Application Joins and restrains a plain-end Ductile Iron pipe to plain-end Ductile Iron pipe or plain-end Steel pipe to plainend Steel pipe with no other method of restraining pipe required. The soil values in the EBAA program utilize frictional values that were derived from soil box studies performed on surfaces of ductile iron pipe, ductile iron pipe wrapped with polyethylene, and PVC pipe and several different soils. This ring has serrations machined on the inside which lock onto the pipe when the clamping bolts are tightened. Additionally, the valve and stub piece must also be restrained to the tee. In summary, for the case of an equal outlet tee with an adjacent valve on the run pipeline, the required length of restraint for the branch and the “tee side” of the valve should be calculated based on the procedures used for a 90º bend.
