An apparatus and method for joining pipes includes a plate for melting mating surfaces of the pipes to be joined. Additionally, the apparatus utilizes a vacuum in order to push the first and second pipes together in lieu of hand or mechanical pressure which may be inconsistent. Additionally, the vacuum allows the pipes to be joined to settle on each other in order to create a pressure about a periphery of the end of the pipe being joined to the other pipe. The consistent pressure creates a very strong joint between the first and second pipes.

A push joint adapter is connectable to one or more push joint pipe fittings in a pipeline. The push joint adapter includes an insertion section insertable into a socket of a push joint pipe fitting in an interference fit, a pipeline section connectable with the pipeline, and a collar disposed between the insertion section and the pipeline section. A restraint ring assembly cooperable with the push joint pipe fitting includes a restraint ring secured to the pipeline section and engaging the collar and a restraint rod connected to the restraint ring. The push joint adapter facilitates connecting push joint gasketed bell gate valves and fittings in a pipeline such as a polyethylene pipeline.

Fluid transfer assemblies for transferring fluid into or out of a single vessel and distributing the fluid to multiple other vessels are provided. The fluid transfer assemblies are customizable, substantially aseptic, and single-use. The fluid transfer assemblies may be manufactured by solidifying polymeric materials to form a body around a mandrel with protrusions engaged to fluid conduits and leaving recesses in the solidified polymeric material to stretch the resultant body and remove the mandrel with protrusions. The resultant fluid transfer assembly may be surrounded by a rigid housing and valves may be engaged with the conduits and/or body to control the fluid flow within the fluid transfer assembly.

A resin pipe joint (1, 11) includes a tubular joint body portion (2, 12) defining an internal flow path (P) the internal flow path being configured to allow a fluid to flow therein; and two or more welding end portions (3-3c, 13a, 13b) respectively provided at two or more opening portions (A1-A3) of the internal flow path (P), each of the welding end portions being configured to be welded to an abutting welding end portion of other resin piping member, wherein the internal flow path (P) comprises: one of a branched point (Bp) that branches the internal flow path (P) into two or more portions; a curved point (Cp) that bends the internal flow path (P); and an internal diameter transition point (Tp) that changes an internal diameter of the internal flow path, in mid-way of the internal flow path, and wherein a length (Lh) from the branched point (Bp), the curved point (Cp) or the inner diameter transition point (Tp) to an end face of the welding end portion (3-3c, 13a, 13b) is shorter than half of a straight distance (SD, SD1-SD4) between two points adjacent to each other, the two points being selected from the group consisting of branched points (Bp), curved points (Cp) and inner diameter transition points (Tp) of piping to be formed using the resin pipe joints (1, 11).
