Remark:  1.  The blue color type we have supply already

  1. 2. Galvanized spiral pipe with 100g galvanized.
  2. 3. PU with fire resistant class B
  3. 4. Internal seamless pipe with SCHEDULE 40 standard.

Closed cell polyurethane insulation offering the lowest available thermal conductivity and best natural resistance to water penetration. 

Galvanized spiral outer jacketing protecting the insulation from erosion and acting as a vapor barrier against water intrusion or condensation. 

Engineered coupling and fitting insulation kits providing the same level of moisture resistance and insulation protection. 

Reduced installation risk to building and workers using convenient pre-insulated joints and fittings kits installed with a fraction of the labor. 

Improved owner confidence in installation quality using a system, with the exception of the couplings and fittings, completely insulated at our plant. 

Long-term energy savings over the life of the system with the superior insulating capabilities of polyurethane insulation.
