ASTM A335 P5, inozivikanwawo se ASME SA335 P5, isimbi yakadzika-alloy isina musono pombi yakagadzirirwa basa repamusoro-tembiricha.
P5 ine 4.00 ~ 6.00 % chromium uye 0.45 ~ 0.65% molybdenum, inopa simba rakanakisa uye kushanda pasi petembiricha yakakwira nedzvinyiriro. Inoshandiswa zvakanyanya mumidziyo yakadai semaboilers, superheaters, uye zvinopisa zvinopisa.
Yayo UNS zita iK41545.
Mugadziri uye Mamiriro
ASTM A335 P5 mapombi esimbi achagadzirwa nemaitiro asina musono uye angave achipisa apera kana kutonhora anodhonzwa, sekutsanangurwa kwazvino.
Mapombi anopera-kupisa mapombi esimbi asina musono anogadzirwa kubva kumabhiriji kuburikidza nekudziya uye kutenderedza maitiro, nepo pombi dzinodhonzwa nechando mapaipi esimbi asina musono anogadzirwa nekudhirowa mapaipi anopisa-anopera patembiricha yekamuri.
Kana iwe uchida kudzidza zvakawanda nezve maitiro ekugadzira emhando mbiri idzi dzesimbi isina musono pombi, unogona kudzvanya“Chii chinonzi Seamless Steel Pipe?”kuti uwane mamwe mashoko.
Kupisa Kurapa
ASTM A335 P5 mapaipi anozodziiswa patsva kurapwa kwekupisa uye kupisa kunobatwa nayokuzara kana isothermal annealing or normalizing uye kupisa.
Izvo zvinodiwa chaizvo zvinoratidzwa mutafura iri pazasi:
| Giredhi | Kupisa kubata mhando | Subcritical Annealing kana Temperature |
| ASTM A335 P5 | yakazara kana isothermal anneal | - |

Mashandiro anosanganisira kudziyisa pombi dzesimbi pamusoro petembiricha yadzo yakaoma, senge welding, flanging, uye kukotama kunopisa, zvinofanirwa kuteverwa nekurapa kwakakodzera kwekupisa.
Nzira dzekuyedza dzekugadzirwa kwemakemikari uye mekiniki zvivakwa zveP5 simbi pombi dzinoenderana nezvinodiwa zveASTM A999.

Hardness Properties
Iyo ASTM A335 yakajairwa haitsanangure chero hurema hunodiwa kune P5 simbi pombi.
Flattening Test
Bvunzo rekuti flattening richaitwa uye kuenzanisirwa zvinoenderana nezvinodiwa zveASTM A999, uye migumo yepombi yakadzvanywa inogona kushandiswa semuenzaniso.
Bend Test
Yepombi ine dhayamita inodarika NPS 25 uye iyo dhayamita kusvika kumadziro ukobvu reshiyo iri 7.0 kana zvishoma ichaiswa pakuyedzwa kwekubhenda pachinzvimbo cheyedzo yekubata kumeso.
Iyo bend test samples ichave yakakotama pakamuri tembiricha kuburikidza ne180 ° pasina kuputika kunze kwechikamu chakabhenda. Iyo yemukati dhayamita yekubhenda ichave 1 mukati. [25 mm].
Chitarisiko
Pamusoro pepombi yesimbi ichave yakatsetseka uye yakatsetseka, isina makwapa, seam, makumbo, misodzi, kana zvidimbu.
Kana hudzamu hwehumwe hurema hwakapfuura 12.5% yezita remadziro ukobvu kana kana iyo yakasara madziro ukobvu iri pasi pehudiki hwakatarwa ukobvu, nzvimbo yacho ichaonekwa isina kukwana.
Kana iyo yakasara madziro emadziro ichiri mukati memiganhu yakatarwa, kukanganisa kunogona kubviswa nekukuya.
Kana iyo yakasara madziro emadziro iri pazasi pezvishoma zvinodiwa, chirema chichagadziriswa ne welding kana kubviswa nekucheka.
Diameter Tolerance
Pamapombi akarairwa neNPS [DN] kana dhayamita rekunze, kusiyana kwedhayamita yekunze hakufanire kudarika zvinodiwa patafura iri pazasi:
