Sare u leh Helita Hantiya iyo Jiritaanka Dahsoon
Gudburka odoo la dhiso kan dhulka hoose ee qoladaha hdpe double wall corrugated waxa ay leedahay tijaabo siinida ugu wanaagsan sababtoo ah salka dhexeerdooda caadi ah oo lagu sameeyey si kalsoonid ah inay ka buuxiyaan xumaantooda iyo inay kordhibaan hawlaha kororinta. Khalaajadda tijaabada siinida aysan ku jira inay kordhiyaan shaqada nidaamka, kala duwiddii qiimaha pump-ka, iyo kordhinta guud ee tijaabada siinida marka loo isticmaalayo nidaamka kororinteed iyo nidaamka guduudinta. Salka dhexeerdooda caadi ah ee qoladaha hdpe double wall corrugated waxa ay leedahay koofishent kala duwan ee Manning's oo yar sana san compared to concrete, steel, or clay pipes, allowing for higher flow velocities and greater carrying capacity within the same pipe diameter. Khalaajadda tijaabada siinida waxa ka dhaca in qolado fudud oo gaaban ayaa loo isticmaali kara in lagu helo kororinti kama ay tahay qolado weyn tradiitional, taasoo muujinaya in ka duwiddii qiimaha lakoobka, kala duwiddii qiimaha daaqda, iyo fudud-dhigga shaqada dhiso. Habka abuurista wuxuu xaqiijinayaa awoodda salka dhexeerdooda, iskudhafka xalinta iyo qoladaha aan lahayn inay abuuraan turbulens ama inay ka dabaalato kororinti qoladaha aan lahayn. Aragti khafiifinta nafsiyeed ee qoladaha hdpe double wall corrugated waxa ay leedahay inay ilaaliyaan kaga furinta dhulka iyo abuurinta qolo, ka duwiddii shaqada ilaaliynta, ilaa kordhinta shaqada raaxaysiga dhererka. Xooloogga kimikada ee materialka HDPE wuxuu ilaaliyaa in salka dhexeerdooda ka bilaabi karo oo kale waxa ay suurtoonaan inay ka bilaabiyaan qoladaha fulwaan iyo qoladaha chunjiyaha, ilaa kordhinta tijaabada siinida ugu wanaagsan dhererka muddada shaqaysa. Tijaabada kororinta muujinayaa in qoladaha hdpe double wall corrugated waxay ilaaliyaan tijaabada siinida oo kale marka la soo dirirayo sannadaha, iyadoo la mid ah waxyaabaha kala duwan oo kale waxay habboon karaan scale, corrosion, or biological growth that impedes flow. Salka dhexeerdooda caadi ah waxa ay kalsooniyaan shaqada fiirinta iyo saafinta marka loo baahan yahay, in lagu oggolaayo tilmaamo ilaaliynta inay u socotaan si degdeg ah nidaamka qolada. Qeexidda advanced computational fluid dynamics modeling wuxuu muujinayaa in qoladaha hdpe double wall corrugated waxay leedahay aragti kororinta laminar ee ka dabaalata inay ka dabaalato shaqada iyo kordhinta tijaabada nidaamka kaliya oo kale kororinti iyo istimaamka.
