Welded Fittings SPF Welded s are designed and Manufactured to reduce the amount of weld required to install the Tee-Lets on thin wall or proprietary flow pipe. Typically only one weld-pass completes the installation. SPF Welded s install with less weld volume than any other brand of welding outlet fittings for fire sprinkler applications. To accomplish this: The contoured end of the fittings employs a reduced outside diameter. Two major advantages are immediately apparent: The thinner wall on the contoured end permits welding temperatures to be matched to the thickness of the branch line or main thereby insuring complete penetration without cold welds, weld roll-off, burnthrough or excessive distortion. On smaller sizes a heavier section is maintained on the threaded end of the fitting. This protects the threads from damage during shipping and handling prior to installation as well as from weld distortion. Each outlet size 2" and larger, whether female threaded, cut grooved or beveled requires the same hole size in the header pipe. This simplifies the installation process. GENERL SPEIFITIONS Welded outlet fittings are manufactured from highly weldable steel which conforms to the chemical and physical requirements of STM -, Grades or, Type E. Ease of installation is assured when automatic welding equipment is used to install SPF Welded s. Threads are cut in accordance with the requirements of NSI.20., national standard for tapered pipe threads. SPF Welded s threaded and grooved welding outlet fittings are UL/UL Listed and FM pproved for use in the fire sprinkler systems installed in accordance with the requirements of NFP. They are rated for 00 PSI operation in fire sprinkler systems, and higher pressures in other non-critical piping systems. SPF Welded s are offered in a wide variety of header sizes. The consolidated header sizes shown in the following charts allow the fittings to be installed on more than one header size, permitting the first size listed to fit the header perfectly, while a small gap along the longitudinal center line of the header will appear for the second size listed. SPF Welded s are identified by a lot number that provides full traceability.

Welded Fittings Threading Practice SPF Welded s thread form is consistent with eronautical National Form (NPT) S70. The thread is fully formed over both the L- hand tight and L- wrench tight threads. NPT tapered threads are typically gauged only over the L- threads. This makes SPF Welded s more forgiving of field cut threaded pipe that may only marginally conform to the specification. Fewer leaks translate into lower costs. Ease of Installation SPF Welded s are designed to sit higher on the pipe, thereby requiring less weld and eliminating burn through. SPF Welded s sit higher on the header or branch line pipe than competitive fittings. This allows the welding torch to remain in an optimum position for welding. In addition, /2" and larger female threaded and grooved welded outlets require the same hole size for installation. This results in fewer change overs when installed using automatic welders.

This reduces time and savings over time are substantial. The diameter of the contoured end of Welded has been reduced so that the wall thickness more nearly matches the header or branch line pipe wall thickness. Therefore, current and voltage settings required for welding are set to provide for adequate penetration without burn through and cold shutting. lso, weld volume required for installation is lower for SPF Welded s than most other fittings.

Welded Fittings Recommended Installation Procedures SPF Welded Fittings are designed and manufactured to reduce the cost of installation from both the standpoint of labor required and energy consumed. In addition, by following the recommended installation procedures, many of the problems associated with installing welding outlet fittings on standard weight or light weight pipe are eliminated, including burn through and excessive shrinkage resulting in pipe distortion. Recommended Hole s The hole cut in the branch or header pipe can be cut prior or subsequent to attachment of the Welded s. One advantage of cutting the hole after welding is that the pipe is left intact during welding, thereby, reducing shrinkage and possible distortion. If holes are cut prior to welding, as some codes require, then the following hole sizes are recommended. 2, & Recommended Welding Procedures - 2 SPF Welded Fittings are designed to be installed on standard weight or light weight pipe with one weld pass on sizes through 4. Moreover, the wall thickness at the weld end of the fitting approximately matches standard weight pipe. ccordingly, heat settings can be made to optimize penetration on both the fitting and the pipe which it is being welded. side from reducing the likelihood of burn through and distortion resulting from excessive heat, the amount of weld required for adequate penetration is significantly reduced. s a general rule, the weld should be only as hot as required to allow the weld to penetrate the materials being welded while concomitantly allowing gases developed in the welding process to escape. Every effort must be made to avoid welding too hot or overheating both the pipe and the Welded s. Excessive heat may cause the wrench tight threads (those in the bottom of the Welded s near the weld zone) to distort while also causing the branch pipe to bend. It should be noted that SPF Welded Fittings have been subjected to exhaustive testing and evaluation, and only negligibly distort when subjected to excessive heat. The threads, on the other hand, may not return to their gauged form after cooling if excessive heat causes them to expand. The following is intended only as a guide, and assumes that the welding equipment is properly calibrated and functioning normally and the operator is qualified.
