Abstract
A fiberglass pipe joint with threaded ends has rough surface areas adjacent to such ends which allow strap wrenches to be used to tighten the threads with a high torque that prevents leakage. The rough areas are formed by partially embedded sand grains which are sprinkled on the resin component prior to curing, or on a wet bonding material after curing.
