Fitting and method for manufacturing a fitting
A method for manufacturing a fitting. The method steps include: providing a pipe section; pressurizing the pipe section; forming a first end of the pipe section to create a press-fit connection having a smooth-walled seat for insertion of at least one of sealing and holding elements; forming a middle section to create a pipe-like polygonal-shaped element and a thickened section adjacent to the polygonal-shaped element; and cutting in a thread on a second end of the pipe section, thereby creating a fitting having a press-fit connection and threaded connection.
1. A method for manufacturing a fitting, the method steps comprising:
providing a pipe section;
pressurizing the pipe section;
forming a first end of the pipe section to create a press-fit connection having a smooth-walled seat for insertion of at least one of sealing and holding elements;
forming a middle section to create a pipe-like polygonal-shaped element and a pair of thickened sections, the thickening occurring in an area between the polygonal-shaped element and adjacent sections, and one of the adjacent sections being a second end of the pipe section; and
cutting in a thread on the second end of the thickened pipe section, thereby creating a fitting with a press-fit connection and a threaded connection.
2. The method of claim 1 , wherein another adjacent section is the first end of the pipe section.
3. A method for manufacturing a fitting, the method steps comprising:
providing a pipe section;
pressurizing the pipe section;
forming a first end of the pipe section to create a press-fit connection having a smooth-walled seat for insertion of at least one of sealing and holding elements;
forming a middle section to create a pipe-like polygonal-shaped element and a pair of thickened sections, the thickening occurring by means of upsetting in an area between the polygonal-shaped element and adjacent sections, and one of the adjacent sections being a second end of the pipe section; and
cutting in a thread on the second end of the pipe section, thereby creating a fitting with a press-fit connection and a threaded connection.
4. The method as claimed in claim 3 , further comprising the step of creating the pipe section by hydroforming.
5. The method as claimed in claim 3 , further comprising the step of creating the pipe section by cold forging.
