Isendlalelo sokuqala: ipayipi elingenamthungo (GB 8163-87) Kuvunguza ipayipi lelded (GB {{{1 {{4 . Ngemuva kokuthola ipayipi lensimbi I-SA 2 ku-GB 8923-1988 Izinga lejwayelekile, futhi ubulukhuni obungaphezulu bungafinyelela ama-microns r =12.5 ku-GB .
Isendlalelo sesibili: Usendlalelo we-polyurethane wokufakelwa komshini we-foam ophakeme emgodini owenziwe phakathi kwe-tube yensimbi kanye ne-tube ye-tube folsoof " I-Net . Lapho amazinga okushisa okudlulisela okuphakathi
Isendlalelo sesithathu: Ingqimba ephakeme ye-polyethylene evuthayo eyakhiwe kabusha yaba wugqinsi odongeni olumnyama (ophuzi) lokuvikela ungqimba olungenazinye izigqila lwe-polyurethane kusuka kumonakalo onzima we-polyurethane, owesibili ulwa namanzi .
I-Polyethylene Jacket Pipe yenziwa nge-polyethylene ephakeme ye-polyethylene ebonakalayo kanye nokuqina okuphezulu kakhulu nokuphikiswa okunamandla, okungavikela umbhobho ongenziwa nge-antioxidant, i-ultraviolet stabilizer kanye nekhabhoni emnyama .
