The construction of laboratory gas pipelines is the core link involved in the installation of gas transmission systems in laboratory construction, which requires strict design specifications and construction standards to ensure safety, stability, and maintainability. Botai editor will take you to learn about relevant knowledge.

1、 Construction process

1. Requirement analysis: Clarify the requirements for laboratory gas types, flow rates, pressures, and purity.

2. Layout optimization: adopting modular design to avoid cross interference of pipelines; Partition and arrange gas pipelines with different properties.

3. Drawing review: Conduct on-site investigation based on laboratory floor plans to confirm pipeline routing, support positions, and equipment installation points.

2、 Material preparation

1. Accessory matching: including pressure reducing valve, pressure gauge, gas leak alarm, explosion-proof device, etc., which must comply with relevant safety standards.

2. Pipe selection: Priority should be given to selectingSeamless stainless steel pipe, corrosion-resistant and suitable for high-purity gases. Copper pipes are only used for end or low purity scenarios.

3、 Security measures

1. Construction safety regulations require operators to wear protective equipment and secure ladders during high-altitude operations. The welding area needs to be well ventilated to avoid the accumulation of flammable gases.

2. Special gas processing pipelines for flammable and explosive gases such as hydrogen and oxygen need to be laid separately, using anti-static materials and equipped with check valves and alarm devices. The toxic gas pipeline is equipped with an independent exhaust system and an emergency shut-off valve.

4、 Acceptance and maintenance

1. Pressure test: Conduct airtightness testing at 1.5 times the working pressure, and maintain the pressure for 24 hours without any leakage.

2. Purity testing: High purity gas pipelines need to be tested for particle content and residual moisture to ensure compliance with instrument requirements.

5、 Precautions

1. Identification management: The pipeline is marked with gas type, flow direction, and safety warning signs.

2. Economic balance: Although the cost of centralized gas supply system is relatively high, it can reduce the risk of gas cylinder storage and improve gas supply stability.
