Plugs to be machined from Hex. Bar Stock of SAE C1018 Steel. Pack harden plugs, followed by drawing at a temperature which will relieve the plugs of brittleness and still leave them hard enough to thread themselves into the wall of steel pipe.

Pipe Repair Clamps for temporary repair of pipes
For 1" pipe to 12" pipe, 2 bolt or 4 bolt

Notes
1.  Emergency pipe clamps are intended for temporary repair of failed pipe.
2.  Bar Material shall meet ASTM A-7 specifications.
3.  All clamps up to 4" nominal pipe size inclusive, shall have two bolts, as shown; all clamps over 4" nominal pipe size shall have four bolts. Unless otherwise specified on the order, the supplier shall furnish all clamps completely assembled with nuts and bolts.
4.  Bolts and nuts shall be of commercial quality. Bolts shall have square heads and meet ASTM A 306 class 50, 55 or 60.
Nuts shall be A.S.A. Heavy Series, semi-finished, machined from bar stock are not acceptable. All threading shall conform to the A.S.A. (National) Coarse Thread Series, class 3 fit.

Thermometers

:
Stem Lengths: 2 1/2", 4", 6", 9", 12", 15", 18" and 24" (available up to 120")
Stem Diameter:
.250" standard up to 42" stem.
.375" standard over 42" stem.
Connection: 1/2" NPT.
External Reset: Easy to calibrate by inserting 1/16" Allen wrench into reset opening.
Construction:
304 stainless steel external parts. Welded construction.
Corrosion resistant to most chemicals.
Hermetic seal: Per ASME B40.3 dustproof and leakproof.
Harness:
All stainless steel brackets with screws that loosen to allow 360°
rotation of head and 180° adjustment of stem position.
Bellows:


Heavy-duty flexible stainless steel. Hermetically sealed at case and
connection. Protects mechanism that transfers temperature change
from bimetal coil to pointer.
Dial:

True Anti-Parallax dial, easy-to-read from any angle, minimizes
reading errors. Anodized aluminum with large black numbers and
graduations.
Lens: Glass.
Bimetal Coil:
Helix coil is silicone coated on ranges below 500°F for vibration
dampening and to maximize heat transfer and response time.
Accuracy:
+/-1% full span per ASME B40.3 Grade A. Adjustment of the angle
between case and stem may affect accuracy up to 0.5% of span
(ASME B40.3).
Over Temperature Limits: Up to 250°F 100%; 250°F to 550°F, 50%; 550°F to 1000°F,
continuous use up to 800°F, intermittent use over 800°F.
