Abstract

본 발명은 가스레인지 배관용 연결플랜지 및 그 제조방법에 관한 것으로, 스테인레스 환봉등을 소재로 하여 연결플랜지(2)의 보스부(4) 윗면과 이음부(5) 사이에 소정두께로 덧살(8)을 형성시켜, 상기 이음부(5)를 가스공급파이프(1)의 원부면에 형성된 설치구명(7)에 끼워넣을때 가스공급파이프(1)의 외주면과 맞닿는 부분이 가스공급파이프(1)의 외주곡면과 일치하게 되어, 완전히 접촉시켜진 상태에서 용접이 이루어질 수 있게 됨으로써, 가스의 누출이 방지되고 이음부의 구조적 강성도 향상될 수 있어 제품의 품질 및 신뢰도가 향상되게 된다.The present invention relates to a connection flange for a gas stove piping and a method for manufacturing the same, which is made of stainless round rods or the like with a predetermined thickness between the upper surface of the boss portion 4 and the joint portion 5 of the connection flange 2 (8). Is formed so that the part which abuts on the outer circumferential surface of the gas supply pipe 1 when the fitting portion 5 is inserted into the installation hole 7 formed on the distal surface of the gas supply pipe 1 is the gas supply pipe 1. By matching the outer circumferential surface of the welding, the welding can be made in a fully contacted state, thereby preventing the leakage of gas and the structural rigidity of the joint can be improved to improve the quality and reliability of the product.
