Fiberglass-reinforced thermosetting resin pipe (RTRP) is available in diameters from 1 in. to 84 in., using epoxy and vinyl ester resin systems. Centrifugally cast pipe is available in sizes from 1 in. through 14 in., and it is used, along with F-Chem filament wound pipe, where extreme corrosion resistance, strength, and durability are required. The installation cost is less expensive than steel pipes. Literature describes advanced performance, epoxy, vinyl ester, high pressure, and specialty piping systems. A chart lists the size range, pressure rating, maximum temperature, types of joints, and typical applications for each type of pipe. The brochure describes 10 different vhf communication joining systems, tools and accessories, and various fittings. our contacts and relationships allow us to provide superior product at lower cost than a single commercial user dealing direct with a single factory. let us quote on your needs! we can research and locate fiberglass products needed for your manufacturing, and in many cases suggest alternate or lower-cost solutions. quantities for wholesale price breaks can be surprisingly small, and custom colors vhf and lengths are possible as well. inquire by email or post. type 1 consists of one 8 ft. length of 1¼" od and one 8 ft. length of 1" od round fiberglass tube both having 0.125" wall. the 1" tube snugly-but-easily telescopes in-side vhf the larger tube. using a recommended 12" overlap yields a usable length of 15 feet...more than enough for 20m!! a foot of this extra length may be easily cut (with a hacksaw) from the 1" od tube, and epoxied inside the bottom of the 1¼" od tube. this yields a full ¼" wall thickness(!) at the point of greatest stress...e.g. where the clamps secure the spreaders vhf to the spreader mounting plate-or "spider".
