1. Maemo a Imperial .
Imperial tšepe pipe e bontša ke motse-moholo "dn." Sizes include DN15 (4-inch pipe), DN20 (6-inch pipe), DN25 (1-inch pipe), DN32 (1-inch 2-inch pipe), DN40 (1.5-inch pipe), DN50 (2-inch pipe), DN65 (2.5-inch pipe), DN80 (3-inch pipe), DN100 (4-inch pipe), DN125 (5-intshi pipe), DN150 (6-intshi pipe), DN200 (8-intshi phaephe), le DN250 (10-intshi phaephe). Ka mohlala, phaephe ya meetse ya DN25 (25 mm) e lekana le phaephe ya Imperial 1-intshi, yeo gape e tsebjago e le phaephe ya disenthimithara tše 8 pele ga Liberation Army. Phala ya meetse ya DN15 e lekana le phaephe ya mmušo ya 1/2-intshi, yeo gape e tsebjago bjalo ka phaephe ya disenthimithara tše 4 pele ga Liberation Army. Mohlala, phaephe ya meetse ya DN20 ke maemo a 3/4" a Brithania, ao gape a tsebjago bjalo ka phaephe ya disenthimithara tše 6 pele ga mokgatlo wa tokologo.
2. Maemo a boditšhabatšhaba .
International maemo a tšepe pipe e thehiloe ho arola intshi ka likarolo tse nyenyane. Ditlhalošo di akaretša 1/8, 1/4, le 3/8 inches, e lekanago le diphaephe tše di tsebjago ka tlwaelo tša 1-intshi le 7-intshi. Bogolo bjo bonyenyane bo bontšhwa bjalo ka 1/16, 1/32, le 1/64, e sa le ka disenthimithara. Ge e le gore sebopego sa go arola le sefapanyi di ka fokotšwa (mohlala, sebopego sa palo ke 2, 4, 8, 16, goba 32), di swanetše go fokotšwa.
3. Tšepe pipe boholo ba go bala .
Difomula tša go bala boima bja mmele bakeng sa mehuta e fapanego ya phaephe ya tšhipi di a fapana. Ka tlase, Miagoo e tla tsebagatša ka boripana difomula tše mmalwa tše di tlwaelegilego tša go bala boima bja mmele:
Boima bja tšhipi bja nkgokolo (kg)=0.00617 x Bophara x Bophara x Bolelele;
Square tšepe boima (kg)=0.00785 x lehlakoreng bophara x lehlakoreng bophara x bolelele;
Boima ba tšepe e bataletseng (kg)=0.00785 x Botenya x Foreime x bolelele.
