Kune zvirongwa zvakasiyana-siyana kune idzi mapaipi sezvavanobata zvakasiyana-siyana zvekumanikidzika.Kazhinji kune sch 80, 100, 120, 140 uye 160 dzine madziro anorema.Iyo inorema mudhuri mukobvu pombi isina musono dzimwe nguva inogona kuwedzera kusimba yakapetwa kaviri uye inoratidzwa seXXS kana XXS.Izvo zvinhu zvinogona kusiyana sezvo kune akasiyana mamakisi ekabhoni simbi ayo anoshandiswa kugadzira akasiyana gobvu madziro kabhoni simbi pombi mhando.Iyo yakakwira vhoriyamu, kuyerera kwakakwira, masisitimu ekudzvanya senge oiri uye gasi kutapurirana mitsara, mitsetse yemvura, uye magetsi ekudyara kutonhora masisitimu ese anoshandiswa marudzi akasiyana,
Mapaipi esimbi asina musono anonyanya kushandiswa mukuchengetedza mvura, petrochemical, makemikari, simba remagetsi, kudiridza kwekurima, kuvaka maguta uye mamwe maindasitiri.Yekutakura kwemvura: kugovera mvura uye kudhonza.Kutakura gasi: gasi rechisikigo, chiutsi, liquefied petroleum gasi.Mashandisirwo emuumbirwo: anoshandiswa semapaipi ekuputira zambuko;docks, migwagwa, zvivakwa uye zvimwe zvivakwa.
Kiyi yemhando yepombi dzesimbi dzakakora-madziro dzinofanirwa kuve dzakafanana.Kusadzora kusingadzoreki kukora kwemadziro epombi dzesimbi dzakakora zvinokanganisa kunaka uye kugona kwepombi dzesimbi, pombi dzesimbi dzakakobvu-nemadziro, uye mapaipi esimbi asina musono.Inowanzo shandiswa kune akasiyana siyana kugadzirisa uye gobvu-yakavezwa zvikamu kugadzirisa.,, yunifomu yemadziro emadziro epombi yesimbi ichakanganisa zvakananga kunaka kwemashure ekugadzirisa zvikamu, rusvingo rwepombi yesimbi yakakora haidzoreki, uye huwandu hwese hwesimbi hauna kuomarara.
Mapaipi esimbi makobvu ane dhayamita yepombi kuenda kumadziro ukobvu reshiyo isingasviki makumi maviri. Inonyanya kushandiswa papetroleum geological drill pombi, petrochemical cracking pombi, boiler pombi, mapombi anotakura nemapaipi ane hunyanzvi hwemotokari, matirakita uye. ndege.Hunhu hwepombi dzesimbi dzakakobvu-nemadziro dzisina musono dzinoenderana nekufanana kwekukora kwemadziro.
Round chubhu billet → kudziyisa → kuboora → matatu-machinjika kukunguruka, kuramba achiumburuka kana extrusion → kukurura → saizi (kana kuderedza dhayamita) → kutonhora → kutwasanudza → hydraulic test (kana kuona kukanganisa) → kumaka → kuchengetera zvinhu.
Iyo michina yeanorema wallthickness simbi mapaipi indekisi yakakosha kuve nechokwadi chekupedzisira kushandiswa kwekuita (mechanicha zvimiro) yeinorema wallthickness simbi mapaipi simbi mapaipi, uye zvinoenderana nemakemikari anoumbwa uye kupisa kurapwa kwepombi yesimbi.Naizvozvo, zvichienderana neakasiyana mashandisirwo ezvinodiwa, iyo mechanic zvimiro zveinorema wallthickness simbi pombi inounzwa zvakananga kubva kuzvinhu zvekusimba kwesimba, goho poindi, uye kureba.
1. Kusimba simba
Mukuita kwekusimba, simba guru (Fb) rinotakurwa nesample painotyoka ndiko kushushikana (σ) kunowanikwa kubva kunzvimbo yekutanga yepakati-chikamu (So) yemuenzaniso, inodaidzwa kuti tensile simba (σb), uye iyo unit iN/mm2 (MPa).Inomiririra kugona kwakanyanya kwesimbi zvinhu kuramba kukuvadzwa pasi pesimba rekumanikidza.
2. Goho poindi
Kune simbi yesimbi ine chiitiko chegoho, kushushikana uko sampuli inogona kuramba ichirebesa pasina kuwedzera kwesimba panguva yekutambanudza (inoramba iripo) inonzi iyo goho point.Kana simba richidonha, mapoinzi epamusoro uye epasi anofanirwa kusiyaniswa.Iyo unit yegoho poindi iN/mm2 (MPa).
3. Elongation mushure mekuputika
Muchiyedzo chekusimba, chikamu chehurefu hwehurefu hwegeji chakawedzera mushure mekunge sampuro yatyorwa kusvika pahurefu hwegeji yepakutanga inodaidzwa kuti elongation.Inoratidzwa ne σ, iyo unit ndeye%.
Zvigadzirwa zvinofambiswa zvakanaka, boka remari ine hunyanzvi, uye zvirinani mushure mekutengesa zvigadzirwa nemasevhisi;Isu tanga zvakare mhuri yakakura yakabatana, vanhu vese vanonamatira nemutengo webhizinesi "kubatana, kuzvipira, kushivirira" ye2019 Yakakwirira mhando Iyo China Mugadziri Anotengesa 15CrMo uye 42CrMo Alloy Seamless Simbi Mapaipi, Kugamuchira makambani anofarira kushanda nesu, isu tinotarisira. kuve nemukana wekuita nemakambani munharaunda yese kuitira kufambira mberi pamwe nemhedzisiro yakanaka.
2023 Hunhu hwepamusoroChina 42CrMo Alloy Steel Pipes uye 15CrMo Alloy Steel Tube, Tine makore anopfuura 9 echiitiko uye timu inokwanisa, takatumira zvinhu zvedu kunyika dzakawanda nematunhu pasi rese.Isu tinogashira vatengi, masangano emabhizinesi uye shamwari kubva kumativi ese epasi kuti tibate isu uye kutsvaga kushandira pamwe kuti zvibatsire.
