An apparatus and method for puncturing a pipe in-situ is presently disclosed. The apparatus has an actuator in communication with a remote controller. A firing assembly has a firing chamber and a firing pin, wherein the firing pin is in communication with the actuator. The firing chamber is configured to hold and fire a bullet radially toward the pipe, upon the firing pin being actuated with the actuator. The method includes the steps of inserting a pipe puncturing apparatus into a pipe, activating an actuator, communicating the activation of the actuator to a hammer and moving a firing pin in the hammer to impinge a cartridge and fire a bullet.

A system for pumping lubricant in a gas transportation pipeline includes a pipeline robot and a control terminal system. The pipeline robot includes a lubricant position detection, module, a lubricant pumping module, an electro-hydraulic control system, a data acquisition and processing system, and a lubricant sucking port. The location at which the lubricant deposits can be detected online, and the lubricant staving in the gas transportation pipeline can be removed in real time. The system is highly automatic and efficient. Resistance against the natural as transportation is reduced effectively, the efficiency of transporting the natural gas is improved, and safety of transporting the natural gas is ensured.

A pipeline connector that is piggable and is reinforced against deformation. At the point where the connector diverges from one pipeline to multiple pipelines, the connector may be surrounded by a tube, forming a space between the connector and the tube. The space may be filled with filler material, such as grout. Thus, radial pressure from the contents of the pipeline may be borne by the tube rather than the connector at the point of divergence. The ends of the tube surrounding the connector may be covered by plates, which may enclose the grout-filled space and which may act as feet for the pipeline connector.

Systems and methods of this disclosure make use of positive pressure to evacuate pipeline product contained within an isolated section of pipeline. In embodiments, an inert fluid is injected at a first location along the isolated section at a pressure above that of a non-isolated section of pipeline The displaced pipeline product, which may be filtered, then flows out of the isolated section at second location along the isolated section and into the non-isolated section. In other embodiments, a pressure differential between the isolated and non-isolated sections is created by lowering a pressure of the non-isolated section below that of the isolated section. The pipeline product may be a liquid, a gas, or a mixture of the two. The composition of product may be monitored as it flows through the isolated section or as it exits the section. Evacuation may be slowed or stopped based upon the composition.
