ASTM A335 P5, sidoo kale loo yaqaan ASME SA335 P5, waa tuubo bir ah oo hooseeya oo aan fiicneyn oo loogu talagalay adeegga heerkulka sare.
P5 waxa ku jira 4.00 ~ 6.00% chromium iyo 0.45 ~ 0.65% molybdenum, oo bixisa awood aad u fiican iyo wax qabad heerkul sare iyo cadaadis. Waxaa si weyn loogu isticmaalaa qalabka sida kuleyliyaha, kulayliyaha sare, iyo kulaylka beddelayaasha.
Magaceeda UNS waa K41545.
Soo saaraha iyo Xaaladda
ASTM A335 P5 tuubooyinka birta waa in lagu sameeyaa habka aan kala go 'lahayn oo waa inay noqdaan kuwo kulul oo la dhammeeyey ama qabow, sida lagu cayimay.
Tuubooyinka kulaylka lagu dhammeeyey waa tuubooyinka birta ah ee aan waxba tarayn ee laga soo saaro biraha iyada oo loo marayo kuleylinta iyo rogrogmada, halka tubooyinka qabow-jiideen ay yihiin tuubooyinka birta ah ee aan waxba tarayn ee soo saara iyaga oo sawiraya tuubooyinka kulul ee heerkulka qolka.
Haddii aad jeclaan lahayd inaad wax badan ka ogaato hababka wax-soo-saarka ee labadan nooc ee tuubooyinka birta, waxaad riixi kartaa"Waa maxay Dhuumaha Birta aan Xumaan lahayn?”Faah faahin dheeri ah.
Daawaynta kulaylka
Tuubooyinka ASTM A335 P5 waa in dib loo kululeeyo si loogu daweeyo kulaylka iyo kulaylka lagu daweeyoAnnealing buuxa ama isothermal or caadiyeyn iyo xanaaqid.
Shuruudaha gaarka ah ayaa lagu muujiyay shaxda hoose:
| Darajo | Nooca daaweynta kulaylka | Hoos u dhigista ama heerkulka |
| ASTM A335 P5 | Anneal buuxa ama isothermal | - |
| caadiyeeyaan oo xanaaqaan | 1250 ℉ [675 ℃] daq |
Hawlgallada ku lug leh kuleylinta tuubooyinka birta ee ka sarreeya heerkulkooda halista ah, sida alxanka, qalooca, iyo foorarsiga kulul, waa in ay raacdaa daawaynta kuleyl habboon.
Hababka tijaabada ee isku dhafka kiimikada iyo sifooyinka farsamada ee tuubooyinka birta ee P5 waa inay u hoggaansamaan qodobada ku habboon ASTM A999.
| Darajo | Halabuurka,% | ||||||
| C | Mn | P | S | Si | Cr | Mo | |
| P5 | 0.15 max | 0.30 ~ 0.60 | 0.025 max | 0.025 max | 0.50 max | 4.00 ~ 6.00 | 0.45 ~ 0.65 |
Guryaha Jilicsan
| Darajo | Xoogga Jilicsan | Xoogga Wax-soo-saarka | Dheeraynta in 2 in. ama 50 mm |
| P5 | 60 ksi [415 MPa] min | 30 ksi [205 MPa] min | 30% min |
Guryaha Adag
Heerka ASTM A335 ma qeexayo wax shuruudo adag oo loogu talagalay tuubooyinka birta ee P5.
Tijaabada fidsan
Tijaabada fidsan waa in la sameeyaa oo laga qaadaa muunad si waafaqsan shuruudaha ku habboon ASTM A999, iyo dhammaadka tuubooyinka la gooyay waxaa loo isticmaali karaa muunado ahaan.
Qallooci Tijaabada
Tuubbada dhexroorkeedu ka sarreeyo NPS 25 oo dhexroorkeeda ilaa dhumucda gidaarka ay tahay 7.0 ama ka yar waa in la mariyaa tijaabada qaloocisa beddelka tijaabada fidsan.
Tijaabada qalooca waa in lagu fooraraa heerkulka qolka ilaa 180° iyada oo aan la dillaacin bannaanka qaybta qaloocan. Dhexroorka laabashadu waa inuu ahaadaa 1 inji [25 mm].
Muuqashada
Dusha sare ee tuubada birta waa inay ahaataa mid siman oo xitaa, oo ka nadiif ah qolof, tolmo, dhabanno, ilmada, ama caarada.
Haddii qoto-dheerida ciladu ka badato 12.5% dhumucda gidaarka magaca ama haddii dhumucda gidaarka hadhay ay ka hoosayso dhumucda ugu yar ee la cayimay, aagga waxa loo qaadanayaa mid cilladaysan.
Marka dhumucda gidaarka soo hartay ay weli ku jirto xadka la cayimay, cilladda waxaa laga yaabaa in lagu saaro shiidi.
Haddii dhumucda gidaarka soo hartay ay ka hooseyso shuruudaha ugu yar, cilladda waa in lagu hagaajiyaa alxanka ama laga saaraa iyadoo la jarayo.
Dulqaadka dhexroorka
Tuubooyinka ay dalbato NPS [DN] ama dhexroorka ka baxsan, kala duwanaanshaha dhexroorka dibadda waa inuusan dhaafin shuruudaha lagu muujiyey shaxda hoose:
| NPS [DN] Nashqadeeye | Kala Duwanaanshaha La Ogolyahay | |
| gudaha | mm | |
| 1/8 ilaa 1 1/2 [6 ilaa 40], inch. | ± 1/64 [0.015] | ±0.40 |
| In ka badan 1 1/2 ilaa 4 [40 ilaa 100], inch. | ± 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 | |
Tuubbada lagu dalbado dhexroorka gudaha, dhexroorka gudaha waa in aanu ka duwanayn wax ka badan 1% dhexroorka gudaha ee la cayimay.
Dulqaadyada Dhumucda Darbiga
Marka lagu daro xaddidaadda qarsoon ee dhumucda gidaarka ee tuubada ay soo rogtay xaddidaadda miisaanka ASTM A999, dhumucda gidaarka ee tuubada meel kasta waa inay ku jirtaa dulqaadka lagu qeexay shaxda hoose:
| NPS [DN] Nashqadeeye | Dulqaadasho, % qaab cayiman |
| 1/8 ilaa 2 1/2 [6 ilaa 65] oo ay ku jiraan. dhammaan saamiga 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 gidaarka ee cayiman; D = Dhexroor ka baxsan oo cayiman. | |
