Abstract
A pipeline welding shelter which includes an umbrella-like framework with a support post which supports the umbrella-like framework. Means is provided for maintaining the support post in a substantially vertical orientation when positioned on or adjacent to a pipeline. A flexible heat resistant covering encloses the umbrella-like framework. The covering is capable of withstanding limited exposure to heat from a welding torch without melting or igniting.
Claims4
A pipeline welding shelter, comprising:
- an umbrella-like framework;
- a support post having a first end and a second end, the first end engaging the umbrella-like framework;
- an elongated saddle for maintaining the support post in a substantially vertical orientation when positioned on a pipeline, the saddle being adapted to rest lengthwise upon a horizontal section of the pipeline, the saddle having a concave underlying engagement surface that fits a curvature of the pipeline and a receiver that receives the second end of the support post, the receiver being pivotally mounted to the saddle for pivotal movement about a substantially horizontal pivot axis, means being provided to lock the receiver in a substantially vertical orientation, thereby maintaining the support post in a substantially vertical orientation when the saddle is positioned on the pipeline;
- chains wrapped around the saddle and boomers for placing the chains in tension to secure the saddle to the pipeline;
- a flexible heat resistant covering enclosing the umbrella-like framework, the covering being capable of withstanding limited exposure to heat from a welding torch without melting or igniting;
- and
- a plurality of rigid vertical supports positioned at intervals around a perimeter of and depending from the umbrella-like framework, the vertical supports limiting inward movement of the covering in response to pressure exerted by wind.

A pipeline welding shelter, comprising:
- a framework;
- at least one support post supporting the framework, the at least one support post having a first end and a second end, the first end engaging the framework;
- at least one elongated saddle securable to the pipeline maintaining the at least one support post in a substantially vertical orientation, the at least one saddle being adapted to rest lengthwise upon a horizontal section of the pipeline and having a concave underlying engagement surface that fits a curvature of the pipeline and a receiver that engages the second end of the at least one support post;
- chains wrapped around the saddle and boomers for placing the chains in tension to secure the saddle to the pipeline;
- and
- a flexible heat resistant covering enclosing the framework, the covering being capable of withstanding limited exposure to heat from a welding torch without melting or igniting.
