Abstract
A hammer union is provided for reducing and, in most instances, eliminating the likelihood of sealing ring displacement during fluid operations. The hammer union comprises a male pipe member, a union nut placed over the male pipe member, a female pipe member, and a sealing ring. The female pipe member includes a sealing pocket having an arcuate portion, a vertical portion, a base, and a recessed groove. The sealing ring is captured between the male pipe member and the female pipe member such that the sealing ring engages the sealing pocket of the female pipe member at each of the arcuate portion, the vertical portion, the base, and the recessed groove.
Claims20
A hammer union comprising:
- a male pipe member;
- a union nut placed over the male pipe member,
- a female pipe member, the female pipe member having a sealing pocket, wherein the sealing pocket includes a first portion, a vertical portion, a base, and a recessed groove;
- and
- a sealing ring captured between the male pipe member and the female pipe member, where in the sealing ring engages the sealing pocket of the female pipe member at each of the first portion, the vertical portion, the base, and the recessed groove, wherein prior to assembly the sealing ring has a cross-sectional area characterized as a quadrilateral with a lower end and an upper end.
A method of assembling a hammer union comprising:
- sliding a union nut over a male pipe member;
- positioning a sealing ring within a sealing pocket of a female pipe member, the sealing pocket having a first portion, a vertical portion, a base, and a recessed groove;
- positioning the female pipe member adjacent to the male pipe member;
- securing
- the male pipe member to the female pipe member with the union nut;
- and
- deforming the sealing ring by generating an axial force against the union nut thereby forcing and capturing a portion of the sealing ring between the male pipe member and the female pipe member, wherein prior to assembly the sealing ring has a cross-sectional area characterized as a quadrilateral with a lower end and an upper end.
