Installation and operation for boiler steel pipes

For any boiler equipment, pipelines are essential for its operation. To ensure safe and stable functioning, the installation of boiler steel pipe must adhere to relevant regulations and practical considerations.

Key points to remember include:

Compliance with Regulations: The installation of boiler pipelines must comply with the "Safety Technical Supervision Regulations for Organic Heat Carrier Furnaces" and "Technical Supervision Regulations for Pressure Pipeline Installation". Installation should follow the manufacturer's instructions and the provided piping system diagram.

Quality of Materials: The main materials and welding materials for the pressure pipeline must have corresponding quality certificates and material marks. During installation, pipeline connections should be welded as much as possible, except for the flange of the boiler, ensuring high welding quality.

Pipeline Layout: Boiler tubes should maintain a certain slope. Install an exhaust port at the higher point and a drain port at the lower point to facilitate smooth circulation within the boiler. Generally, 20# seamless steel pipes are used, along with appropriate gaskets, flanges, and other accessories.

Structural Integrity: To ensure normal boiler operation, the pipeline weight must not rest on the boiler body or the hot oil circulation pump. Consider the thermal expansion of the hot oil pipeline. After installation, conduct air pressure or hydraulic tests on all boiler pipelines, except for the expansion tank, oil storage tank, and oil and gas separation, which are not tested. Only after passing these tests should the system be put into operation.

Insulation and Coating: Do not apply coating measures at the flange connections of the boiler pipelines. The rest of the pipeline can be insulated and colored according to relevant regulations. Good insulation helps the boiler function efficiently and provides a reliable heat source for work or living spaces.

Boiler Steel Pipe Connection Methods

The connection methods for boiler tubes include:

Threaded Connection: Pipes and fittings are connected using threads. Common methods include threaded connections and tapered threaded connections.

Flange Connection: Pipes are connected using flanges. Common methods include flange butt welding connections and flange bolt connections.

Welding Connection: Pipes and fittings are connected through welding. Common methods include butt welding connections and plug welding connections.

Clamp Connection: Pipes and fittings are connected using clamps. Common methods include clamp bolt connections and clamp fastening connections.

Pipe Joint Connection: Pipes and fittings are connected using pipe joints. Common methods include pressure pipe joint connections and quick-installation pipe joint connections.

The choice of connection method depends on specific circumstances and requirements.
