The ServiFlex® Insertion Technique (SIT) quickly and easily allows the user to reline 1”, 1 ¼” or 2” metallic service pipes with ServiFlex® back to the meter position.
ServiFlex® is the brand name of Radius System’s twin-walled corrugated flexible polyethylene pipe that is used to reline metallic services and goes around tight radius 90 degree bends. ServiFlex® Insertion Technique (SIT) is the installation equipment that inserts ServiFlex® pipe safely, effectively and efficiently while maintaining its structural integrity to give it up to 50 years of use.
Synthotech’s SIT-3 (ServiFlex® Insertion Technique 3) is approved for use on SGN, Cadent and Wales & West Utilities gas networks. It is 50% quicker than it’s predecessor SITT (ServiFlex® Insertion Technique Two). SIT-3 is cheaper and much simpler and doesn’t use the tension gun that was used in SITT.
Synthotech’s system is the only kit that has been proven to allow PE pipe to be inserted around up to two short radius bends without affecting the ServiFlex®’s integrity. This eliminates unnecessary excavations and external meter re-runs, saving considerable operational time and cost.Â
SIT-3 is a two-person operation and can be used for both construction and repair and maintenance activities so can be used whenever required.
Key benefits include:
- Avoids the costs associated with gas meter re-runs (typically ÂŁ150-ÂŁ300).
- Significantly reduces excavation reinstatement and associated activities.
- Maximises capacity through-put around short radius bends.
- Significantly reduces the cost of pipe replacement on registered and/or listed buildings.
- Reduces the time consumers are without gas.
- Reduces operational cost.Â
