IFAN Gas Corrugated Pipes

Understanding Gas Corrugated Pipes‌

Gas corrugated pipes are flexible stainless steel tubes used for gas distribution. Their ribbed design allows bending without kinking, making installation easier than rigid pipes. These pipes come in two types: indoor (CSST) and outdoor-rated varieties.

Primary Uses of Corrugated Gas Pipes‌

These pipes commonly connect gas meters to appliances in residential and commercial buildings. They’re ideal for running gas lines through walls or tight spaces where rigid pipes won’t fit. Some models are specifically designed for underground use.

‌Legality of External Installation‌

External gas corrugated pipes are legal when properly rated and installed. Outdoor models must have UV-resistant coatings to prevent degradation. Most jurisdictions require protective conduit for exposed sections above ground.

Key Safety Requirements‌

Externally installed gas corrugated pipe must meet strict standards. They require proper grounding to prevent lightning damage and mechanical protection from physical impacts. All connections must be accessible for inspection.

‌Regional Code Variations‌

Legality depends on local building codes. Some areas prohibit above-ground corrugated pipes entirely, while others allow them with restrictions. California, for example, requires earthquake-resistant bracing for external installations.

Proper Installation Practices‌

Qualified technicians must install external gas corrugated pipes following manufacturer specifications. This includes using correct fittings, maintaining proper bend radii, and securing pipes at regular intervals. Improper installation voids warranties and violates codes.

Advantages Over Traditional Piping‌

Corrugated pipes offer easier installation in complex layouts and better seismic performance than rigid pipes. Their flexibility minimizes stress on connections during ground movement, making them preferable in earthquake-prone regions.

Maintenance and Inspection Needs‌

Externally installed gas corrugated pipes require regular inspections for damage or corrosion. Homeowners should check for coating deterioration, especially in coastal areas with salty air. Professionals should inspect connections annually.

‌Conclusion‌

External gas corrugated pipes are legal when using properly rated materials and following installation codes. Their flexibility offers advantages over rigid piping, but requires careful installation and maintenance. Always consult local regulations and licensed professionals before installation.
