Chiyero cheASTM A106 uye ASTM A53:
Kutsanangurwa kweASTM A53 kunovhara mhando dzesimbi dzekugadzira pombi dzisina musono uye dzakasungwa, zvinhu mucarbon simbi, simbi nhema.Pamusoro pechisikigo, dema, uye inopisa-yakanyikwa galvanized, zinc yakavharidzirwa simbi pombi.Madhayamita anotangira paNPS 1⁄8 kusvika kuNPS 26 (10.3mm kusvika 660mm), ukobvu hwemadziro nezita.
ASTM A106 yakajairwa yakatarwa inovhara iyocarbon seamless simbi pombi, yakanyorera mabasa ekupisa kwepamusoro.
Mhando dzakasiyana uye mamakisi kune ese akajairwa:
Kune ASTM A53 kune ERW uye isina musono pombi dzesimbi Type F, E, S inovhara Giredhi A uye B.
A53 Type F, choto butt yakasungwa, inoenderera weld Giredhi A
A53 Type E, Magetsi kuramba akaiswa welded (ERW), muGiredhi A uye Giredhi B.
A53 Type S, Seamless simbi pombi, muGiredhi A uye Giredhi B.
Kana simbi yakasvibirira yemagiredhi akasiyana ichiri kuenderera mberi ichikandira, shanduko yezvinhu ichaonekwa.Uye mugadziri anofanira kubvisa shanduko yezvinhu nematanho anogona kuparadzanisa mamakisi zvakanaka.
Kana ASTM A53 Giredhi B muERW (electric resistance welded) pombi, weld musono uchaitwa kupisa kwekupisa ne1000°F [540°C] shoma.Nenzira iyi hapana untempered martensite inoramba iripo.
Kana iyo ASTM A53 B pombi mukutonhora yakawedzera, ipapo kuwedzera hakufanirwe kudarika 1.5% yeOD inodiwa.
YeASTM A106 simbi pombi, kugadzira Type chete mune isina musono, maitiro ekupisa akakungurutswa uye kutonhora kunokweva.Giredhi muA, B neC.
ASTM A106 Giredhi A: Maximum Carbon element 0.25%, Mn 0.27-0.93%.Minimum tensile simba 48000 Psi kana 330 Mpa, goho simba 30000 Psi kana 205 Mpa.
A106 Giredhi B: Maximum C pazasi 0.30%, Mn 0.29-1.06%.Minimum tensile simba 60000 Psi kana 415 Mpa, goho simba 35000 Psi kana 240 Mpa.
Giredhi C: Maximum C 0.35%, Mn 0.29-1.06%.Minimum tensile simba 70000 Psi kana 485 Mpa, goho simba 40000 Psi kana 275 Mpa.
Zvakasiyana neASTM A53 GR.B mapaipi esimbi asina musono,ASTM A106 GR.B mapaipi esimbi asina musonoine Si min 0.1%, iyo A53 B ine 0, saka A106 B ine nani kupisa kupisa kupfuura A53 B, sezvo Si inovandudza kupisa kupisa.
Nzvimbo dzekushandisa dzese dziri mbiri:
Mapombi ese ari maviri akanyorera ma mechanic uye pressure system, kutakura chiutsi, mvura, gasi, nezvimwe.
ASTM A53 pombi application:
1. Kuvaka, kutakura pasi pevhu, kutorwa kwemvura yepasi paunenge uchivaka, kutakura kwemvura yemvura nezvimwewo.
2. Kutakura seti, michina yezvikamu zvekugadzirisa.
3. Kushandiswa kweMagetsi: Kutumira gasi, mvura yekugadzira mvura yepombi yemvura.
4. Mhepo simba rekudyara anti-static chubhu nezvimwe.
5. Mapaipi aida zinc yakavharwa.
ASTM A106 pombi application:
Kunyanya kune yakakwira tembiricha masevhisi anosvika 750 ° F, uye inogona kutsiva ASTM A53 pombi mune mazhinji emakesi.Mune dzimwe nyika kuUnited States, kazhinji ASTM A53 ndeye welded pombi nepo ASTM A106 ndeyemapombi esimbi asina musono.Uye kana mutengi akakumbira ASTM A53 ivo vanozopawo ASTM A106.MuChina, mugadziri achapa pombi inoenderana nematatu matatu ASTM A53 GR.B/ASTM A106 GR.B/API 5L GR.B mapaipi esimbi asina musono.
