Nga ebyuma ebikulu ebiziyiza ebbugumu n’okutambuza ebintu mu yinginiya w’emidumu egy’omulembe, payipu z’ebyuma eziziyiza omusana zikozesebwa nnyo mu makolero g’amafuta, eddagala, n’ebbugumu. Enkola yaabwe ekwata butereevu ku bukuumi bw’enkola n’okukozesa amaanyi amalungi. Okukakasa omutindo gw’ebintu n’okwesigamizibwa kwa pulojekiti, okufulumya n’okukkiriza payipu z’ebyuma ebiziyiza omusana kulina okugoberera ennyo omutindo gw’okussa mu nkola ogukwatagana.
The main implementation standards for insulated steel pipes in my country include GB/T 29047-2012, "High-density polyethylene outer sheath pipe, polyurethane foam plastic prefabricated direct-buried insulated pipe" and CJ/T 114-2017, "High-density polyethylene Outer Sheath Pipe, polyurethane foam pulasitiika nga prefabricated direct-buried insulated payipu ne fittings." Emitendera gino giwa ebikwata ku kintu ekikwata ku payipu y’ekyuma mu bujjuvu, ensengeka y’olutimbe lw’okuziyiza (insulation layer structure), omulimu gw’ekibikka eky’ebweru, n’ebyetaago by’eby’ekikugu okutwalira awamu. Okugeza, payipu z’ekyuma zitera okutaliimu musonyi oba nga ziweereddwa mu ngeri ey’omwoyo, era ebintu birina okugoberera omutindo gwa GB/T 8163 oba GB/T 9711 okukakasa obusobozi bw’okusitula puleesa n’okuziyiza okukulukuta. Ekisenge ekiziyiza amazzi (insulation layer) kitera okukolebwa mu kiwujjo kya polyurethane ekikaluba, ekirimu obutambuzi bw’ebbugumu obutono n’amaanyi amangi ag’okunyigiriza. Obugumu bwayo n’obungi bwayo birina okutuukiriza ebisaanyizo bya dizayini okukendeeza ku kufiirwa ebbugumu n’okukuuma payipu y’ekyuma. Ekikuta eky’ebweru kitera kukolebwa mu polyethylene (HDPE) erimu ebirungo ebingi (HDPE) ekiwa obuziyiza obulungi obw’obudde n’amaanyi g’ebyuma. Emitendera giraga bulungi okuziyiza kwayo okukwata n’okuziyiza enjatika z’okunyigirizibwa kw’obutonde.
Okugatta ku ekyo, emitendera gy'ensi yonna nga ISO 23940:2019, "Puping Systems eziteekeddwawo nga tezinnabaawo," ziwa ekiwandiiko ekijuliziddwa ku bintu ebifulumizibwa ebweru w'eggwanga, okussa essira ku kukwatagana kw'ebintu n'obulamu obw'ekiseera ekiwanvu-. Mu nkola za yinginiya, omutindo gulina okulondebwa okusinziira ku mbeera ezenjawulo. Okugeza, enkola z'ebbugumu mu bibuga ziyinza okutegeeza CJJ/T 81-2013, "Eby'ekikugu ebikwata ku payipu z'amazzi agookya eziziikiddwa butereevu okusobola okufumbisa ebibuga," ate amakolero g'amafuta gayinza okunywerera ku mutindo gwa API oba ASTM omukakali ennyo.
Okunywerera ennyo ku mutindo gw’amakolero ku payipu z’ebyuma ebiziyiza omusana tekikoma ku kukakasa nkola ya bbanga ddene-term stable operation of the piping system, naye era erongoosa enkozesa y’amasoboza n’okukendeeza ku ssente z’okuddaabiriza. Olw’enkulaakulana mu tekinologiya, omutindo gujja kwongera okulongoosebwa, okuvuga okukulaakulanya payipu z’ebyuma ebiziyiza omusana okutuuka ku kukola obulungi ennyo n’omukwano ogw’obutonde.
