Applies to all applications: laminated and unlaminated sponges

R
Inspect Safe-T-Sponges® before, during and after use; worn, frayed or damaged sponge should be accounted for and replaced.
R
Protect all sponges from conditions where welding slag, grinding sparks, flame and ignition sources exist.  Laminated sponges are recommended with protection (noted above) where those conditions are encountered.
R
Maximum recommended temperatures are 185°F/80°C for PL/NPL-1 through PL/N-PL-4. Recommended temps are 212°F/100°C for PL/L-PL-5 and larger. High Temperature “HT” sponges have higher temperature ratings; contact factory for details and availability
R
Do not use sponges where sharp edges or surfaces could damage the sponge material.  LE (Laminated Enclosed) sponges may be considered for these applications.
R
Do not contact with acetone and alcohol based solvents as they can damage the sponge material and weaken the laminate bond on laminated sponges.
R
Do not expose laminated sponges to hydraulic and other oils; the laminate bond may be damaged.  Incidental amounts of water based cutting fluids are acceptable.
R
Do not immerse sponges in fluids or expose to continuous amounts of water as this can decrease product effectiveness.  Isolated exposure to small amounts of water is acceptable
R
Cutting or modifying sponges is not recommended.  “Specials” are quickly available from the factory  to prints and drawings
R
Attach lanyards to Safe-T-Sponges® consistent with industry standards.  A tether connecting each handle is required for vertical down applications.
R
Do not step on sponges
R
Vacuuming debris prior to retraction of Safe-T-Sponges® is recommended.

Part # Guide

PL – Base Safe-T-Sponge®
N-PL – Nuclear Specific – small diameter (N-PL 1 – 4)
L-PL – Laminated (L-PL-5 and larger)
(Note: All PL 1-4 and NPL 1-4 are laminated)
LE – Laminate Enclosed
HT – High Temp
ADV and PL 100 and higher- Special Designs

Small Diameter Safe-T-Sponges
PL-1 through PL-4, N-PL-1 through N-PL-4

R
Place the sponge in the tube or opening with the laminate side and the coated loop tip facing up.
R
Many sizes of sponges are available; use a size that is tight but allows for easy insertion and retraction
R
The pull loop is adjustable; place below any machining or milling tools to be used afterward. Loops should be centered for easy extraction
R
Batch control codes are attached to each bag (N-PL sponges only)
R
Tracking sponges is important to insure correct use, retrieval and inventory control.  A manual inventory control system is recommended. Self stick labels are enclosed. RFID implanted sponges are available – contact factory for information.
R
The PL-1 through PL-4 loop tips contain x-ray visible materials to help find parts inadvertently left in boiler tubes. Insert sponges correctly to utilize this feature.
R
Lanyards should be attached to all N-PL sponges consistent with industry standards, where practical this is recommended for PL sponges also.

Large Diameter Safe-T-Sponges

PL/L-PL-5 and larger

R
Insure at least 3/8” (9.5 mm) squeeze on all sides
R
Insert L-PL sponges with laminate side facing up toward the opening.
R
Lanyards should be attached to all sponges consistent with industry standards for nuclear applications and are recommended where practical for fossil and industrial applications.

Custom/Special Safe-T-Sponges specials made from customer supplied specs

R
Sponges are made to customer supplied specifications for unusual openings or applications
R
We assign a unique part number that corresponds to that application
R
Locate the correct opening before use – note correct orientation.
R
Safe-T-Sponges® are designed to “squeeze” and maintain a firm fit.
R
Special lead and design time may be required. Contact factory for details.

Perfect Purge Safe-T-Sponge ®

Our Perfect Purge Safe-T-Sponges® are fast, affordable & reusable. Our purge dams allow enough airflow to prevent blowback at the weld.

Cleaner welds =Lower FM risks

  • “Sugaring” can lead to a weaker weld and QC failure
  • Creates more debris when cleaning up the weld root

How it Works?

R
Insert purge dam and a standard laminated Safe-T-Sponge on either side of weld
R
Attach purge gas cylinder to fitting in order
to replace atmospheric contamination
R
Complete weld and remove once
cooled
