This utility model discloses a hydrophobic self-cleaning PPR pipe, relating to the field of pipe technology. It includes a hydrophobic guiding layer and a flow guiding layer connected sequentially from the inside out. A porous water-absorbing buffer layer is provided between the hydrophobic guiding layer and the flow guiding layer. Several flow guiding grooves are provided along the pipe axis on the surface of the flow guiding layer. The surface of the hydrophobic guiding layer is coated with a nano-layer, and several lotus leaf-shaped nipple structures are formed on the surface of the nano-layer. Spherical water droplets form point contact with the lotus leaf-shaped nipple structures, which can conveniently and quickly handle condensate generated inside the pipe, ensuring normal pipe operation, extending service life, and ensuring the safety and stability of media transportation.

The utility model relates to the technical field of petroleum processing, and discloses an oil pipe anti-drag pup joint structure which comprises a first pup joint and a second pup joint, as a preferable technical scheme of the utility model, the opposite ends of the first pup joint and the second pup joint are connected with each other, and the first pup joint is connected with the second pup joint. The back ends of the first short section and the second short section are fixedly connected with an oil pipe front end and an oil pipe rear end respectively, an upper rocker arm and a lower rocker arm are arranged outside the first short section, and one end, close to the second short section, of each rocker arm is provided with the end of the first short section and fixedly connected with a hinge piece. Due to the arrangement of the rocker arm, the movable sleeve can be conveniently moved to the front end of the second short section by a worker under the matching of the rotating shaft and the hinging piece, and the movable sleeve can be sleeved on the second short section when the first short section and the second short section are not coaxial, so that the first short section can be dragged to be slowly close to the second short section by rotating the movable sleeve; and finally, the effect that the first short section and the second short section can be conveniently and quickly butted by a worker can be achieved.
