Embonini yensimbi, ipayipi lensimbi liyinto evamile futhi ebalulekile, esetshenziswa kabanzi ekwakhiweni, ukukhiqizwa kwemishini, i-petrochemical, neminye imikhakha. Isisindo sepayipi yensimbi sihlobene ngokuqondile nokusetshenziswa kwayo kanye nezindleko zokuhamba kwezobunjiniyela. Ngakho-ke, ochwepheshe embonini kanye nabantu abasemikhakheni ehlobene badinga ukuqonda indlela yokubala yesisindo sepayipi lensimbi.

Okokuqala, ukwethulwa okuyisisekelo kwepayipi lensimbi le-63014
Ipayipi lensimbi le-63014 liyipayipi elivamile lensimbi elingenamthungo. Izingxenye zayo eziyinhloko yikhabhoni ne-chromium. Inokumelana nokugqwala okuphezulu namandla emishini. Ngakho-ke, isetshenziswa kabanzi embonini yamakhemikhali, ukwakhiwa kwemikhumbi, i-boiler, neminye imikhakha. Ngokusho kwezindinganiso ezihlukene zokukhiqiza kanye nokucaciswa, ubukhulu bodonga, ububanzi bangaphandle kanye neminye imingcele yepayipi yensimbi engu-63014 izohluka, futhi le mingcele izothinta ngokuqondile ukubala kwesisindo sepayipi yensimbi.

Okwesibili, indlela yokubala yesisindo sepayipi yensimbi
Ukubalwa kwesisindo sepayipi yensimbi kunganqunywa ubude bayo kanye nendawo yesiphambano. Ngamapayipi ensimbi angenamthungo, indawo ye-cross-sectional ingabalwa ububanzi obungaphandle nobukhulu bodonga. Ifomula ithi: \[ A = (\pi/4) \izikhathi (D^2 - d^2) \]. Phakathi kwazo, \( A \) iyindawo ephambanayo, \( \pi \) i-pi, \( D \) ububanzi obungaphandle, futhi \( d \) ububanzi bangaphakathi.
Khona-ke, isisindo sepayipi yensimbi sibalwa ngokuphindaphinda umkhiqizo wendawo yesiphambano kanye nobude ngobuningi, futhi ifomula ithi: \[ W = A \izikhathi L \izikhathi \rho \]. Phakathi kwazo, \( W \) yisisindo sepayipi lensimbi, \( L \) ubude, futhi \( \ rho \) ukuminyana kwensimbi.

Okwesithathu, ukubala isisindo imitha 63014 steel pipe
Uma sithatha ipayipi lensimbi elingu-63014 njengesibonelo, sicabangela ukuthi ububanzi obungaphandle bungu-100mm, ukujiya kodonga kungu-10mm, ubude buyi-1m, kanti ukuminyana kungu-7.8g/cm³, khona-ke kungabalwa ngokuvumelana nefomula engenhla: \[ A = (\pi/4) \izikhathi ((100+10)^2 - 100^2) = 2680.67 \, \umbhalo{mm}^2 \]. \[ W = 2680.67 \izikhathi 1000 \izikhathi 7.8 = 20948.37 \, \umbhalo{g} = 20.95 \, \umbhalo{kg} \]

Ngakho-ke, ngokwale ndlela yokubala, isisindo sepayipi yensimbi ye-63014 singama-20.95 kg ngemitha ngayinye.

Okwesine, izici ezithinta isisindo samapayipi ensimbi
Ngaphezu kwendlela yokubala engenhla, isisindo sangempela samapayipi ensimbi sizophinde sithintwe ezinye izici, njengenqubo yokukhiqiza, ukuhlanzeka kwezinto ezibonakalayo, ukwelashwa kwendawo, njll. Ebunjiniyela bangempela, kungase kudingeke futhi ukucabangela isisindo izesekeli ezifana nezintambo nama-flanges, kanye nomthelela wokubunjwa okukhethekile nezakhiwo zamapayipi ensimbi ahlukene ngesisindo.
