Description

Footing For Keeping Warmth Of Pipeline

The present invention relates to a scaffold used in the heat insulating operation of the oil pipe, and more particularly to a scaffold for oil pipe thermal insulation work fastened to the moon is fixed to the lower portion of the pipe rack supporting the oil pipe.

A pipeline consisting of steel pipes for transporting or unloading fluids such as oil and natural gas is generally called an oil pipeline, which is a state-of-the-art facility for transporting oil and gas and is an environmentally friendly and most economical transportation system.

The pipeline is a major energy source that plays a role in the industrial activities, and is responsible for the rapid and efficient transportation of oil from the producing site to the consumer, just as tap water is sent to the place where it is needed by water pipes, which is a source of convenience for people's lives.

In Korea, oil pipelines connect five oil refineries, including Ulsan and Yeosu, and six large cities, including Seoul, Daegu, Daejeon, and Gwangju, to safely and reliably transport four types of light oils, including gasoline. It transports the above.

The oil pipe 101 is constructed on the ground and installed on the pipe rack H beam 102 having a constant height and is maintained in a horizontal state for transport of the fluid.

The pipe rack H-beam 102 is generally used by bending the "H" steel in the "c" shape, and the middle portion of the bent "H" steel to the ground at both ends to maintain a horizontal level of a constant height from the ground It is buried in and installed.

Since the oil supply pipe 101 must be maintained in a horizontal state so as not to cause a problem during transportation of the fluid, the middle portion of the pipe rack H beam 102 embedded in the ground is also installed in a horizontal state.

If the oil pipe 101 is not horizontal, the fluid to be transported is directed to the oil pipe 101 having a low position, so that a high pressure is generated in the oil pipe 101 itself, which not only causes a problem in the oil pipe 101 itself but also makes it difficult to transport the fluid. Because.

The oil pipe 101 is secured on the horizontal portion that is the middle portion of the installed pipe rack H-beam 102, and thus the oil pipe 101 is also horizontally maintained by placing the oil pipe 101 on the platform.

The oil pipe 101 installed in this way is a thermal insulation work winding the insulation on the outer surface of the oil pipe 101 so as not to freeze.

Until now, the scaffold was installed at a suitable height below the oil pipe 101, and the scaffold 104 was installed on the scaffold 104, so that an operator performed insulation of the oil pipe 101 on the scaffold 110.

The scaffold 110 is used as a scaffold 110 for the worker to transport the material or the worker's passage and work.

The scaffold 110 is composed of a quadrangular frame 111 made of lightweight “c” section steel, and an upper plate 112 is formed on an upper surface of the quadrangular frame 111, and the scaffold 110 is a pallet. Becomes the shape of.

At both ends of the frame 111, a hook 113 for hanging on the scaffold base scaffold 105 is configured, and the hook 113 is configured with an outer ring 113-1 and a hook ring 113-2. .

The hook 113 has the same thickness as the outer ring (113-1) and the hook ring (113-2), the outer ring (113-1) is composed of a straight line of a predetermined length outer surface of one end of the frame (111) Are welded.
