A recently granted patent (Publication Number: US11992997B2) discloses a biaxially oriented pipe with a thickened end portion made of the same thermoplastic polymer composition as the pipe itself. The thickened end portion has a larger thickness than the pipe but maintains the same inner diameter. The patent specifies that the thickened end portion must have a minimum ultimate tensile load of at least 80% of the pipe's minimum ultimate tensile load, as per ASTM D2290 standards. The thermoplastic polymer composition can include materials such as polyethylene, polypropylene, polyvinylchloride, and others, with high-density polyethylene or random polypropylene being specifically mentioned.

Furthermore, the patent also covers joined pipes, where two biaxially oriented pipes are connected through a joint portion made of the same thermoplastic polymer composition. The joint portion has a larger thickness than the pipes, and the end portions of the pipes must have a minimum ultimate tensile load of at least 80% of the pipe's minimum ultimate tensile load, as per ASTM D2290 standards. The joined pipes can have outer diameters ranging from 2mm to 2000mm and thicknesses from 0.3mm to 100mm, obtained through specific drawing ratios. This innovation in pipe design and joining processes aims to enhance the structural integrity and performance of pipes in various applications.
