"Simbi yesimbi yemapaipi HTASTM A335 GR P22- SCH 80. ASME B36.10 ZVINHU ZVISINA KUGADZIRA (ZVINHU ZVAKAWANDA: M)" imhando yezviratidzo zvehunyanzvi zvinotsanangura mapaipi esimbi akagadzirwa. Ngatizviongororei imwe neimwe:

Simbi yeAlloy yemapaipi HT:
"PIPE" zvinoreva pombi, uye "ALLOY STEEL" zvinoreva simbi yesimbi. Simbi yesimbi ine chimwe kana zvimwe zvinhu zvekubatanidza (zvakaita sechromium, molybdenum, tungsten, nezvimwewo) uye ine hunhu hwakanaka hwakadai sekudzivirira kupisa kwakanyanya, kudzivirira ngura uye kusimba.

"HT" inowanzo reva zvinodiwa pakupisa kwakanyanya, zvichiratidza kuti simbi iyi yepombi yakakodzera nzvimbo dzinopisa zvakanyanya.

ASTM A335 GR P22:
Iyi itsananguro yemhando uye giredhi rezvinhu zvepombi.

ASTM A335ndiyo mwero wakagadzirwa neAmerican Society for Testing and Materials (ASTM) wemapaipi esimbi asina musono, kunyanya munzvimbo dzinopisa zvakanyanya uye dzine kumanikidzwa kwakanyanya.
GR P22 ndiyo mhando chaiyo yezvinhu pasi pechiyero ichi, apo "P22" inoratidza kuumbwa kwemakemikari uye zvinodiwa pakushanda kwechinhu chepombi. Simbi yeP22 alloy inowanzo kuve ne chromium (Cr) uye molybdenum (Mo), ine simba rakanaka pakupisa kwepamusoro uye inodzivirira ngura, uye yakakodzera munzvimbo dzinopisa zvakanyanya.
SCH 80:
Izvi zvinoreva giredhi reukobvu hwemadziro epombi, uye "SCH" ipfupiso ye "Schedule".

SCH 80 zvinoreva kuti ukobvu hwemadziro epombi hwakakora uye hunogona kumira kumanikidzwa kwakanyanya kwemukati. Kune mapaipi eSCH 80, ukobvu hwemadziro ayo hwakakura pakati pemapaipi ane dhayamita imwe chete, izvo zvinogona kuwedzera kugona kwayo kudzvanywa uye kuramba kukanganiswa.
ASME B36.10:
Uyu mwero wakagadzirwa neAmerican Society of Mechanical Engineers (ASME) unotsanangura saizi, chimiro, kushivirira, huremu nezvimwe zvinodiwa nemapaipi esimbi. B36.10 inonyanya kunanga dhayamita yekunze, ukobvu hwemadziro nezvimwe zviyero zvemapaipi asina musono esimbi yekabhoni nesimbi ye alloy uye mapaipi akasungirirwa kuti ive nechokwadi chekuenzana uye kugadzikana kwezvigadzirwa zvepaipi.

MHEDZISO DZAKAVANZIKA:
"Magumo Asina Kutsetseka" zvinoreva mapaipi asina magumo ekugadzirisa kana ekubatanidza, kazhinji ane nzvimbo dzakachekwa dzakatsetseka. Zvichienzaniswa nemapaipi ane tambo kana flange, mapaipi ekupedzisira asina kutsetseka anowanzo shandiswa mukushandiswa uko kubatanidza kwakabatana kunodiwa.

CHIKAMU CHEHuwandu: M:
Izvi zvinoratidza kuti chikamu chekuyera chigadzirwa ichi i "meter", kureva kuti, huwandu hwepombi hunoyerwa mumamita, kwete zvidimbu kana zvimwe zvikamu.

Pombi inotsanangurwa mutsananguro iyi ipombi yesimbi ine tembiricha yepamusoro inosangana neASTM A335 GR P22 standard, ine ukobvu hwemadziro hweSCH 80 uye inosangana nechiyero cheASME B36.10 size. Migumo yepombi haina kupfava (hapana tambo kana flanges), kureba kwayo kunoyerwa nemamita, uye yakakodzera masisitimu emapaipi munzvimbo dzinopisa zvakanyanya, kumanikidzwa uye dzinopisa.
