General Information

TERRA-GARD™ Piping System

TERRA-GARD is an underground piping system for distribution of hot or chilled fluids at temperatures up to 130°C. Every system is pre-engineered and factory tested before shipment. Carrier pipe is supplied in customer's choice of materials which include steel, copper, stainless steel, aluminum, brass, polyvinyl chloride (PVC), and fiberglass reinforced polyester (FRP). PVC or H.D.P.E. jacketing is standard, but customer can also specify jacketing of fiberglass reinforced plastic. Terra-Gard is shipped in 6 meter or 12 meter random lengths, with 130-150 mm of carrier pipe exposed at unit ends to facilitate field joining.

BENEFITS

Since 1910, RICWIL has devoted its activities solely to design, manufacture and installation instructions of preinsulated, prefabricated piping systems. RICWIL Terra-Gard is an inexpansive underground distribution system that will provide many years of efficient service.

Terra-Gard™ - Single Source for Entire System
Give RICWIL one purchase order for your Terra-Gard system and received a complete, engineered preinsulated system; including carrier pipe, thermal insulation, protective jacketing, fittings and joining materials to meet customer's requirements. Included with our total package are engineered installation drawings and the service of a factory trained field instructor.
Design Flexibility
RICWIL's Terra-Gard™ system is not a stock item, but rather a combination of available material that meets your specific design requirements.
Faster Installation
One delivery brings all piping materials-preinsulated and prefabricated, resulting in less material handling and storage problems. All units are part-numbered in accordance with installation drawing for easy identification, resulting an a fast, systematic installation of your system.
Reduced Field Cost
A Terra-Gard™ system is prefabricated to actual job requirements and dimensions so there is no material wastage. Prefabrication eliminates field insulating and jacketing.
Quality Controlled
RICWIL® systems must pass a rigid inspection at our plant. Preengineered and factory fabricated with modern techniques by well-trained fabricators are the customer's assurance of quality. Terra-Gard systems arrive at the job-site with all insulation protected from the elements. Insulation remains dry and efficient throughout shipping, storage, and installation.
Maximum System Efficiency
All Terra-Gard™ jackets provide a positive moisture barrier. Polyurethane foam insulation with its low K factor along with the jacket material assures minimal system heat loss or gian. RICWIL Terra-Gard represent the highest product quality and maximum installation efficiency for all buried hot, or chilled fluids up to 130°C.

Terra-Gard can be furnished with any carrier pipe to customer's specification.
