0 9 <br />Primary Piping System Installation <br />'PART ONE <br />INSIALLATION INSTRUCTION FOR <br />RED THREAD IIA <br />PRIMARY PRODUCT PIPING <br />• Proper installation is the key to achieving a higitily <br />reliable, adhesive bonded, matching taper, bell and <br />spigot joint. <br />• Matching toper angles an spigot and bell ends make ll <br />possible to lock up a joint by wedging the spigot into <br />the bell so that it takes significant fbrce to separate them. <br />Proper lock up is essential. <br />• A very thin One of adhesive (called the bond line or <br />glue One) betweeri the two matching tapered surfaces is <br />necessary to achieve optimum joint strength. <br />• Cad weather Irmtallations require differant bonding <br />procedures from warm weather installations. <br />• Proper installation results In joint strength equivalent to <br />or stronger than the piping systems. <br />• To achieve the most reliable piping system, It Is <br />essential Umd the Installadon crew be familliar with <br />the joining techniques described in this manual. <br />• Proper and safe methods of testing are recommended <br />to assure the bonded joints in the piping system have <br />been properIly bunded and cured. See pages 12-13 and <br />23. <br />JOINING SYSTEMS <br />The adhesive bond- Pipe -to -Fittings <br />ed, tapered bell and <br />spigotjoint isthe primary <br />joining method for 2"-4" <br />(50 mm -100 mm) pipe- spigot sell <br />to -fittings.

Pipe -to -Couplings <br />When combined with <br />the adhesive, the me- <br />chanical locking action <br />promotes positive make <br />up of the joint and <br />prevents backout during <br />adhesive curing. <br />Pipe is supplied with T.A.B. spigot x T.A.B. spigot ends. <br />Fittings are manufactured to accept either a tapered spigot <br />or IA. B. spigot end of the pipe. Tapers can be made in the <br />field with tools designed for this purpose (seepage 4). Bells <br />cannot be field made. When a belled end is needed, use a <br />sleeve coupling. <br />1707,L <br />While handling, storing, and transporting the pipe, it <br />sometimes incurs rough treatment. Therefore, inspect <br />all pipe surfaces for possible damage to the pipe wall <br />and spigot ends. Inspect fittings for signs of damage. <br />Damaged pipe must be cut out and replaced. Damaged <br />fittings must not be used. If in doubt about damage, <br />contact your local FGS Smith Fibercast distributor or <br />representative. <br />Exposing machined surfaces to direct sunlight will result <br />in loss of joint bonding strength. Because the degree of <br />weathering, surface degradation, and subsequent effect <br />on bond strength varies greatly, depending on geographic <br />location and related factors such as cloud cover, seasonal <br />hours of daylight, intensity of sunlight, humidity, etc., it is <br />difficult to place a fixed time limit on the acceptable amount <br />of exposure. Cover exposed areas L/ <br />of pipe and fittings to protect from <br />UV damage. In all instances <br />where protective coverings are <br />removed from machined surfaces <br />and ultraviolet exposure exceeds <br />one day, corrective action must be <br />taken. <br />Layout <br />Advance planning of the piping layout can reduce the <br />quantities of material required and will make servicing the <br />system easier. NOTE: The scarfed containment pipe <br />must be positioned over the product pipe before bonding <br />the product pipe. <br />Installation Crew Size and Organization <br />Each installation is different and requirements change <br />depending on Metherthe installation is simple (long, straight <br />runs of piping) or complex. Requirements are also affected <br />by pipe size, installation temperature, and similar influences. <br />See Table 2. <br />TABLE 2.
