type SST
(Tapping Sleeves)
Stainless steel tapping tee type SST
stainless steel tapping tee type SST are used for permanent (hot) taps on several pipe types.
for water, gas and petrochemical fluids
Application
The type SST is in fact a reinforced double band clamp with a flanged outlet. The standard working range is 20mm. The standard working range is 20mm.
The clamps can be used to repair the following pipe types:
- Cast iron (DI / CI)
- Steel (St.)
- Asbestos Cement (AC)
- PE coated steel
- PE*
- PVC*
- GRP*
Available sizes:
Tapping tee clamps type SST are available for pipe diameters from DN 80 up to DN 800. Standard length: 500 mm. Besides our standard program, we are able to manufacture any range or length that you may require.
Flange design:
Flanges are drilled acc. to DIN 2576 and NEN 1092-1. The flange thickness is 24 mm for flanges up to DN 200 and 26 mm for flanges up to up to DN 300. Standard flanges are flat faced PN 10, but raised faced, ASA and PN 16 flanges are available upon request.
Depending on OD and flange size the branch can be supported by an additional reinforcement. Pipe and valve should always be supported according to standard codes of practice.
Size on size tapping sleeves require the use of an undersized shell cutter. Please ask your distributor for more information.
Pressure ratings (for water):
Pressure ratings depend on the type of pipe, branch OD, medium etc. In general, type SST tapping tees are for use on pipes up to and including DN 600 mm and can resist a pressure of 16 bar.
Material specification:
- All metal parts: stainless steel AISI 304 or AISI 316L.
- Metal parts have been deburred and are passivated to restore the corrosion resistance to its original state after the welding process.
- Double band (two sections). For detailed working ranges please see our price-list.
- Standard certified rubber gaskets EPDM or NBR. The rubber is tapered and has a waffle pattern.
- Seamless rubber lining for every clamp diameter.
- Bridge plates are vulcanized into the rubber gasket.
- U-shaped lifter bar.
- Stainless steel, electrolytic zinc plated nuts, to prevent fretting.
- Stainless steel washers.
- No loose parts that may get lost during installation.
- No special tools required: a simple wrench will do the job.
- Special tape is used to fix the rubber gasket to the stainless steel band. Special tape is used to fix the rubber gasket to the stainless steel band. This tape is flexible and reinforced with glassfibre thread to withstand hot and humid conditions and guarantee a long storage capability.
- The type SST tapping sleeve is designed for under pressure drilling (hot taps).
