Abrasion resistant frac head
First Claim
1. A frac head, comprising:
- a main body having a lower end, an upper end, and an internal bore;
plural side entries oriented around the main body such that flow from each of the side entries meets flow from an opposing side entry in the internal bore;
the plural side entries being oriented to produce a flow in a downstream direction through the internal bore towards the lower end of the main body; and
a replaceable abrasion resistant wear sleeve secured in the internal bore downstream of the side entries and positioned to intercept flow from the side entries and prevent the flow from impacting directly on material of the main body.

Abstract
A frac head comprising a main body with plural side entries oriented around the main body such that flow from each of the side entries meets flow from an opposing side entry in the internal bore. A replaceable abrasion resistant wear sleeve is secured in the internal bore of the main body downstream of the side entries and positioned to intercept flow from the side entries and prevent the flow from impacting directly on material of the main body. The side entries terminate at the internal bore equidistantly from the lower end of the main body, and are symmetrically arranged around the main body. The side entries are oriented at about 45° to the downstream direction. The replaceable abrasion resistant wear sleeve is held against movement downstream by abutment of a shoulder on the replaceable abrasion resistant wear sleeve against a shoulder on the frac body, and has a tapered internal bore.
