A pipe end protector for protecting pipe threads provided on a pipe end of a pipe component for exploration and production of a hydrocarbon well, said pipe end protector comprising a main body and an annular flexible lip seal, wherein the main body is made from a first polymeric material having a first elastic modulus, and the lip seal is made from a second polymeric material having a second elastic modulus which is lower than the first elastic modulus.

Pipe end protector

A pipe end protector for protecting pipe threads provided on a female pipe end of a pipe component for exploration and production of a hydrocarbon well, said pipe end protector comprising a main body and an annular flexible axial lip seal, wherein the main body is made from a first polymeric material having a first elastic modulus, and the lip seal is made from a second polymeric material having a second elastic modulus which is lower than the first elastic modulus.

Embodiments of the present disclosure are directed to methods of manufacturing steel tubes that can be used for mining exploration, and rods made by the same. Embodiments of the methods include a quenching of steel tubes from an austenitic temperature prior to a cold drawing, thereby increasing mechanical properties within the steel tube, such as yield strength, impact toughness, hardness, and abrasion resistance. Embodiments of the methods reduce the manufacturing step of quenching and tempering ends of a steel tube to compensate for wall thinning during threading operations. Embodiments of the methods also tighten dimensional tolerances and reduce residual stresses within steel tubes.
