The 50,000ft 2 extension will allow both an increased stock range and additional machining capacity.

of pipe and a wider range of items, including forged fittings and olets with both standard and special connections, machined from the company’s large stocks of semi-finished forgings, with a very quick delivery time. DK Jones already has in-house capability to machine the faces and bores of flanges with pressure rating up to 2500# and butt weld fittings with wall thickness of up to Sch 160 and XXS in all sizes up to 24" NB. The company believes that the increased warehouse capacity and new equipment will enable customers worldwide to benefit from shorter delivery times for all high quality standard and special fittings and flanges.

Plastic transition fitting with metal thread Georg Fischer Piping Systems has introduced a new transition fitting made of plastic with internal and external threads of metal. On the plastic side, the combined socket and spigot versions provide installers with flexibility. In frosting and defrosting processes, refrigerating plants are subjected to temperature fluctuations that can cause the material to expand. technology provides an extra dose of safety in industrial installations. Available in ABS and PVC-U, and in a variety of dimensions, GF Piping Systems has created a safe and reliable bridge from plastic to metal pipes.

The innovative jointing technology of O-ring and retaining ring compensates for this, while also preventing the connection from coming loose when there is vibration – essential in pipe systems with pumps. Retightening after installation is not necessary. The wide seat of the metal part enables secure mounting of the fitting with conventional installation tools.

The transition fitting is sealed with an EPDM O-ring, which also protects against distortion and damage to the plastic during installation. Additional features of this fitting are its long service life and leak tightness even under temperature fluctuations and vibration. The new fitting, made of plastic and metal, was originally developed for industrial refrigeration technology.

The joints are available in the dimensions d20, d25 and d32 (socket) on the plastic side, and in ½", ¾" and 1" Rp and R threads on the metal side (stainless steel and brass). The pressure rating is PN16 for PVC-U and PN10 for ABS. Georg Fischer Piping Systems Ltd – Switzerland www.piping.georgfischer.com
