E3 <br />AMERICAN Fastite° Joint Pipe <br />For Water, Sewage or Other Liquids <br />AMERICAN Fastite Joint Pipe in sizes 4"- <br />64" for water, sewage or other liquids has the <br />proven long -life and high -strength qualities <br />inherent in pipe produced centrifugally in <br />accordance with AWWA C151. In addition, <br />this significant AMERICAN development, a <br />dependable, single gasket, push -on type joint <br />meeting the requirements of AWWA C111, <br />affords the customer lower joint cost and <br />time -saving advantages in installation. It pro- <br />vides exceptional strength and flexibility and <br />has been widely accepted by engineers, con- <br />tractors and utility officials since the 1950s. For <br />added flexibility during construction, and for <br />possible elimination of bends, a liberal 5° <br />allowable deflection is standard in all sizes <br />through 30", offering 21" offset in a 20' <br />length of pipe. Liberal deflection can also be <br />provided in larger diameter pipe with standard <br />and Special Fastite Deflection Bells. <br />The patented AMERICAN Fastite Joint <br />embodies many advanced design features and <br />is rated for a water working pressure of 350 psi. <br />For specific conditions, ductile iron piping with <br />this joint has been approved for much higher <br />pressure conditions. The socket, which is scien- <br />tifically designed with two gasket recesses and a <br />dividing buttress, is manufactured to close toler- <br />ances so that the gasket is self-centered, securely <br />confined, and firmly compressed for a perma- <br />nent, tight, trouble -free joint. The Fastite joint <br />seal, bubble -tight under vacuum and external <br />pressure, becomes even tighter with the appli- <br />cation of internal pressure due to a specially <br />designed wedging surface in the socket. <br />Fastite Joint Assembly <br />The bell opening is slightly tapered to <br />provide easy entry of the pipe end; the flared <br />socket design permits liberal joint deflection. <br />2-6 <br />The plain end of the pipe is tapered or rounded <br />to facilitate entry into the bell and self -centering <br />in the gasket. On pipe cut in the field, the <br />plain end can be easily beveled and smoothed <br />by the use of a portable grinding wheel or <br />other suitable apparatus. Methods of cutting <br />ductile iron pipe are described in Section 3. <br />A stripe is painted on the plain end of <br />AMERICAN Fastite Joint Pipe to provide a <br />visual means of checking the joint alignment <br />and to assure proper insertion. See page 2-10 <br />for detailed assembly instructions. <br />Fastite Gasket <br />The Fastite Joint sealing component —a <br />molded synthetic rubber ring gasket of two <br />hardnesses, shaped to fit the configuration of <br />the gasket socket —is manufactured per all <br />requirements of ANSI/AWWA C111/A21.11 <br />and under AMERICAN's own rigid specifica- <br />tions, assuring closely controlled dimensional <br />and hardness properties. The smaller end of <br />the gasket is of harder rubber, approximately <br />85 durometer hardness, which provides a <br />strong shoulder for self -centering on the gas- <br />ket buttress, a permanent seal against cold <br />flow, and protection from deterioration. The <br />larger end of the gasket is of softer rubber, <br />approximately 65 durometer hardness, provid- <br />ing ease of assembly and positive sealing. The <br />design assures effective sealing at low or high <br />pressures and in straight or deflected joint <br />alignment. It also eliminates any concerns of <br />infiltration or root intrusion, and assures posi- <br />tive sealing against negative pressure, thus <br />preventing gasket "pullout" should a vacuum <br />be created in the line. <br />A taper on the inside of the gasket allows <br />the entering pipe to locate and center on the <br />hard section and reduces friction loads during <br />
