New SWL machine for electrofusion fittings

image MSA Engineering Systems Limited (UK) has developed a brand new SWL (saddle wire laying) machine for laying wire directly into the curved face of a saddle fitting. The electrofusion fittings used to join thermoplastic pipes as typically used in the gas, water and petrochemical industries.

The machine enables large saddle parts to be produced, typically with outlets up to 280/315mm diameter with an overall part size of 450mm x 450mm, and saddle diameter from 90mm to infinity (standard and special types).

image MSA’s patented wire laying method inserts wire into a moulded fitting or fabricated part in a special CNC process which has many advantages and far greater flexibility than traditional methods. In the case of saddle fittings, this new development eradicates the problems experienced by laying wire into a separate pre-grooved pad, which then has to be inserted into the saddle body mould. It also enables special large fittings to be completely fabricated.

MSA also manufacture a range of horizontal and vertical format CNC systems for the production of couplers from 20 to 1200mm diameter. Elbows, reducers, tees and electrofusion pads can also be made on the same machines. In association, MSA produce a range of innovative electrofusion control units (ECU), including a COMBI-UNIT which combines a generator and ECU in one, convenient, portable unit.

MSA will be exhibiting at K-Show in Düsseldorf. On the stand will be an example of their wire laying equipment and their NEXUS 500-LT lightweight electrofusion control unit.
