Je, bomba la PE linaweza kufungia ufa?

2025-08-19

Katika baridi baridi, bomba kufungia na kupasuka ni tatizo kwamba watu wengi wasiwasi kuhusu, hasa mabomba kutumika nje au katika mazingira unheated. PE bomba, kama kawaida kutumika bomba plastiki, mara nyingi kutumika katika usambazaji wa maji, mifereji ya maji na mashamba mengine. Je, kufungia na kupasuka katika maji ya baridi? Kama mtaalamu bomba mtengenezaji, AD Bomba itakuwa kuchambua tatizo hili kwa undani kwa ajili yenu.

PE bomba, yaani, bomba polyethilini, ina kubadilika vizuri na chini joto athari upinzani. Hii ni kwa sababu PE nyenzo yenyewe bado inaweza kudumisha elasticity fulani katika joto la chini, tofauti na baadhi ya vifaa brittle (kama baadhi PVC au mabomba chuma), ambayo ni kukabiliwa na brittle kupasuka katika joto la chini. Wakati maji ndani ya PE bomba kufungia, kiasi frozen ya maji kupanuka. Unyumbufu wa bomba la PE huruhusu kufanyiwa deformation ya elastic kwa kiwango fulani, na hivyo kuzuia shinikizo linalosababishwa na upanuzi wa barafu. Katika kesi ya vipimo vya ufungaji wa bomba, nafasi ya kutosha ya upanuzi na ubora wa bomba uliohitimu, bomba la PE haliwezi kupasuka kwa sababu ya kufungia wakati wa baridi.

Hata hivyo, hii haimaanishi kwamba bomba la PE halitawahi kufungia na kupasuka chini ya hali yoyote. Ikiwa maji ndani ya bomba la PE hufungia kabisa na hakuna nafasi ya bafa wakati wa mchakato wa barafu (kwa mfano, bomba limewekwa limekufa sana na haliwezi kuzalisha deformation yoyote), upanuzi wa kiasi unaoendelea bado unaweza kuzidi nguvu ya mwisho ya mvutano wa nyenzo za bomba la PE, na kusababisha kupasuka kwa bomba. Kwa kuongezea, ikiwa bomba la PE lenyewe lina kasoro za ubora, kama vile usafi usiotosha wa malighafi, unene wa ukuta usio sawa, mchakato wa uzalishaji wenye kasoro, nk, upinzani wake wa athari za joto la chini na unyumbufu utapunguzwa sana, na kuna uwezekano mkubwa wa kuharibiwa chini ya hali ya kufungia.

Ili kuzuia kwa ufanisi bomba la PE kutoka kufungia na kupasuka katika majira ya baridi, usakinishaji sahihi na matengenezo ni muhimu. Kwanza, wakati wa kuweka bomba, bomba la PE linapaswa kuzikwa chini ya mstari wa kufungia kulingana na hali ya hewa ya ndani na kina cha kufungia udongo ili kuepuka bomba kuwa moja kwa moja kwa mazingira ya joto la chini sana. Kwa sehemu zilizo wazi za bomba, kama vile mita za maji, vali na sehemu fupi za bomba zilizowekwa juu, hatua za insulation ya joto zinapaswa kuchukuliwa, kama vile kufunga pamba ya insulation ya joto, kufunga mikono ya insulation ya joto, nk, ili kupunguza upotevu wa joto na kuzuia mwili wa maji kwenye bomba kutoka kufungia. Kabla ya majira ya baridi kuja, kwa mfumo wa bomba ambao hautumiki kwa wakati huu, maji katika bomba yanapaswa kutolewa ili kuepuka uharibifu wa bomba unaosababishwa na mkusanyiko wa maji, kufungia na upanuzi.

Kuchagua bidhaa za bomba za PE za ubora wa juu ni dhamana ya msingi. Kama mtengenezaji wa bomba la kitaalamu, AD Pipe huchagua malighafi ya ubora wa juu kwa mabomba yake ya PE na hupitisha michakato ya juu ya uzalishaji na vifaa ili kuhakikisha kuwa bidhaa zina unyumbufu bora, upinzani wa athari za joto la chini na zaidi Mabomba ya AD PE hupitia ukaguzi mkali wa ubora kabla ya kuondoka kiwandani, na yanaweza kufanya kazi kwa uhakika katika mazingira mbalimbali magumu, ikiwa ni pamoja na kushughulika na changamoto za joto la chini wakati wa baridi.

Kwa muhtasari, mabomba ya PE na unyumbufu wao mzuri na upinzani wa athari za joto la chini yana hatari ya chini ya kufungia na kupasuka wakati wa baridi chini ya hali ya kawaida, lakini sio huru kabisa kutoka kwa kufungia na kupasuka. Nguvu ya upanuzi wa kiasi cha kufungia maji ni kubwa, na ni vigumu kwa bomba lolote kuhimili kikamilifu shinikizo la upanuzi lisilo na kikomo. Kwa kuchagua bidhaa za bomba za PE za ubora wa juu kama AD Pipe na kuchukua hatua za ufungaji wa kisayansi na zinazofaa, insulation na matengenezo, uwezekano wa kufungia na kupasuka kwa bomba la PE wakati wa baridi unaweza kupunguzwa kwa kiasi kikubwa, na uendeshaji salama na thabiti wa mfumo wa bomba katika msimu wa baridi unaweza kuhakikisha.
