Ingubo yangaphandle ye-3LPE DIN 30670 Ngaphakathi kwe-FBE Coating
Ingcaciso yeMveliso
I-Cangzhou Spiral Steel Pipes Group Co., Ltd inemizila emi-4 yemveliso yokuthintela ukugqwala kunye nobushushu ukuze yenze uphahla lwe-3LPE kunye nophahla lwe-FBE. Ububanzi obuphezulu bangaphandle bungaba yi-2600mm.
Ezi ngubo zilungele ukukhuselwa kwemibhobho yentsimbi egqunywe okanye engaphantsi kwamanzi kubushushu obuyilwe ukusuka kwi -40℃ ukuya kwi +80℃.
Lo mgangatho uchaza iimfuno zokugquma ezisetyenziswa kwiipayipi zentsimbi ezifakwe kwi-spirally welded kunye nezixhobo ezisetyenziselwa ukwakha iipayipi zokuhambisa ulwelo okanye iigesi.
Ukusebenzisa lo mgangatho kuqinisekisa ukuba i-PE coating inika ukhuseleko olwaneleyo kwimithwalo yobushushu kunye neyekhemikhali eyenzeka ngexesha lokusebenza, ukuthuthwa, ukugcinwa kunye nokufakwa.
Iingubo ezikhutshiweyo zineeleya ezintathu: i-epoxy resin primer, i-PE adhesive kunye ne-extruded polyethylene yangaphandle. I-epoxy resin primer isetyenziswa njengomgubo. I-adhesive ingasetyenziswa njengomgubo okanye ngokukhutshelwa ngaphandle. Kwiingubo ezikhutshiweyo, umahluko wenziwa phakathi kokukhupha imikhono kunye nokukhutshelwa kweshiti. Iingubo ze-polyethylene ezikhutshiweyo ziinkqubo zodwa okanye ezininzi. Umgubo we-polyethylene udityaniswe kwinxalenye eshushu kwangaphambili de kufikelelwe kubukhulu obufunekayo bokukhutshelwa.
Iprimer ye-resin ye-epoxy
I-epoxy resin primer kufuneka isetyenziswe ngendlela yomgubo. Ubukhulu obuncinci bomaleko yi-60μm.
Iglu ye-PE
Iglu ye-PE ingafakwa kwimo yomgubo okanye ikhutshwe. Ubukhulu obuncinci bomaleko yi-140μm. Iimfuneko zamandla exolo ziyahluka ngokuxhomekeke ekubeni iglu isetyenzisiwe njengomgubo okanye ikhutshwe.
Ukwambathisa ngepolyethylene
Ingubo yepolyethylene ifakwa ngokusila okanye ngokukhutshelwa kwesleeve okanye ishiti. Ingubo kufuneka ipholiswe emva kokusetyenziswa ukuze kuthintelwe ukuguquka okungafunekiyo ngexesha lokuthuthwa. Ngokuxhomekeke kubukhulu obuqhelekileyo, kukho amaxabiso ahlukeneyo amancinci ubukhulu obuqhelekileyo bengubo. Kwimeko yokwanda kwemithwalo yoomatshini ubukhulu bomaleko obuncinci buya kwandiswe nge-0.7mm. Ubukhulu bomaleko obuncinci bunikwe kwitheyibhile 3 ngezantsi.
