SCITEQ end closures air frame 1525

For internal hydrostatic pressure testing of pipes and fittings. The end closures seal off the sample in order to generate internal pressure in the sample. Max. pressure is 40 bar depending on standard, specifications and pipe sample diameter.

The SCITEQ air frame end closures model 1525 are produced purely in stainless steel. The end closures are used for relatively low pressures up to max. 40 bar in combination with temperatures between 20 to 95 degrees. The weight is considerably lower for large diameter pipes compared to traditional large diameter end closures, yet a robust construction has been maintained. The lower weight and altered construction ensures easy handling when mounting. Further, grips for cranes are incorporated.

End closures without a tie bar are produced for pipes and fittings in PE, PEX, PVC, PP, ABS etc. End closures are produced with a specific depth from O-ring to the internal bottom which ensures that even on chamfered and oval PE-pipes, the end closure is tight while pressurising.
