Chitsulo chachitsulo Dimension 3 Makhalidwe:
Kufotokozera kwathunthu kwa kukula kwa chitoliro chachitsulo kumaphatikizapo m'mimba mwake (OD), makulidwe a khoma (WT), kutalika kwa chitoliro (Nthawi zambiri 20 ft 6 mita, kapena 40 ft 12 metres).

Kupyolera mu zilembozi tikhoza kuwerengera kulemera kwa chitoliro, kuchuluka kwa chitoliro chomwe chingathe kupirira, ndi mtengo pa phazi kapena mita.
Chifukwa chake, ndichifukwa chake nthawi zonse tiyenera kudziwa kukula kwa chitoliro choyenera.

Tchati cha kukula kwa mapaipi achitsulo

Chigawo cha Tchati cha Chitoliro mu mm monga pansipa, onani Pano pa Tchati cha Mapaipi mu inchi.

Miyezo miyeso ya chitoliro chachitsulo
Pali miyezo yosiyana yofotokozera kukula kwa chitoliro chachitsulo, OD ndi makulidwe a khoma. Makamaka ndi ASME B 36.10, ASME B 36.19.

Zogwirizana nazo ASME B 36.10M ndi B 36.19M
Onse ASME B36.10 ndi B36.19 ndi muyezo wa miyeso ya chitoliro chachitsulo ndi zowonjezera.

ASME B36.10M
The muyezo chimakwirira muyezo wa zitsulo chitoliro miyeso ndi kukula kwake. Mipope iyi imaphatikizapo mitundu yopanda msoko kapena yowotcherera, ndipo imagwiritsidwa ntchito pa kutentha kwakukulu kapena kutsika komanso kupanikizika.
Chitoliro chosiyanitsidwa ndi chubu (Pipe vs Tube), apa chitolirocho ndi chapadera cha machitidwe a mapaipi, madzi (Mafuta ndi gasi, madzi, slurry) kutumiza. Gwiritsani ntchito muyezo wa ASME B 36.10M.
Mu muyezo uwu, chitoliro Outer Diameter yocheperako 12.75 mu (NPS 12, DN 300), mapaipi enieni ndi akulu kuposa NPS (Nominal Pipe Size) kapena DN (Nominal Diameter).

Pa dzanja, kwa zitsulo chubu miyeso, kwenikweni kunja awiri ofanana ndi nambala chitoliro kwa makulidwe onse.

Kodi Schedule ya Steel Pipe Dimensions ndi chiyani?
Ndondomeko ya chitoliro chachitsulo ndi njira yowonetsera yomwe imayimiridwa ndi ASME B 36.10, ndipo imagwiritsidwanso ntchito muzinthu zina zambiri, zolembedwa ndi "Sch". Sch ndi chidule cha ndandanda, nthawi zambiri kuwonekera mu American steel pipe standard, yomwe ndi prefix ya nambala yotsatizana. Mwachitsanzo, Sch 80, 80 ndi nambala ya chitoliro kuchokera ku tchati/tebulo ASME B 36.10.

"Popeza chitoliro chachikulu chachitsulo ndicho kunyamula madziwa mopanikizika, kotero kuti m'mimba mwake mkati mwake ndi kukula kwawo kofunikira. Kukula kofunikiraku kumatengedwa ngati nominal bore (NB). Chifukwa chake, ngati chitoliro chachitsulo chikunyamula madziwo mothamanga, ndikofunikira kuti chitoliro chikhale ndi mphamvu zokwanira komanso makulidwe a khoma. Kotero makulidwe a khoma amatchulidwa mu Mapulani, kutanthauza ndondomeko ya chitoliro, yofupikitsidwa ngati SCH. Apa ASME ndiye mulingo woperekedwa ndi tanthauzo la dongosolo la chitoliro. "

Ndondomeko ya pipeni:
Sch.=P/[ó]t×1000
P ndiye mphamvu Yopangidwira, magawo mu MPa;
[ó] t Ndilololedwa kupsinjika kwazinthu pansi pa kutentha kwapangidwe, Mayunitsi mu MPa.

Kodi SCH imatanthauza chiyani pamiyeso yapaipi yachitsulo?
Pofotokozera zitsulo zachitsulo, nthawi zambiri timagwiritsa ntchito ndondomeko ya chitoliro, Ndi njira yomwe imayimira makulidwe a khoma la chitoliro ndi chiwerengero. Ndondomeko ya chitoliro ( sch. ) si makulidwe a khoma, koma mndandanda wa makulidwe a khoma. Kusiyanasiyana kwa chitoliro kumatanthauza makulidwe osiyanasiyana a khoma la chitoliro chachitsulo m'mimba mwake. Zizindikiro zodziwika kwambiri za ndandanda ndi SCH 5, 5S, 10, 10S, 20, 20S, 30, 40, 40S, 60, 80, 80S, 100, 120, 140, 160. Chiwerengero chachikulu cha tebulo, ndipamwamba kwambiri pamwamba. chitoliro khoma, ndi apamwamba kukana kuthamanga.

Ndandanda 40, 80 zitsulo chitoliro gawo njira
Ngati ndinu watsopano mumakampani a chitoliro, chifukwa chiyani nthawi zonse mumawona ndandanda 40 kapena 80 chitoliro chachitsulo kulikonse? Ndi zinthu zotani za mapaipi awa?
Monga mwawerenga pamwambapa, mukudziwa kuti Ndandanda 40 kapena 80 imayimira makulidwe a khoma la chitoliro, koma chifukwa chiyani nthawi zonse amafufuzidwa ndi ogula?

Nachi chifukwa:
Ndandanda 40 ndi 80 zitsulo chitoliro monga makulidwe wamba kuti chofunika m'mafakitale osiyanasiyana, chifukwa cha mavuto ambiri mapaipi amenewa kubera, iwo nthawizonse anafunsidwa kuchuluka kwambiri.

Muyezo wazinthu zamapaipi oterewa alibe malire, mutha kufunsa chitoliro chachitsulo chosapanga dzimbiri cha sch 40, monga ASTM A312 Gulu 316L; Kapena sch 40 carbon steel pipe, monga API 5L, ASTM A53, ASTM A106B, A 179, A252, A333 etc.

Kodi Nominal Pipe Size (NPS) ndi chiyani?
Nominal Pipe Size (NPS) ndi North America seti ya kukula kwa mapaipi omwe amagwiritsidwa ntchito pazovuta zazikulu kapena zotsika komanso kutentha. Kukula kwa chitoliro kumatchulidwa ndi manambala awiri osayang'ana mbali ziwiri: kukula kwa chitoliro (NPS) kutengera mainchesi, ndi ndondomeko (Sched. kapena Sch.).

Kodi DN (Nominal Diameter) ndi chiyani?

M'mimba mwake mwadzina amatanthauzanso m'mimba mwake. Chifukwa monga khoma la chitoliro ndi lochepa kwambiri, kunja ndi mkati mwake mkati mwa chitoliro chachitsulo chimakhala chofanana, choncho mtengo wapakati wa magawo onsewa umagwiritsidwa ntchito ngati dzina la m'mimba mwake. DN (m'mimba mwake mwadzina) ndiye m'mimba mwake wamitundu yosiyanasiyana yamapaipi ndi zida zamapaipi. Yemweyo mwadzina awiri a chitoliro ndi zovekera chitoliro akhoza cholumikizira, izo ali interchangeability. Ngakhale mtengowo uli pafupi kapena wofanana ndi m'mimba mwake wa chitoliro, sikuti tanthauzo lenileni la m'mimba mwake la chitoliro. Kukula kwadzina kumayimiridwa ndi chizindikiro cha digito chotsatiridwa ndi chilembo "DN", ndikuyika chizindikirocho mu millimeters pambuyo pa chizindikirocho. Mwachitsanzo, DN50, chitoliro ndi awiri mwadzina 50 mm.

Chitoliro Cholemera Kalasi Yolemera
Gulu la WGT (kalasi yolemetsa) ndi chisonyezo cha makulidwe a khoma la chitoliro koyambirira, koma amagwiritsidwabe ntchito. Ili ndi magiredi atatu okha, omwe ndi STD ( standard ), XS ( extra strong ), ndi XXS ( double extra strong ).
Kwa chitoliro choyambirira chopangira, mtundu uliwonse uli ndi mawonekedwe amodzi okha, otchedwa standard chubu (STD). Pofuna kuthana ndi kuthamanga kwamadzimadzi, chitoliro chokhuthala (XS) chinawonekera. Chitoliro cha XXS (double extra strong) chitoliro chinawoneka kuti chimagwira madzi othamanga kwambiri. Anthu anayamba amafuna ntchito kwambiri chuma woonda-mipanda chitoliro mpaka zikamera wa zipangizo zamakono processing, ndiye pang'onopang'ono anaonekera pamwamba chitoliro nambala. Ubale wofananira pakati pa ndandanda ya chitoliro ndi kalasi ya kulemera, kutanthauza ASME B36.10 ndi ASME B36.19.

Kodi mungafotokoze bwanji miyeso yachitsulo ndi kukula kwake molondola?
Mwachitsanzo: a. Amawonetsedwa ngati "chitoliro chakunja m'mimba mwake × makulidwe a khoma", monga Φ 88.9mm x 5.49mm (3 1/2" x 0.216"). 114.3mm x 6.02mm (4 1/2” x 0.237”), kutalika 6m (20ft) kapena 12m (40ft), Single Random Length (SRL 18-25ft), kapena Double Random Length (DRL 38-40ft).

b. Zofotokozedwa ngati "NPS x Schedule", NPS 3 inch x Sch 40, NPS 4 inch x Sch 40. Kukula kofanana ndi zomwe zili pamwambapa.
c. Zofotokozedwa ngati "NPS x WGT Class", NPS 3 inch x SCH STD, NPS 4 inch x SCH STD. Kukula komweko pamwamba.
d. Palinso njira ina, ku North America ndi South America, nthawi zambiri amagwiritsa ntchito "Pipe Outer Diameter x lb / ft" pofotokoza kukula kwa chitoliro. Monga OD 3 1/2”, 16.8 lb/ft. lb/ft ndi paundi pa mapazi.
