Description
Claims (1)
- 두 파이프(18)(20)의 연결단부를 연결하는 지중매설관의 연결장치로서, 두 파이프(18)(20)의 연결단부상에 발포시이트(10)와 지지시이트(12)를 중첩하여 고정밴드(22)로 구속한 상태에서 발포시이트(10)를 가열발포시켜 두 파이프(16)(18)의 연결단부를 밀폐하는 것에 있어서, 발포시이트(10)가 주재료인 메탈로센 폴리에틸렌(PE)에 발포제로서 아조디카본아마이드가 혼합되고 저온압출하여 시이트상으로 제작되며, 지지시이트(12)는 폴리에틸렌 재질의 시이트로서 발포시이트(10)에 중첩되는 내면측에 편조형태의 절연피복형 전열선(14)이 매입됨을 특징으로 하는 지중매설관의 연결장치.
