Description

TECHNICAL FIELD [0001] The present invention relates to a head position measuring apparatus for a pipe for a boiler,

The present invention relates to an apparatus for measuring a head position of a pipe for a boiler, which enables a worker to easily visually check the position of a head of a pipe for a boiler applied in cutting, cutting, or banding processing equipment for a boiler pipe .

Generally, a heat exchanger is a device that moves heat energy through heat exchange between fluids, and is widely used in various fields such as a power plant, a petrochemical industry, a general chemical industry, and a food facility.

A heat exchanger such as a condenser or a heater of a power plant is an essential facility for maintaining a power generation system that performs unnecessary residual heat removal and reheat. In particular, the steam generator is a main facility of a nuclear power plant that acts as a pressure boundary to prevent the leakage of radiation to the outside by functioning to drive the turbine and generator by converting heat energy generated from the reactor into steam through heat exchange.

The heat exchanger and the steam generator in the power plant vary greatly in size, size, and installation number of the heat pipe according to the purpose. The heat pipe used for the heat exchanger and the steam generator is made of various materials such as titanium, copper alloy, stainless steel, .

Also, a large-diameter pipe having a diameter of 89 mm or more is used as a boiler of a thermal power plant. In the production of boilers, large diameter pipes are cut to meet the desired specifications. In general, pipes are cut and improved through automation lines.

In such an automation line, the pipe loaded on the pipe rack is transferred to the conveyor, and then the pipe is transferred to the cutter to be cut at the cutter.

In addition, a large diameter pipe is connected to a steam pipe or a cooling water pipe in a plant facility such as a combined-cycle power plant or a boiler facility by welding or a condensation pipe.

In addition to the large pipes such as the pipes, the pipes used for general piping are subjected to cutting processes at their end faces, that is, head portions, for precise and easy connection of the pipes.

This cutting process is mainly performed in a special cutting machine or a lathe. In the conventional technique, the setting process for the cutting process such as positioning and moving of the pipe is checked (or visually) according to the worker's career And is proceeding.

In this way, since the worker confirms the head position of the pipe for the boiler (or eyes) and sets it, the accuracy sometimes deteriorates. Usually, the setting time of the head part of the pipe for the boiler is about 1 hour before the cutting, and the setting time is increased for every single mistake. Since the boiler pipe is large and heavy, the boiler pipe is moved by utilizing the crane, which is time consuming.

This increase in settling time leads to a cost loss due to a decrease in productivity, and therefore, there is a need to reduce the setting time before cutting the head portion of the boiler pipe. In other words, equipment that can precisely measure the setting situation is needed to prevent the quality problem of the pipe for the boiler in advance.

In addition, there is always a risk of a safety accident because the worker directly measures and confirms the setting after the head part cutting processing of the pipe for the boiler.

In other words, although the boiler head measurement location exists in the facility, the space inside the facility is narrow and slippery, and the risk is inherent, and a method for recognizing and preventing the risk is found, but the risk still exists.

Accordingly, there is a need for a method for measuring the setting status of the boiler pipe before cutting the head portion of the pipe through the display screen from the outside without entering the dangerous space by the operator.
