An apparatus and method for re-rounding a distorted end (e.g., oval-shaped) of a pipe for insertion into a mechanical joint fitting or pipe bell have a circular diameter. The apparatus involves two separate semi-circular members having jack bolt assemblies evenly distributed in each. The two ends of each of the semi-circular members have extensions that can be releasably coupled to join to the two members to form a circular re-rounding tool. A first semi-circular member is positioned on the maximum diameter side of the distorted pipe and the other semi-circular member is placed on the opposite side of the distorted pipe and extensions joined. With an equal number of jack bolt assemblies in each member, corresponding jack bolt assemblies in the two members are diametrically aligned forming pairs. To re-round the distorted end, pairs of these jack bolt assemblies are tightened in a “star sequence” to re-round the distorted end. The re-rounded end is inserted into the mechanical joint fitting or pipe bell and the extensions are decoupled to easily remove the circular tool from the re-rounded end.

A downpipe fitting for coupling between top and bottom ends of a downpipe. The downpipe fitting includes two parts connected together and rotatable relative to one another about a longitudinal axis thereof. The first part has an inlet, sized and shaped to couple with an outlet of a first section of the downpipe, above the downpipe fitting. The second part has an outlet which is sized and shaped to couple with an inlet of a second section of the downpipe, below the downpipe fitting. The inlet and outlet of the fitting define a flow path for rainwater therethrough. Rotation of the second section of downpipe below the downpipe fitting, about the longitudinal axis, is decoupled from the first section of downpipe above the downpipe fitting.

A snout apparatus for guiding high pressure flexible lances between a lance drive apparatus and a flexible lance positioner apparatus includes one of a male tubular connector and a female tubular connector fitting adapted to fasten to a flexible lance drive apparatus, another one of a male and a female tubular connector fitting adapted to fasten to a flexible lance positioner, and a plurality of segments connected together in series so as to connect in series between the one and another connector fittings. Each segment may include a cylindrical tube portion sized to receive and pass therethrough flexible lances and a tubular collar portion connected to the tube portion. The collar portion has peripheral arcuate closed slots adjacent to and spaced around a distal end of the collar portion. Shoulder bolt fasteners are each fastened to a next segment tube portion and extend through one of the closed slots.

A fluid injector for connecting a connection port of a container or tank includes a housing and a transmission mechanism disposed in the housing. The housing has a fluid inlet and a fluid outlet surrounded by an annular wall. A control valve is provided in the housing for opening and closing the fluid inlet. One end of the transmission mechanism is connected to the control valve, and another end of the transmission mechanism is connected to a movable post passing through the annular wall. When the control valve opens or closes the fluid inlet, the transmission mechanism is driven by the control valve, and the movable post extends out of the annular wall to be engaged with the connection port or retracts into the annular wall, thereby determining the connection state of the fluid injector and the connection port and ensuring that the movable post is exactly controlled.

A pipe and fitting coupling system includes a first pipe, a second pipe, and a joint. A receiving end of the second pipe includes a first flange, a second flange, a groove, and a sealant. The second flange extends further than the first flange. The groove is disposed at the pipe diameter and between the first flange and the second flange. The first flange has an inwardly angled face to meet the groove and the second flange has an outwardly angled face to meet the groove. The sealant is disposed in the groove to seal the plain end of the first pipe in the receiving end. The joint is formed by the cooperative alignment of the plain end being inserted into the receiving end and being sealed by the sealant.

A pipe/fitting having an end having a modified crimp for securing both flexible ducts and pipes. Specifically, the pipe/fitting includes an end having a series of annularly disposed pipes. The modified crimp includes an outwardly facing channel in the base of the series of crimps configured to secure a flexible duct between the channel and a fastener received in the channel. The end also includes a pipe coupling system at the base of the series of crimps configured to couple a pipe to the conduit.
