Flange, imadziwikanso ngati chiyanjo kapena chowala. Chingwe ndi gawo lomwe limalumikizira shafts ndipo limagwiritsidwa ntchito polumikiza mapaipi; Chothandizanso ndi zotupa papepala ndi zida, zogwiritsidwa ntchito polumikiza zida ziwiri, monga gearbox zimachitika. Kulumikizana kwa Flange kapena kulumikizana kolumikizidwa kumapangidwa ndi kuphatikiza kwa maboti, ma gasts, ndi ma bolts olumikizidwa pamodzi ngati kapangidwe kolumikizirana. Chingwe cha mapaipi chimatanthawuza kumenyedwa komwe kumapereka zida za mapaipi, ndipo zikagwiritsidwa ntchito pazida, zimangotanthauza kulowera ndi zokongoletsera. Malinga ndi mitundu yosiyanasiyana ya mavudzi, zoponderezedwa ndi magawo osiyanasiyana opanikizika zimakonzedwa mu mapaipi. Pankhani imeneyi, mainjiniya aku Germany kuchokera ku Lard Lade amayambitsa magawo angapo omwe amagwiritsidwa ntchito molingana ndi miyezo yapadziko lonse:

Malinga ndi ASME B16.5, zitsulo zopondera zili ndi mabatani 7: kalasi150-600-600-900-900-900-900-900-900-900-900-900-900-900-900-900-900-2500 .0, PN6.4, PN10, PN16, PN25, PN32MPA)

Kusaka kwa mabizinesi kukuwonekeratu. Ma flanges300 amalimbana ndi zokulirapo kuposa kalasi150 chifukwa kalasi ya kalasi ya kalasi ya 3500 imayenera kupangidwa ndi zida zambiri kuti zizitha kupirira zovuta zambiri. Komabe, mphamvu zopsinjira zimayendetsedwa ndi zinthu zambiri. Kukhazikika kwa mpweya kumafotokozedwa m'mapaundi, ndipo pali njira zosiyanasiyana zoyimira mawonekedwe. Mwachitsanzo, matanthauzidwe a 150lb, 150lbs, 150 #, ndi kalasi150 ndi yomweyo.
