Joint venture success for heated process pipework
A joint venture operation between two UK companies - Norward Process, which specialises in the production of high purity process pipework, and heating solutions provider Inditherm Industrial - has led to the production of quality heated pipework systems.
The Norward Process pipework products can now be fitted with Inditherm Conductive Polymer Technology (CPT) heating. This carbon-based flexible polymer generates uniform heat over the entire surface area. This includes up to the cut edges, eliminating both cold spots and localised overheating. The heat is generated via a low voltage supply that is both safe and efficient, while providing maximum economy of operation for plant operators.
The flexible heating mat can be wrapped around pipework as well as cut to shape for use on associated equipment such as valves or pumps. It is held in position with insulation that itself is banded on the outside.
However, where required for use in hygienic conditions subject to water-jet cleaning, insulated heated pipework can alternatively be clad with an outer metal sheath. This is high grade stainless steel, without seams or rivets, produced to standards that complement the Norward purity pipework. Ends are capped with stainless steel, with hygienic end fittings used to interconnect between pipework while maintaining integrity of the inner pipework joint seals, as well as providing an external seal against water/dirt ingress.
External links are also used at the joints for the low voltage power supply, so retaining continuity of the heating process.
The Inditherm CPT heating systems can be used to replace traditional technologies of jacketed hot water or electrical trace heating. It provides temperature control to ±1°C, ideal for a multitude of process industry requirements from basic frost protection to product melt-out. Heating management is achieved via either fixed or variable control systems including temperature monitoring and low temperature warning systems.
More sophisticated centralised control systems can also be supplied incorporating PLC's and 4-20mA outputs, with full monitoring touch screen technology featuring both the display and control of temperature, also available.
The high purity process pipework is manufactured using automated orbital welding techniques, with optional internal surface treatments including passivation and electro polishing. Finished products conform to ASME BPE 2000 specifications, and also comply with MCA and FDA standards.
