Feem ntau, hom steel yeeb nkab yog loj dua li ntawm ppr yeeb nkab. Feem ntau, cov yeeb nkab 16 sib raug rau ppr20, steel yeeb nkab 20 sib raug rau ppr25, thiab cov yeeb nkab steel 25 sib raug rau ppr32.
Cov yeeb nkab fittings tuaj yeem muab faib ua plaub hom raws li txoj kev sib txuas: lub qhov (socket) yeeb nkab fittings, threaded yeeb nkab fittings, flange yeeb nkab fittings thiab welded yeeb nkab fittings. Nws yog ua los ntawm cov khoom siv tib yam li cov yeeb nkab. Muaj lub luj tshib (lub luj tshib), flange, tee, hla yeeb nkab (hla taub hau) thiab reducer (lub taub hau loj).
Lub luj tshib yog siv los tig cov yeeb nkab; lub flange yog siv los txuas cov yeeb nkab thiab cov yeeb nkab mus rau qhov kawg ntawm cov yeeb nkab, lub tee yog siv los sau peb cov kav dej; plaub-txoj yeeb nkab yog siv los sau plaub lub kav dej; txoj kab uas hla yog siv los txuas ob lub yeeb nkab sib txawv diameters Pipeline.
Ntsuab PPR yeeb nkab fittings yog hu ua peb hom polypropylene yeeb nkab fittings, uas yog extruded rau hauv cov kav dej los ntawm random copolymerization ntawm polypropylene thiab txhaj molded rau hauv cov yeeb nkab fittings; PPR yog cov roj theem copolymerization txheej txheem uas randomly polymerizes txog 5% nyob rau hauv lub PP (random copolymerization) molecular saw PE tau dhau los ua ib tiam tshiab ntawm cov kav dej. Nws muaj kev cuam tshuam zoo thiab kev ua haujlwm ntev ntev.
