Caution: If a spigot end contacts the <br />ground or trench side after lubrication, any <br />adhering dirt or rocks should be cleaned off <br />and the area re -lubricated prior to assembly. <br />4. Insert the plain end in the socket. For <br />optimum assembly it is preferable that the <br />entering pipe be in reasonably straight align- <br />ment; however, the Fastite Joint may be <br />assembled if necessary with the pipe deflect- <br />ed within its rated deflection. (Exception: If <br />Fast -Grip gaskets are being used, straight <br />alignment must be maintained.) Push the <br />plain end into the socket using any of the <br />applicable assembly methods described <br />hereinafter. If the joint cannot be assembled <br />with a moderate force, remove the pipe and <br />check for the cause of the difficulty, such as <br />improper positioning of gasket, insufficient <br />or wrong type lubricant, dirt under or behind <br />the gasket, dirt adhering to the pipe, or any <br />other cause which would result in obstruc- <br />tion or increased friction between pipe end <br />and gasket surface. For assurance of proper <br />assembly, a thin automotive, blade -type <br />feeler gauge can also be used if desired for <br />quick and easy probe confirmation of cor- <br />rectly installed axial gasket position around <br />the joint. <br />5. "Backwards" installation. AMERICAN <br />does not recommend "backward laying" <br />(bells assembled over spigots, rather than <br />spigots inserted into bells as pictured in this <br />literature) of large -diameter ductile iron pipe <br />in buried installations. AMERICAN can furnish <br />bell and plain end fittings to minimize the <br />need for backward pipe laying. Other <br />devices such as sleeves and couplings may <br />also be employed for this reason. However, <br />if this condition cannot be avoided, we <br />strongly recommend that installers contact <br />AMERICAN for instructions on how to reduce <br />the potential for problems that could occur <br />when assembling pipe in this manner. <br />AMERICAN Pipe Assembly Mechanisms <br />In general, Fastite joints or other Fastite <br />gasketed pipes may be readily pushed or <br />pulled together without the need for com- <br />plicated tools or substantial manpower. This <br />is most often accomplished with the proce- <br />dures discussed on page 2-14. In general, <br />the joints of AMERICAN push -on pipes are <br />purposefully "tight," and most joints require <br />an assembly force of about 100 to 200 <br />pounds or more of assembly force per inch <br />of pipe diameter (i.e. a 12" joint might <br />require about 12 x 100 or 1,200 pounds of <br />assembly force). <br />In pulling operations, simply wrap a <br />sound wire rope choker cable or nylon sling <br />around the barrel of the entering pipe. <br />Secure the thimble eye or other end loop of <br />the choker to a suitably anchored pulling <br />device (e.g. backhoe, come -along, etc.). <br />Use the mechanism to pull the cable taut in <br />Photo 3 <br />the assembly direction (Photo 3). Continue <br />pulling the cable in a smooth, continuous <br />motion until the joint is in the fully assembled <br />position. If desired for special conditions, <br />AMERICAN can furnish suitable, simple <br />come-alongs and choker cables for man- <br />2-11 <br />
