Hauv kev xaiv thiab kev txiav txim siab- ua cov txheej txheem rau cov kav dej insulated, yooj yim piv cov nqi yuav khoom feem ntau luv luv - pom. Kev tswj tus nqi tiag tiag nthuav dav tag nrho lub neej ntawm cov raj xa dej, los ntawm kev tsim khoom thiab tso rau ntau xyoo ntawm kev ua haujlwm thiab kev saib xyuas. Cov txheej txheem tshuaj tsuag txheej thiab qhwv cov yeeb nkab insulated, los ntawm nws txoj kev tshiab peb - txheej txheej kev sib koom ua ke, sib sib zog nqus kev ntseeg tau thiab kev lag luam, ua tiav cov txheej txheem ntev - txuag nyiaj rau cov haujlwm.
Qhov pib ntawm nws tus nqi -txuag logic yog nyob rau hauv qhov tseeb ntawm ntau lawm. Cov txheej txheem no siv polyurethane ua npuas dej ntawm cov yeeb nkab steel ntawm qhov qub. This process is like "tailor-made" for the pipeline insulation layer, resulting in uniform foam density, stable performance, and, more importantly, precise material feeding according to calculations. Los ntawm qhov chaw tsim khoom, nws txo qis cov khoom siv raw khoom pov tseg thiab ncaj qha txo cov nqi ntawm cov khoom siv.
Qhov kev xav meej no tseem txuas ntxiv mus rau kev tsim cov txheej txheem tiv thaiv sab nrauv. Cov txheej txheem tshuaj tsuag txheej thiab qhwv txheej txheem rov qab los rau kev ua haujlwm ntawm cov txheej txheem tiv thaiv sab nrauv, tsom mus rau nws cov tub ntxhais tsis muaj dej tsis zoo thiab kev tiv thaiv kev ua haujlwm. Los ntawm kev tshawb fawb txog kev tsim qauv thiab kev suav, cov txheej txheem tiv thaiv sab nrauv yog optimized thiab thinned thaum ua kom muaj kev tiv thaiv txaus rau kev puas tsuaj xws li tsheb thauj mus los, hoisting, thiab backfilling kev tsim kho. Qhov no tsis tsuas yog txo tus nqi ntawm polyethylene siv, tab sis qhov tseem ceeb tshaj, nws zam qhov kev ntxhov siab hauv sab hauv thiab nkig cracking txaus ntshai los ntawm blindly thickening txheej, ua tiav qhov sib npaug ntawm tus nqi thiab kev ntseeg siab nrog "tsuas yog" kev tiv thaiv.
Lub peev xwm loj tshaj plaws rau kev txuag nqi yog nyob rau hauv lub sijhawm ntev - lub neej ua haujlwm ntawm cov kav dej. Cov txheej txheem no siv cov ntawv polyethylene yaj extrusion thiab txheej txheej cimferential winding los tsim cov txheej tiv thaiv sab nraud. Txoj kev no tshem tawm tag nrho cov ntsiab lus kev ntxhov siab uas yuav tshwm sim nyob rau hauv cov tsoos prefabricated yeeb nkab shells los yog longitudinal welds, zoo tiv thaiv lub zais txaus ntshai ntawm longitudinal cracking. Kev txhim kho zoo ntawm cov txheej txheem tiv thaiv sab nrauv txhais tau hais tias thawj kab ntawm kev tiv thaiv cov raj xa dej tsis zoo thiab kev tiv thaiv corrosion yog qhov muaj zog heev, yog li txo qhov kev pheej hmoo thiab cov nqi loj ntawm kev kho thaum muaj xwm txheej ceev, hloov, lossis txawm tias kaw tag nrho cov kav dej vim dej nkag mus rau hauv cov txheej txheem rwb thaiv tsev, uas ua rau txo cov nqi kho mob.
Hauv cov ntsiab lus, cov txheej txheem tshuaj tsuag thiab cov txheej txheem winding tsis coj tus nqi txo qis hauv ib qho 环节 (txuas / kauj ruam), tab sis theej tus nqi optimization thoob plaws tag nrho lub neej voj voog ntawm cov kav dej. Nws tshem tawm cov khoom pov tseg ntawm qhov chaw los ntawm kev tsim khoom raug, ua kom muaj txiaj ntsig tiv thaiv los ntawm kev tsim qauv, thiab ua kom muaj kev tiv thaiv kev pheej hmoo yav tom ntej nrog nws cov kev ua haujlwm zoo dua. Xaiv cov thev naus laus zis no tseem ceeb muab kev lees paub zoo rau lub sijhawm ntev - kev ua haujlwm ruaj khov thiab kev lag luam tag nrho ntawm cov kav dej.
