1. What is butt fusion?
Simply put, butt fusion joints are made by joining two molten pipe ends together under pressure. There are six steps to fusing pipe:
· Secure and clean the pipe
· Face the pipe ends
· Align the pipe profile
· Melt the pipe ends
· Join the two pipes together
· Hold under pressure while the pipe cools
2. Are butt-fused joints as strong as mechanically coupled joints?
Properly made, joints made by butt fusion are stronger and more reliable than mechanically coupled pipe. The joints don't leak and are as strong as, or stronger than, the native.
Our equipment is precision made, but rugged and simple to operate. DSL fusion equipment efficiently produces high quality joints time after time. Higher priced equipment with all the bells and whistles will not produce better joints.
4. How can I determine the quality of a fusion joint?
The Plastics Pipe Institute's website at http://www.plasticpipe.org/pdf/pubs/handbook/inspection.pdf outlines simple procedures, including the Bent Strap test, that help you determine the quality of both fusion joints and your fusion method.
5. How much material should be removed in facing?
Generally one should face to the facer stops on the machine. Removing this much material will help ensure a clean and square fusion face.
6. You make a wide range of butt fusion machines.how do I choose the most suitable one for me?
The critical factors in the selection process are the range of pipe sizes you wish to join, and the dominant pipe diameter. For example, if you intend joining 125mm pipe on a regular basis, it would make sense to opt for a 180mm or 250mm butt fusion machine rather than the 315mm option because of the lighter weight of the chassis. You can always hire butt fusion machines from Fusion Hire and Repair if you occasionally need to join larger pipes outside the range of your existing butt fusion machine.
DN stands for "diametre nominelle". These sizes, in millimeters, are set by the International Standards Organization and are in use throughout the world. They roughly correlate, converting inches to millimeters, with the nominal pipe sizes commonly in use in North America .
8. What is the DSL fusion equipment warranty?
