ASTM A335 P5, oo sidoo kale loo yaqaan ASME SA335 P5, waa tuubo bir ah oo aan lahayn daawaha oo loogu talagalay adeegga heerkulka sare.
P5 wuxuu ka kooban yahay 4.00 ~ 6.00% chromium iyo 0.45 ~ 0.65% molybdenum, taasoo bixisa xoog iyo waxqabad aad u fiican marka heerkulku sarreeyo iyo cadaadiska. Waxaa si weyn loogu isticmaalaa qalabka sida kuleyliyeyaasha, kuleyliyeyaasha sare, iyo beddelayaasha kulaylka.
Magaca UNS waa K41545.
Soo-saaraha iyo Xaaladda
Tuubooyinka birta ah ee ASTM A335 P5 waa in lagu sameeyaa habka aan kala go 'lahayn waana in lagu sameeyaa kuleyl ama qabow, sida ku cad.
Tuubooyinka kulul ee la dhammeeyay waa tuubooyin bir ah oo aan kala go 'lahayn oo laga sameeyay billets iyada oo loo marayo hababka kuleylinta iyo rogidda, halka tuubooyinka qabowga lagu shubo ay yihiin tuubooyin bir ah oo aan kala go' lahayn oo laga soo saaro tuubooyin kulul oo la dhammeeyay heerkulka qolka.
Haddii aad jeclaan lahayd inaad wax badan ka barato hababka wax soo saarka ee labada nooc ee tuubooyinka birta ah ee aan kala go 'lahayn, waxaad gujin kartaa"Waa maxay tuubo bir ah oo aan tolnayn?"wixii faahfaahin dheeraad ah.
Daaweynta Kulaylka
Tuubooyinka ASTM A335 P5 waa in dib loo kululeeyaa si loogu daweeyo kulaylka iyo kulaylka iyadoo la adeegsanayodaadinta buuxda ama midda isothermal-ka ah or caadiyeynta iyo hagaajinta.
Shuruudaha gaarka ah waxaa lagu muujiyay jadwalka hoose:
| Fasal | Nooca daaweynta kulaylka | Qaboojinta ama Heerkulka Hoosaadka ah |
| ASTM A335 P5 | annaalka buuxa ama isothermal-ka ah | — |
| caadi u noqo oo dabeecad samee | 1250 ℉ [675 ℃] daqiiqo |
Hawlgallada ku lug leh kululaynta tuubooyinka birta ah heerkulkooda muhiimka ah, sida alxanka, flanging, iyo leexashada kulul, waa in lagu daraa daaweyn ku habboon.
Hababka tijaabada ee halabuurka kiimikada iyo sifooyinka farsamada ee tuubooyinka birta ah ee P5 waa inay u hoggaansamaan qodobbada khuseeya ee ASTM A999.
| Fasal | Halabuurka, % | ||||||

Astaamaha Adkaanta
Heerka ASTM A335 ma qeexayo wax shuruudo adag ah oo loogu talagalay tuubooyinka birta ah ee P5.
Imtixaanka Fiditaanka
Tijaabada fidsanaan waa in la sameeyaa oo la muunadeeyaa iyadoo la raacayo shuruudaha khuseeya ee ASTM A999, dhammaadka tuubooyinka la jarayna waxaa loo isticmaali karaa muunad ahaan.
Imtixaanka Laabista
Tuubada dhexroorkeedu ka badan yahay NPS 25 oo dhexroorkeedu yahay saamiga dhumucda derbiga 7.0 ama ka yar waa in lagu sameeyaa tijaabada qallooca halkii laga isticmaali lahaa tijaabada siman.
Shaybaarada tijaabada qallooca waa in lagu qaloociyaa heerkulka qolka ilaa 180° iyada oo aan dildilaac laga gelin dibadda qaybta qalloocan. Dhexroorka gudaha ee qallooca waa inuu ahaadaa 1 inji [25 mm].
Muuqaalka
Dusha sare ee tuubada birta ah waa inay ahaataa mid siman oo siman, oo aan lahayn qolof, tolmo, dhabooyin, jeexdin, ama jajabyo.
Haddii qoto dheer ee cillad kasta ay ka badan tahay 12.5% dhumucda derbiga magacaaban ama haddii dhumucda derbiga ee hartay ay ka hooseyso dhumucda ugu yar ee la cayimay, aagga waxaa loo tixgelin doonaa mid cilladaysan.
Marka dhumucda derbiga ee hartay ay weli ku jirto xadka la cayimay, cilladda waxaa laga saari karaa iyadoo la shiido.
Haddii dhumucda derbiga ee hartay ay ka hooseyso shuruudaha ugu yar, cilladda waa in lagu hagaajiyaa alxanka ama laga saaraa jarista.
Dulqaadka Dhexroorka
Tuubooyinka ay dalbatay NPS [DN] ama dhexroorka dibadda, kala duwanaanshaha dhexroorka dibadda waa inaysan dhaafin shuruudaha ku cad jadwalka hoose:
| NPS [DN] Naqshadeeye | Kala Duwanaanta La Ogol Yahay | |
| gudaha. | mm | |
| 1/8 ilaa 1 1/2 [6 ilaa 40], inji. | ±1/64 [0.015] | ±0.40 |
| In ka badan 1 1/2 ilaa 4 [40 ilaa 100], inji. | ±1/32 [0.031] | ±0.79 |
| In ka badan 4 ilaa 8 [100 ilaa 200], inji. | -1/32 - +1/16 [-0.031 - +0.062] | -0.79 - +1.59 |
| In ka badan 8 ilaa 12 [200 ilaa 300], inji. | -1/32 - +3/32 [-0.031 - 0.093] | -0.79 - +2.38 |
| In ka badan 12 [300] | ±1% dhexroorka dibadda ee la cayimay | |
Tuubada loo dalbaday dhexroor gudaha ah, dhexroorka gudaha waa inaanu ka badnayn 1% dhexroorka gudaha ee la cayimay.
Dulqaadka Dhumucda Darbiga
Marka laga soo tago xaddidaadda aan tooska ahayn ee dhumucda derbiga ee tuubooyinka oo ay ku soo rogtay xaddidaadda miisaanka ee ASTM A999, dhumucda derbiga ee tuubooyinka wakhti kasta waa inay ku jirtaa dulqaadka lagu qeexay jadwalka hoose:
| NPS [DN] Naqshadeeye | Dulqaad, % foomka la cayimay |
| 1/8 ilaa 2 1/2 [6 ilaa 65] oo ay ku jiraan dhammaan saamiyada t/D | -12.5 - +20.0 |
| Ka sarreeya 2 1/2 [65], t/D ≤ 5% | -12.5 - +22.5 |
| Ka sarreeya 2 1/2, t/D ＞ 5% | -12.5 - +15.0 |
| t = Dhumucda Darbiga ee la cayimay; D = Dhexroorka Dibadda ee la cayimay. | |
