Installation method of seamless boiler pipe

Installation method of seamless boiler pipe

Preparations before installation

Before starting to install boiler seamless pipes, you need to carry out pre-installation preparations, including measuring the boiler seamless pipes, preparing pipe connection accessories, etc.

1. Measure the size

Before installation, it is necessary to measure the size of the seamless pipe of the boiler to ensure that the size and shape of the connecting pipe match the boiler, and to determine the installation position of the connecting pipe.

2. Prepare pipe connection accessories

Prepare pipe connection accessories that match the boiler seamless pipes and inspect them to ensure they are of correct quality.

cutting seamless steel pipe

When cutting the pipe where the boiler seamless pipe is located, you need to pay attention to the following points when cutting:

1. The cutting of boiler seamless tubes should be flat and the cuts should be smooth to avoid friction and wear.

2. The cut boiler seamless tubes should be clean for subsequent assembly operations.

Install seamless pipe

Install pipe connecting accessories on the cut boiler seamless pipe, and assemble the seamless pipe and boiler connector. The specific operation process is as follows:

1. Install pipe connection accessories

First, select pipe connection accessories of appropriate size and install them strictly in accordance with the installation instructions provided by the accessory manufacturer.

2. Assemble the connecting pipe and boiler connector

When assembling the connecting pipe and the boiler connector, attention should be paid to the operating methods and precautions:

(1) Operation method

First, place the flange of the connector vertically on the connection port; secondly, place the rubber pad between the flanges; then, use appropriate screws to fix them together and use a torque wrench to tighten.

(2) Precautions

Pay attention to maintaining the verticality of the flange during assembly to avoid distortion, which will affect the quality of the connecting pipe; pay attention to using the correct wrench to avoid damaging the threads, etc.

welding

After completing the assembly of seamless  steel pipes and boiler joints, the final welding operation is required. The specific operation process is as follows:

1. Prepare welding equipment

Prepare welding equipment and required materials, including welding electrodes, etc.

2. Start welding

Only when the welding equipment is ready can welding operations be carried out to avoid unnecessary accidents.

Post-installation inspection

After completing the welding operation, the installed connecting pipe also needs to be inspected to ensure the quality of the connecting pipe. The following points need to be noted during inspection:

1. Check for leaks at connections, including in and around pipes.

2. Check the welding quality to prevent spatter, cracks and other phenomena.

3. Clean the site and keep it tidy.

The above is the installation method of boiler seamless pipes. The complete installation process includes measurement, cutting, assembly, welding and post-installation inspection. When installing, you should follow the operating procedures and strictly abide by the precautions to ensure installation quality and safety.
