tiv thaiv- txheej corrosive rau cov kav dej siv los nqa roj, roj av, thiab propane, thiab peb zoo siab los muab.
ASTM A53 cov kav dej, uas feem ntau yog tsim los ntawm cov pa roj carbon steel lossis cov hlau tsis tshua muaj hlau, tsis tshua muaj nqi los tsim dua tubing feem ntau. Txhawm rau txiav txim siab ntau npaum li cas cov khoom tuaj yeem ntws los ntawm cov yeeb nkab, txoj kab uas hla sab hauv ntawm cov yeeb nkab yog qhov ntsuas tseem ceeb tshaj plaws. Kev ntsuas siab, lub zog tawm los, thiab kev sib tw yog txhua yam tseem ceeb uas yuav tsum xav txog.
ASTM A53 Pipes rau Cov Hlau Hlau
Muaj ntau txoj kab uas hla thiab qib muaj nyob, tso cai rau ASTM A53 yeeb nkab siv rau ntau yam kev siv cov txheej txheem sib txawv nrog rau ntau yam kev ua haujlwm ntau yam. Kem, bollards, kos npe ncej, kev txhawb nqa, thiab piling tsuas yog ob peb ntawm cov ntawv thov rau cov yeeb nkab uas muaj ntau yam.
ASTM A53 Pipes rau Hlau Conduit
ASTM A53 metallic conduit kav yog cov hlau ruaj khov-raws li cov ntaub ntawv uas siv los ua ib tus neeg siv hluav taws xob xaim hluav taws xob thoob plaws hauv lub tsev lossis cov qauv thaum tiv thaiv cov xov hlau los ntawm kev cuam tshuam, noo noo, thiab tshuaj vapors. Conduit kav thiab hluav taws xob hlau tubing (EMT) kuj hu ua EMT.
Conduit kav yog categorized raws li cov thickness ntawm cov phab ntsa, mechanical stiffness ntawm cov pob qij txha, thiab cov khoom siv. Cov kav dej yog ua los ntawm galvanized steel hlab nrog phab ntsa tuab txaus los pab kom lawv tau threaded. Galvanized rigid conduit pipes (GRC) yog ib yam ntawm cov kav dej tsis zoo uas yog threaded. Intermediate hlau conduit yeeb nkab (IMC) yog ib qho sib dua - hnyav, nyias txawv ntawm cov hlau tsis sib xws (RMC).
ASTM A53 raj yog kub-dipped galvanized thiab ces tshuab ziab kom tsis txhob zinc buildup nyob rau hauv lub raj. Nyob rau sab nraud, lub lacquer ntshiab yog siv los muab lub neej txee ntev. Qhov zoo tshaj plaws ductility ntawm cov kav dej tso cai rau kev khoov yooj yim, threading, thiab txiav ua haujlwm.
ASTM A53 Pipes rau Conveyor Cov Menyuam
ASTM A53 conveyor cov menyuam cov kav dej tuaj yeem ua tshuab thiab ua tiav rau hauv cov menyuam conveyor. Conveyor roller pipes yog cov khoom siv ntawm txoj siv conveyor uas siv los thauj cov khoom lossis cov khoom xoob xoob xws li thee, xuab zeb, lossis hlau ore. Conveyor roller pipes yog ib qho tseem ceeb ntawm cov kab ke no thiab yuav tsum tau ua kom muaj kev thauj mus los.
Lub conveyor txoj siv thauj khoom thauj khoom thaum nws ncig ntawm lub pulleys thiab cov menyuam cov kav dej. Conveyor pulleys yog lub luag haujlwm rau kev tsav tsheb txoj siv, tswj kev nruj ntawm nws, thiab coj nws mus rau qhov xav tau. Xav paub ntau ntxiv hais txog lub hom phiaj thiab kev ua haujlwm ntawm conveyor pulleys tuaj yeem pom hauv peb cov ntawv tshaj tawm blog ntawm cov ncauj lus. Conveyor roller pipes yog lub luag hauj lwm rau kev thauj cov conveyor siv los ntawm ib lub nruas mus rau lwm qhov. Lawv tsuas yog siv los muab kev txhawb nqa rau txoj siv.

TEST & INSPECTION thaum lub sij hawm ASTM A53 PIPE PRODUCTION
- Tshuaj ntsuam xyuas- Tus naj npawb ntawm kev xeem: 2 daim txhua qhov ntau ntawm 500 lossis 2 daim rau ib lub tshav kub. (Yog tias ob lub yeeb nkab tsis ua haujlwm, yuav tsum tau sim ob daim ntxiv ntawm tib lub batch.)
- Tensile Test- Qhov kev sim no yog ua los ntsuas cov khoom siv ntawm cov yeeb nkab. Nyob rau hauv cov ntaub ntawv ntawm welded yeeb nkab, lub weld lub zog yuav tsum tsis txhob tsawg tshaj li cov yeeb nkab lub cev lub zog.
- Bending Test- Ntawm cov yeeb nkab diameters NPS 2 thiab tsawg dua, kev sim khoov yog ua los txiav txim siab qhov ductility ntawm cov yeeb nkab. Kev ntsuas khoov tuaj yeem yog 90 degrees lossis 180 degrees, nyob ntawm qhov xwm txheej.
- Flattening Test- Rau ductility, cov yeeb nkab loj dua li NPS 2 yog flattening kuaj. Nyob rau hauv txoj kab nrog ASTM A53, cov qauv yeeb nkab yog hlais thiab flattened ntawm ob qhov chaw tiaj tus.
- Hydro-Test- Qhov no yog ib qho kev sim uas tau ua nyob rau txhua qhov ntev ntawm cov yeeb nkab los txiav txim seb puas muaj qhov xau. Lub siab yuav tsum tau tswj kom tsawg li 5 vib nas this.
- Weld Seam Ultrasonic lossis Electromagnetic Test- Qhov no tsis yog -kev ntsuas kev puas tsuaj yog ua nyob rau hauv tag nrho qhov ntev ntawm lub vuam los xyuas qhov kev ncaj ncees ntawm qhov vuam.
