发明名称 An electrofusion fitting
摘要 <p>An electrofusion fitting 10 for a plastics pipeline 11a, comprising: a moulded plastic body having an exterior surface and an interior fusion surface; and an electrofusion element 15 occupying an area at or near the fusion surface, said electrofusion element being adapted to form a fused joint between said fitting and said plastic pipeline,characterised in that: said exterior surface includes a substantially plain-profiled indicator region 18a, 18b located above said EF element area. The indicator region is preferably bounded by a variation in profile 20 on the surface of the fitting, such as flanges, or raised edges, on either side of the indicator region. The indicator region acts as a guiding means for the accurate location of a non-destructive examination tool 30 such as ultrasonic or microwave tools. Engagement means which may have an area of high coefficient of friction and / or a plurality of teeth are preferably provided for engaging the tool. A non-destructive examination tool for inspecting an electrofusion fitting is further provided, the tool having an engaging end 31 for engaging the fitting at the indicator region. At least one reference point for use in inspection may be provided. A non-destructive assessment method for an electro-fusion joint is also provided.</p>
