1. Before installation and commissioning, be sure to study the relevant installation manual and strictly follow its provisions.  
2. Before construction preparation, ensure installation conditions are met; ensure building structure is understood and plans/countermeasures developed accordingly; ensure pipes/fittings meet standards and contaminants removed; ensure tools available and personnel trained and familiar with operations.  
3. During construction, always pay attention to key points in the manual; strictly follow steps for safe, orderly, scientific installation; during pipeline laying, meet laying condition requirements.  
4. After installation, pipeline system requires pressure testing acceptance; pressure testing process must comply with manual regulations; follow specified hydrostatic testing steps per manual.  
5. After completion, perform item-by-item acceptance per manual, document, and properly store records.

1. AIRPIPE super corrosion-resistant carbon steel pipe series are mainly applied to fire protection, HVAC, drainage, gas and other industries. The main dimensions of double grooved type are DN15-DN100; the boss pipe hoop connection type is DN65-DN250.
2. Pre-installation inspection. Before installation, check whether the material surface is intact, free of cracks, oxidation, deformation or obvious scratches. For profiles, ensure uniform cross-section to avoid material defects affecting installation quality. Clean the surface before installation, remove dust and oil stains, and use appropriate cleaners for treatment.
3. Construction requirements. Cutting should use special tools suitable for the material to ensure processing quality and avoid unnecessary thermal influence. More advanced processing methods can be adopted for high-precision installation. Cutting error should be controlled within a reasonable range, and the cutting surface should be smooth without obvious deformation. Meanwhile, carry out deburring and chamfering treatment to reduce installation stress and improve connection quality.
4. Air tightness and pressure testing. For gas pipelines, conduct air tightness testing to ensure no leakage under specific pressure. For liquid pipelines, conduct pressure testing to ensure stable operation within the design requirements. Testing methods and parameters can be adjusted according to specific application needs.

1. The super corrosion-resistant carbon steel pipeline system shall be entirely made of carbon steel pipes, pipe fittings and accessories. When connected with pipes, pipe fittings and accessories of other materials, measures shall be taken to prevent electrochemical corrosion.
2. For the super corrosion-resistant carbon steel pipes laid underground, anti-corrosion measures shall be taken for the outer wall of the pipeline.
3. The service pipe should not pass through the foundation of the building. When passing through the exterior wall, holes shall be reserved, sleeves shall be laid, and adverse factors such as building settlement shall be considered.
4. The pipeline shall not be cast in the reinforced concrete structure layer.
5. The pipeline should not pass through the settlement joints, expansion joints and deformation joints of the building. When it is necessary to pass through, devices to compensate for pipeline expansion and shear deformation shall be set up.
6. The pipeline shall not be laid in the power distribution room, strong and weak electrical pipeline wells, flues, air ducts and drains.
