Abstract

A high-pressure wear resistant cylinder that utilizes a high-pressure field for strength is an economical method of, or device for, handling very high pressures and the pumping of abrasive and corrosive fluids. The economic considerations are so favorable, that the invention may be considered a replacement part. The invention is suitable for a variety of applications, particularly a reciprocating flow work exchanger in the well stimulation or hydraulic fracturing industry. Using a high pressure field to strengthen the external surface (outside) of a pipe that is precision honed and plated or sleeved internally (inside), it is now possible to construct various high pressure machines in a relatively inexpensive manner. This invention makes it possible to use pipe with internal operating pressures greater than their nominal operating pressure ratings permit. This invention will be used in various high pressure piping and machinery applications.

Description

CROSS-REFERENCE TO RELATED APPLICATION

[0001] The present patent application is based upon and claims the benefit of provisional patent application No. 62 / 106,668, filed on Jan. 22, 2015BACKGROUND OF THE INVENTION

[0002] Hydraulic fracturing (also hydrofracturing, hydrofracking, fracking or fraccing), is a well-stimulation technique in which rock is fractured by a hydraulically pressurized liquid made of water, sand, and chemicals. Some hydraulic fractures form naturally—certain veins or dikes are examples. A high-pressure fluid (usually chemicals and sand suspended in water) is injected into a wellbore to create cracks in the deep-rock formations through which natural gas, petroleum, and brine will flow more freely. When the hydraulic pressure is removed from the well, small grains of hydraulic fracturing proppants (either sand or aluminum oxide) hold the fractures open. Traditionally, the fracking fluid (including proppants) is delivered to the well with powerful and expensive recipro...
