Pipe Cleaning System and Method
Patent Number: US 10450809 Grant Date: 2019-10-22 Filing Date: 2016-01-12
Overview
This patent protects a robust containment head designed to integrate with a tubing cleaning assembly to capture and manage residue and sprayed fluids as tubing is pulled from a well. Filed January 12, 2016 and granted October 22, 2019, the disclosure—by inventors based in Borger, TX—describes a cylindrical outer body surrounding a center aperture through which tubing passes, a wiping rubber sized to the tubing diameter, a support cylinder and bottom plate that together create a watertight reservoir, and a waste aperture for controlled drainage. The assembly is engineered to work with a spraying system that loosens residue while the wiping rubber removes solids, diverting the resulting debris and fluid into an enclosed reservoir that can be evacuated through a threaded waste collar or hose.
The prosecution secured detailed structural and functional claims covering alignment of apertures, welded reservoir construction, optional top plate retention, and load-bearing support to withstand upward and downward forces during tubing removal. The resulting patent portfolio reflects precise claim drafting that protects both the component-level innovations and the practical method of cleaning and containment in field operations.
Key Features
- Sealed reservoir formed by outer body, bottom plate and support cylinder
- Wiping rubber matched to tubing for effective debris removal
- Threaded waste aperture for hose attachment and drainage
- Optional top plate and mechanical fasteners for modular use
This containment approach improves operational cleanliness and safety on well sites and offers a durable, field-ready solution for tubing handling and maintenance in the oil and gas sector.
Invention Details
Abstract: A containment head comprises a center aperture, a reservoir, a wiping rubber, an outer body, a bottom plate and a support cylinder. The center aperture comprises a central portion of the containment head configured to pass around a tubing. The reservoir comprises a space within the outer body and above the bottom plate. The containment head is configured to selectively attach to a tubing cleaning assembly.
Summary of the Invention: A containment head and a method of use are disclosed.
Said containment head comprises a center aperture, a reservoir, a wiping rubber, an outer body, a bottom plate and a support cylinder. The center aperture comprises a central portion of the containment head configured to pass around a tubing. The reservoir comprises a space within the outer body and above the bottom plate. The containment head is configured to selectively attach to a tubing cleaning assembly.
The method of using a containment head, comprising: selectively fitting a tubing cleaning assembly around a tubing, removing the tubing from a well bore, spraying a fluid at the tubing as it is extracted through the tubing cleaning assembly, cleaning a portion of the tubing, receiving a portion of a debris which is spilling from the spraying system as it is extracted from the well bore, and collecting the debris in a reservoir within the tubing cleaning assembly. The tubing cleaning assembly comprises a center aperture, the reservoir, a wiping rubber, an outer body, a bottom plate and a support cylinder. The center aperture comprises a central portion of the containment head configured to pass around a tubing. The reservoir comprises a space within the outer body and above the bottom plate. The containment head is configured to selectively attach to a tubing cleaning assembly.
