Fitting and method for manufacturing a fitting
A fitting for connecting pipes together. The fitting includes a press-fit connection including a ring-shaped seat configured to receive at least one of sealing and holding elements. The fitting is configured to be sealingly connected to an inserted pipe end. A threaded connection is configured to be connected to a pipe by a thread on the threaded connection. The fitting is a single piece and is devoid of weldments.
1. A fitting for connecting pipes together, the fitting comprising:
a press-fit connection including a ring-shaped seat configured to receive at least one of sealing and holding elements and which is further configured to be sealingly connected to an inserted pipe end;
a threaded connection which is configured to be connected to a pipe by a thread on the threaded connection;
a middle section formed as a tubular polygonal-shaped element and located adjacent the threaded connection;
the middle section includes a plurality of individual portions which are thickened relative to a remaining portion of the middle section, the remaining portion being located between the thickened plurality of individual portions; and
wherein an adjacent section contiguous to one of the individual portions is the threaded connection.
2. The fitting as claimed in claim 1 , wherein the fitting is made from a material selected from the group consisting of copper, copper alloys, and steel.
3. The fitting as claimed in claim 1 , wherein the fitting is made from copper having a purity of over 99.8%.
4. The fitting as claimed in claim 1 , wherein the polygonal-shaped element is shaped as a hexagon.
5. The fitting as claimed in claim 1 , further comprising an additional adjacent section contiguous to one of the individual portions, such additional adjacent section being a cylindrical section.
6. The fitting as claimed in claim 5 , wherein the fitting is made from a material selected from the group consisting of copper, copper alloys, and steel.
7. The fitting as claimed in claim 5 , wherein the fitting is made from copper having a purity of over 99.8%.
8. The fitting as claimed in claim 1 , wherein the fitting is formed as a single piece devoid of weldments.
