摘要： In an implementation, a hydraulic assembly comprising an end section of a hydraulic hose formed from a volume of material, the end section having a first outer diameter and an open end, is formed by molding a flange in the end section of the hydraulic hose, and threading an annular gasket onto the end section of the hydraulic hose between the flange and the open end of the hydraulic hose, and adjacent to the flange. The flange is formed in the volume of material, and has a second outer diameter greater than the first outer diameter. The molding of the flange may include applying heat to a mold, inserting the open end of the end section of the hydraulic hose into the mold, and thermally deforming a portion of the end section of the hydraulic hose to form the flange.

摘要： A hydraulic tube expander includes expanding jaws engageable with an interior surface of a tube to expand the tube; a source of hydraulic fluid, a valve located between the source and the expanding jaws and a single-action release actuator operatively coupled to the valve. The valve is moveable between open and closed positions. In the closed position, hydraulic fluid can pass from the source to the expanding jaws and in the open position the hydraulic fluid can pass from the expanding jaws to the source. The actuator is movable between first and second positions. In the first position the valve is in the closed position. Movement of the actuator in a direction from the first position toward the second position moves the valve into the open position.

摘要： A pipe bell-end ring flare device for use with a mandrel to form bell ends with a flared outer edge in plastic pipe sections either as part of the pipe manufacturing process or subsequent to the manufacturing process. The flared edge creating a wider bell end opening to make it easier to insert a non-bell end of another pipe into the flared bell end.

摘要： An expansion toolhead configured to enable the expansion of multiple different sized diameters of cross-linked polyethylene (PEX) tubing with a single expansion toolhead. The expansion toolhead including a cap operably coupled to an expansion tool, and a plurality of jaws forming a 360 degree jaw section operably coupled to the cap, each of the plurality of jaws including an expansion tool interface portion forming a conical recess enabling a cone-shaped wedge of the expansion tool to move the jaw section between an unexpanded position and an expanded position, and a PEX tubing interface portion having a distal end, a proximal end and a plurality of lands positioned therebetween configured to form a corresponding plurality of substantially uniform diameter portions of the jaw section sequentially increasing in diameter between the distal end and the proximal end for the expansion of multiple different standard sized diameters of VEX tubing.

摘要： A polymer pipe has a length between a first end and a second end. The length and the first end have a first diameter and the second end is a belled end having a second diameter larger than the first diameter. An insert device is received or pre-installed within the second end and has an annular body with a seal part coupled to the annular body and a spline groove formed in the annular body and facing radially inward. Another polymer pipe is inserted in the belled end to form a pipe joint assembly and has a mating spline groove on the outer surface. The spline groove and mating spline groove axially align and receive a spline therein to axially interlock the two polymer pipes to form a pipe joint assembly.

摘要： A pipe coupling for triple wall corrugated plastic pipe includes a triple wall corrugated bellmouth connector that is of a unitary construction with one end of the corrugated plastic pipe. This bellmouth connector is of higher strength and in cooperation with the two wall corrugated spigot provides a high strength coupling. This coupling includes the bellmouth connector and spigot that are made inline with the corrugated pipe. A method for the manufacture of the pipe includes controlling of an air pressure on the outside of a formed two wall corrugated pipe as an exterior third wall is secured thereto.

摘要： A filler tube, which is capable of satisfying required functions suitably in compliance with the bellows and non-bellows cylindrical base while securing weld strength and fuel-permeation resistance property in the weld face, is provided. A filler tube includes a non-bellows cylindrical base with a total thickness of from 2 to 4 mm, a bellows with a total thickness of from 0.5 to 3 mm, and a flange having a total thickness of from 3.5 to 5 mm, and including an end face to be welded to a fuel tank. The non-bellows cylindrical base, the bellows, and the flange include inner layers formed so as to have a thickness accounting for from 40 to 60% of the total thicknesses, and formed of high-density polyethylene (or HDPE) serving as the major constituent, intermediate layers exhibiting fuel-permeation resistance property, and outer layers protecting the intermediate layers.
