Corrosion is nature's most destructive element.
One Team high quality insulation products should be used to control and help eliminate electrolytic corrosion.
Flange insulation kits are used for all types of piping and pipeline systems to isolate and prevent the flow of electric currents through a fluid or pipe system.
A key benefit is to prevent damage caused by “electrolysis” and the hazard of static electrical build up.
Assureaseal SSC
- 350 Max Temp (F)
- 800 Dielectric Strength
SSC provides exceptional insulating and sealing performance in aggressive applications.
SSC seal retainer is made from G10 permanently bonded to both sides of a high-strength 316 stainless steel core.
PTFE spring-energized face seal requires far less bolt stress to seal than any other gasket
Assureaseal HT
- 356 Max Temp (F)
- 760 Dielectric Strength
Seal retainer is constructed from NEMA grade G-11 glass-reinforced epoxy. This material has excellent performance characteristics with very high compressive strength, high flexural strength, high dielectric strength and low fluid absorption.

Increase temperature over G10
Warrior G10
- 284 Max Temp (F)
- 800 Dielectric Strength
Seal retainer is constructed from NEMA grade G-10 glass-reinforced epoxy.
This material has excellent performance characteristics with very high compressive strength, high flexural strength, high dielectric strength and low fluid absorption.
Phenolic Neoprene
- 175 Max Temp (F)
- 500 Dielectric Strength
Neoprene faced phenolic gaskets have long been used as a standard insulating gasket in the gas and oil industries because the soft neoprene rubber provides good sealing qualities.
In these gaskets, neoprene sheets are factory bonded to both sides of a laminate phenolic sheet to give good sealing qualities and high electrical resistance.
Phenolic
- 225 Max Temp (F)
- 500 Dielectric Strength
Phenolic gaskets are manufactured from laminated phenolic material, which provide insulation between the flange faces.
It is difficult to obtain an effective seal unless standard 1/16" service gaskets are used with them.
Gasket Type F (Ring)
Type F will fit only the raised face surface of the flanges. The outside diameter of the gasket is slightly less than the inside diameter of the bolt circle.
It is recommended that the flanges are wrapped with Flange Band Protectors to prevent foreign material from collecting and creating a bridge, thus shorting out the isolation.
Gasket Type E (Full Face)
Type E is a full face gasket with the same OD as the flange .
Prevents foreign material from collecting and creating a bridge, thus shorting the cathodic isolation.
Gasket Type D (RTJ)
Type D gaskets are designed to fit into the ring groove of RTJ.
We also offer BX gaskets. Both are available in grade CR phenolic.
Washer Single
Single washer sets may be used to allow the Catholic Protection current to reach the nuts and bolts.
Nuts on the opposite side of the cathodically protected flange may be included.
Washer Double
Double washer sets may be used for added protection, double washers sets also electrically isolates the nuts and and bolts from both flanges.
Washer and Sleeve (One Part)
Easy to install one piece sleeves also allow the inspector a visual indication of sleeve usage.
DO NOT USE in high pressure or large flanges
Washers

Caps
The Step-KO Products easy to use polyethylene snap-on caps offer a maximum protection from rust on both the bolt and nut. The model 1 vertical snap section fits under the nut and creates the perfect press fit of sealing lip and snap cap over the bolt and nut connection where minimum threads are exposed.
In applications where the bolt has at least ½” of exposed thread the Model “S” threads itself to the connection giving the joint protection from the elements that cause corrosion.
Anode cap
Anode cap is Heat Shrinkable Cap, used to seal and protect the critical connection between the lead wire and anode.
It provides stress relief, moisture proofing and electrical insulation at the lead wire exit point. It is the ideal solution to the problem of premature system failure due to corrosion causing lead wire to come out of the anode.
It is made from a highly Cross-linked Polyolefin material. Rubber based mastic coating inside the cap adheres to Anode material and wire insulation which provides water tight sealing according to IP 68 (Ingress Protection)
Pipe Supports & Protection
One Team keeps a wide variety of sizes of AssureaKote™ u-bolts in stock for immediate shipment in standardized box quantities. All the AssureaKote™ U-Bolts in sizes 24” and below are packaged in a strong durable poly bag with the u-bolt, 4 nuts and rubber pad for easy application in the field eliminating the removal of the nuts from the u-bolt before applying to the piping therefore eliminating unneeded labor time. When the AssureaKote™ is coupled with the AssureaPad™, a special blended thermal plastic half round or round pad, you can reduce the possibility of crevice corrosion or water formation under the pipe therefore giving the secure feeling that your piping is protected.
AssureaKote™ coating technology is a special proprietary coating that has superior temperature and physical properties when applied to various types of u-bolts. The AssureaKote™ coating provides excellent protection from corrosion by preventing metal to metal contact between the u-bolt and piping. The AssureaKote™ coated u-bolt is very versatile and can be used in many industries including but not limited to pipelines, refineries, chemical plants, offshore platform, rigs, paper mills, and in marine applications.
Pipe Supports
Titan Pipe Supports are designed to protect pipelines from corrosion. The pipe supports keep your pipeline off the ground and away from potential harmful, foreign substances. These supports also distribute pipeline weight evenly, ensuring that your pipeline can continue to run for years to come.
Sleeper Guard
The Problem Metal to metal contact between a pipeline and its support can cause corrosion that will reduce the strength and lifetime of your pipeline. Water can also build up between the pipeline and its support speeding up the corrosion process. pipeline guard Sleeper Guard Offers With Step-Ko’s Pipeline Sleeper Guards you can eliminate metal-to-metal contact, moisture penetration, condensation cavities, and crevice corrosion. Step Ko’s Sleeper Guards are also extremely easy to install because of its peel and stick pads. Inexpensive, Long-Lasting, Corrosion Prevention Solutions
Shrinkable Pipe Wraps
SHAIC HS-340 is a heat-shrinkable wraparound sleeve designed for corrosion protection of field-welded joints of plastic coated steel pipelines. It has a thick cross linked polyethylene backing coated with butyl rubber based mastic sealant or hot melt adhesive. Hot Melt or Mastic shall depend on project requirements. When heated the backing layer shrinks and the sealant flows and forms a reliable corrosion protection seal onto metal and adjacent coating surfaces. Cut Sleeve is normally supplied with separate Patch Closure, which is coated with a high shear-strength adhesive; however, there are different types and sizes to comply with individual requirements. It is supplied in bulk rolls as well, and has super-heavy duty, heavy duty and regular thickness.
Tank Moisture Seal
Moisture Seal utilizes the combination of the SK2400 gel filler and the seal capabilities of the SM-65A fabric tape to form a moisture barrier between the concrete ring and steel ring interface. The chime seal tape is gray in color and is U/V resistant. The seal provides excellent adhesion characteristics to both the steel and concrete surfaces.
Pipe Backfill Protection
AssureaGuard has been specially designed to protect pipe coatings from chipping during backfill operations.
AssureaGuard is made in Austin Texas with the highest quality standards for the pipeline construction industry. Custom cut sheets are also available for easy installations.
