Tubular body having pipe joint member attached thereto with brazing ring
First Claim
1. A structure for connection to a tubular body having an internal fluid passage and having a curved, circular-arc cross section peripheral wall with a cylindrical exterior surface and having a hole extending radially therethrough from said exterior surface of said passage, comprising:
- a pipe joint member for fluid communication with the interior of said tubular body, having an internal passage extending from a first and configured for insertion into said hole in said tubular body to a second end configured for connection to a fluid pipe, and an outwardly extending flange between said first and second ends, anda separate brazing ring for positioning around said first end of said pipe joint member adjacent said flange, having a first surface for contact with said flange and having a curved second surface for contact with said exterior surface of said peripheral wall of said tubular body when said first end is inserted into said hole of said tubular body and having a hole through which passes said first end of said pipe joint member;
braze cladding means on an inner surface of said hole of the brazing ring and on said second surface of said brazing ring for connecting said pipe joint member to said tubular body by brazing such that said first ring surface if brazed to said flange and said second ring surface is brazed to said exterior surface of said tubular body.

Abstract
A tubular body having a pipe joint member attached to the peripheral wall thereof and communicating with the interior of the tubular body. The peripheral wall of the tubular body includes a curved wall portion having a circular-arc cross section and formed with a hole. The joint member has an outward flange at an intermediate portion of its length and a tubular portion positioned beyond the outward flange toward one end of the joint member and has its outer end inserted in the hole in the tubular body curved wall portion. The outward flange of the joint member is brazed to the outer surface of the tubular body curved wall portion with a brazing ring which is fitted around the joint member tubular portion and positioned outside the tubular body. The brazing ring is made of a brazing sheet including cladding of brazing material over each of its opposite surfaces and has one surface joined to the outward flange and the other surface joined to the outer surface of the curved wall portion.
