NOTES
*1   The stated information has been defined for conditions according to ISO 1110.
*2 Tensile strengths, fatigue strength (under reversed bending stress) and impact bending
toughness rise constantly at decreasing temperature level, the breaking elongation normally
decreases at a decreasing temperature level.
The above stated information is shown without any obligation and does not release you from own
test arrangements. Tightening Torques and Maximum Loads need to be considered
 
METAL PARTS
Unless otherwise stated, all metal parts are made of carbon steel St37, surface finish according to order code.
 
Surface Finish
In addition to the standard surface finishes stated several alternative finishes are also available on request.
The W3 surface finish is Chromium (IV) free, and is ROHS compliant.
 
Stainless Steel Metal Parts
All metal parts are also available from stock in two different stainless steel qualities:
  • Stainless Steel (W4) A2 - 1.4301/1.4305 (AISI 304/303)
  • Stainless Steel (W5) A4 - 1.4401/1.4571 (AISI 316/316Ti)
Threads
All threaded parts are available with UNC and metric threads

BASIC MOUNTING INSTRUCTIONS 12S
Pipe bends should be supported by STAUFF
clamps as near to the bends as possible.
Furthermore, it is recommended to design
these clamps as fixed point clamps.
The first clamp should be placed directly
behind the threaded connection or coupling.
This protects the threaded connection or
coupling from vibrations.
If valves are incorporated in the pipelines, it
is recommended that support is provided in
front of and behind these valves

Tightening Torques And Maximum Loads In Pipe Direction
All tightening torques and maximum loads in pipe direction refer to clamps with
cover plates and hexagon head bolts acc. to DIN EN ISO 4014/4017 (DIN 931/933).
The max. load in pipe direction (according to DIN 3015, part 10) is an average value,
determined by three tests at 23° C with a steel pipe according to DIN 2448, St 37
– rolled surface – taking static friction into consideration.
Sliding starts when the shown values (F) are reached.
