Embodiment

[0054] Such as figure 1 As shown, the present invention is mainly applied to rocket propellant, especially the pipeline installation aspect of rocket RP-1 propellant delivery system. When the present invention is applied to the rocket RP-1 propellant delivery system, the process of its implementation is mainly divided into the following parts:

[0055] (1) Cleaning of pipes, valves and fittings

[0056] Pipes, valves and pipe fittings must be degreased and cleaned in strict accordance with the requirements before installation. The cleaning site should be a well-built factory building and a room that can be sealed around the floor. The ventilation conditions should be good. The site environment should be clean and dry. The tools used should be clean. Operators must wear clean work clothes and rubber gloves to prevent Ensure the quality of cleaning work.

[0057] Cleaning agent: industrial alcohol is preferably used in this embodiment.

[0058] Auxiliary tools: PSI pipeline ...

Abstract

The invention discloses a pipeline installation construction method for a rocket RP-1 propellant feed system. The pipeline installation construction method solves the problems that as for an existing pipeline installation construction mode of a rocket RP-1 propellant feed system, construction efficiency is low, cost is high and potential safety hazards exist. The pipeline installation construction method comprises the first step of cleaning pipes, valves and pipe fittings, the second step of pipeline machining, the third step of bend machining, the fourth step of pipeline installation, the fifth step of installing an air supply pipeline, the sixth step of installing propellant filling pipeline supports, the seventh step of installing pipeline auxiliaries, and the eighth step of pipeline heat preservation. The pipeline installation construction method for the rocket RP-1 propellant feed system is reasonable in design and perfect in construction technology, solves a lot of problems existing in a propellant feed system pipeline system, well improves construction efficiency, lowers construction cost and therefore has high application value.

Description

technical field [0001] The invention relates to a construction method, in particular to a pipeline installation construction method for a rocket RP-1 propellant delivery system. Background technique [0002] Rocket propellants are typically stored in bulk in some form in propellant containers, which are ejected in bulk from the rocket engine in the form of fluid jets, producing thrust as propulsion. The fuel propellant (RP-1 highly refined kerosene) tends to burn with the oxidizer propellant to produce a large amount of very hot gas, which expands and is ejected from the nozzle, accelerating, rushing out of the bottom of the rocket to generate thrust until the rocket reaches extremely high speeds . [0003] Due to the particularity of the high quality requirements of the RP-1 fueling system for rockets, the requirements for the material control, hanger setting, welding process, installation procedure, and system cleaning of the stainless steel pipe filling system are very h...
