Simbi Pipe Dimension 3 Mavara:
Tsananguro yakazara yesimbi pombi dimension inosanganisira yekunze dhayamita (OD), ukobvu hwemadziro (WT), hurefu hwepombi (Kazhinji 20 ft 6 mita, kana 40 ft 12 metres).

Kuburikidza nemabhii aya taigona kuverenga huremu hwepombi, kuti pombi inotsikirira yakadii, uye mutengo parutsoka kana mita.
Naizvozvo, ndosaka tichifanira kugara tichiziva saizi chaiyo yepombi.

Simbi Pipe Dimensions Chati

Pipe Schedule Chati unit mu mm sepazasi, tarisa pano yePipe Rondedzero Chati mu inch.

Dimension mipimo yesimbi pombi
Pane zviyero zvakasiyana kutsanangura simbi pombi saizi, OD uye madziro ukobvu. Zvikuru zviri ASME B 36.10, ASME B 36.19.

Hunoenderana mwero yakatarwa ASME B 36.10M uye B 36.19M
Ose ASME B36.10 uye B36.19 ndiwo akajairwa zvirevo zvehukuru hwepombi yesimbi uye zvishongedzo.

ASME B36.10M
Iyo chiyero inovhara kumira kwesimbi pombi zviyero uye saizi. Mapombi aya anosanganisira asina musono kana welded mhando, uye anoshandiswa mukupisa kana kuderera tembiricha uye kumanikidza.
Iyo pombi inosiyaniswa nechubhu (Pipe vs Tube), pano pombi ndeyekunyanya kune pombi masisitimu, zvinwiwa (Mafuta negesi, mvura, slurry) kutapurirana. Shandisa mwero weASME B 36.10M.
Mune chiyero ichi, pombi Outer Dimita idiki pane 12.75 mu (NPS 12, DN 300), pombi madhayamita chaiwo akakura kupfuura NPS (Nominal Pipe Size) kana DN (Nominal Diameter).

Paruoko, nokuda kwesimbi chubhu dimensions, chaiwo kunze dhayamita zvakafanana nepombi nhamba yose saizi.

Chii chinonzi Steel Pipe Dimensions Schedule?
Simbi pombi hurongwa inzira inoratidza inomiririrwa neASME B 36.10, uye inoshandiswawo mune mamwe akawanda miyero, yakanyorwa ne “Sch”. Sch ndiyo chidimbu chechirongwa, chinowanzoitika muAmerican steel pipe standard, inova prefix yenhamba dzakatevedzana. Semuenzaniso, Sch 80, 80 inhamba yepombi kubva chati/tafura ASME B 36.10.

“Sezvo pombi yesimbi inoshandiswa zvikuru kutakura zvinwiwa zviri pasi pekumanikidzwa, saka dhayamita yadzo yemukati ndiyo saizi yavo yakaoma. Iyi saizi yakakosha inotorwa sezita rezita (NB). Naizvozvo, kana pombi yesimbi ikatakura zvinwiwa zvine simba, zvakakosha kuti pombi ive nesimba rakakwana uye ukobvu hwakakwana hwemadziro. Saka ukobvu hwemadziro hunotsanangurwa muZvirongwa, zvinoreva chirongwa chepombi, chakapfupikiswa seSCH. Pano ASME ndiyo yakapihwa mwero uye tsananguro yehurongwa hwepombi. "

Iyo pipe schedule formula:
Sch.=P/[ó]t×1000
P ndiyo Yakagadzirirwa kudzvinyirirwa, zvikamu muMPa;
[ó] t inobvumirwa kushushikana kwezvinhu pasi petembiricha yekugadzira, Units muMPa.

Chii chinorevei SCH kune simbi pombi zviyero?
Sekutsanangura simbi pombi parameter, tinowanzo shandisa pombi purogiramu, Ndiyo nzira inomiririra pombi rusvingo ukobvu nenhamba. Kuronga kwepombi ( sch. ) haisi kukora kwemadziro, asi kutevedzana kwemadziro. Different pipe schedule inoreva kusiyana kwemadziro ukobvu wepaipi yesimbi mudhayamita imwe chete. Zvinonyanya kuratidzwa zvehurongwa ndezvi SCH 5, 5S, 10, 10S, 20, 20S, 30, 40, 40S, 60, 80, 80S, 100, 120, 140, 160. Kukura kwetafura nhamba, ndiko kukora kwepamusoro. rusvingo rwepombi, iyo yakakwirira yekudzivirira kudzvinyirira.

Chirongwa 40, 80 simbi pombi dimension zvinoreva
Kana iwe uri mutsva muindasitiri yepombi, nei uchigara uchiona purogiramu 40 kana 80 simbi pombi kwose kwose? Rudzii rwezvinhu zvepombi idzi?
Sezvawakaverenga pamusoro zvinyorwa unoziva kuti Schedule 40 kana 80 inomiririra pombi madziro ukobvu, asi nei yaigara ichitsvakwa nevatengi?

Heino chikonzero:
Rongedza 40 uye 80 simbi pombi seaya akajairwa saizi anodiwa mumaindasitiri akasiyana, nekuda kweanowanzo dzvinyiriro yepombi idzi, dzinogara dzichibvunzwa huwandu hukuru.

Muyero wezvinhu zvepombi dzakakora zvakadaro hauna magumo, unogona kubvunza sch 40 pombi yesimbi isina tsvina, seASTM A312 Giredhi 316L; Kana sch 40 kabhoni simbi pombi, senge API 5L, ASTM A53, ASTM A106B, A 179, A252, A333 nezvimwe.

Chii chinonzi Nominal Pipe Size (NPS)?
Nominal Pipe Size (NPS) iNorth America seti yeakajairwa saizi yemapombi anoshandiswa kune yakakwirira kana yakaderera kumanikidza uye tembiricha. Saizi yepombi inotsanangurwa nenhamba mbiri dzisiri-dimensional: saizi yepombi yezita (NPS) yakavakirwa pamainch, uye chirongwa (Sched. kana Sch.).

Chii chinonzi DN (Nominal Diameter)?

Nominal dhayamita zvinorevawo kunze dhayamita. Nokuti sezvo rusvingo rwepombi rwakanyanya kutetepa, kunze uye mukati dhayamita yepombi yesimbi inenge yakafanana, saka chiyero chepakati chezvikamu zviviri chinoshandiswa sezita repaipi dhayamita. DN (zita dhayamita) ndiyo dhayamita yakajairika yepombi dzakasiyana-siyana uye pombi accessories. Iyo imwechete yezita dhayamita yepombi uye pombi fittings inogona kubatanidzwa, ine kuchinjana. Kunyangwe kukosha kuri pedyo kana kuenzana nemukati dhayamita yepombi, Haisi iyo chaiyo pfungwa yepiipi dhayamita. Saizi yezita inomiririrwa nechiratidzo chedhijitari inoteverwa netsamba "DN", uye nyora chikwata mumamilimita mushure mechiratidzo. Somuenzaniso, DN50, pombi ine zita dhayamita 50 mm.

Pipe Weight Kirasi Chirongwa
WGT kirasi (huremu kirasi) chiratidzo chepombi madziro ukobvu mukutanga, asi zvichiri kushandiswa. Ine mamakisi matatu chete, anoti STD ( standard ), XS ( yakawedzera kusimba ), uye XXS ( yakawedzera kusimba kaviri).
Kune yekutanga pombi yekugadzira, caliber yega yega ine imwe chete yakatarwa, inonzi standard tube (STD). Kuti utarise nehigh pressure fluid, iyo thickening pombi (XS) yakaonekwa. XXS (yakapetwa kaviri yakawedzera kusimba) pombi yakaonekwa inobata yakakwira pressure fluid. Vanhu vakatanga kuda kushandiswa kwepombi yakaonda-yakakomberedzwa nenyere kusvika pakubuda kwezvinhu zvitsva zvekugadzira tekinoroji, ipapo zvishoma nezvishoma yakaonekwa iyo nhamba yepombi iri pamusoro. Hukama hunofambirana pakati pechirongwa chepombi uye huremu kirasi, tarisa kune ASME B36.10 uye ASME B36.19 yakatarwa.

Nzira yekutsanangura sei simbi pombi zviyero uye saizi zvakarurama?
Somuenzaniso: a. Inoratidzwa se “pombi yekunze dhayamita × ukobvu hwemadziro”, senge Φ 88.9mm x 5.49mm (3 1/2” x 0.216” ). 114.3mm x 6.02mm (4 1/2” x 0.237”), kureba 6m (20ft) kana 12m (40ft), Single Random Length (SRL 18-25ft), kana Double Random Length (DRL 38-40ft).

b. Inoratidzwa se“NPS x Schedule”, NPS 3 inch x Sch 40, NPS 4 inch x Sch 40. Saizi yakafanana neyakatsanangurwa pamusoro.
c. Inoratidzwa se "NPS x WGT Kirasi", NPS 3 inch x SCH STD, NPS 4 inch x SCH STD. Saizi yakafanana kumusoro.
d. Kune imwe nzira, muNorth America neSouth America, kazhinji inoshandisa "Pipe Outer Diameter x lb/ft" kutsanangura saizi yepombi. SeOD 3 1/2”, 16.8 lb/ft. lb/ft iri pondo netsoka.
