Penetration Seals are interlocked rubber links that are designed to provide a leak-proof and insulated seal that fills the annular space of pipe penetrations. Penetration Seals fit around piping going through walls, floors, tanks, manholes, vaults, dikes, and pipeline casing to provide a gas and watertight seal. Penetrations Seals have been tested to withstand a hydrostatic seal up to psig or 40 feet of head pressure. Standard construction material of a penetration seal is EPDM rubber which is suitable for most applications. Nitrile rubber seals are available for services of solvents, hydrocarbons, oil, gas, and jet fuel. Silicone seals are available for high temperature applications. Penetration Seals are economical, reusable, easily installed, and available in many sizes to fit nearly every pipe penetration, from 1/2" pipe to 98" pipe.

Nut and Bolt Protectors are plastic nut and bolt protector caps that snap tightly over stud ends and nuts to protect them from the environment and eliminate corrosion. Nut protector are made of polyethylene plastic that is UV and chemical resistant. While nut caps may be used to eliminate excessive paint buildup on bolt threads, the leading benefit is defending the stud bolt threads and hex nuts from rust and corrosion, thus allowing easy unbolting. Nut Caps are economical, reusable, easily installed, and available in all sizes for heavy hex nuts ranging from 1/2" to 3".

For additional corrosion protection, we recommend our flange and nut protection grease - Corrosion Inhibitor Grease - added inside the caps to displace air and moisture and extend service life.  Grease is available in 14oz cartridges and 5 gallon pails. 

For a complete flange protection system, including Drake Specialties Flange Band protectors, in conjunction with Nut/Bolt protectors and grease, is recommended.  The Flange Protectors enclose the flange and internals, providing protection from salt spray, sand, chemicals, and other rust causing external factors.  Click our link here, Flange Band Protectors, for additional details.

Flange Band Protectors are designed to protect flange internals - flange faces, stud bolts, and gaskets - from environmental elements that can cause corrosion. Flange protectors by Drake Specialties are used in the oil and gas industry, refining, gas distribution systems, and any place where it is necessary and desirable to protect flanges and joints from salt spray, chemicals, sand, debris, and other rust causing external factors. 

NOTE:  Flange Protectors do NOT prevent lateral spray-outs, and therefore should not be used as safety devices.  Flange Safety Spray Shields are designed for spray protection and containment; click on the link for more details. 

For a complete flange protection system, we recommend including Drake Specialties Nut/Bolt Protector Caps and Corrosion Inhibitor Grease.  The Nut/Bolt Protector Caps are plastic caps that snap tightly over nuts to protect stud ends and nuts from corrosion. The caps allow for easy unbolting of flanges and valves.  Click our link here, Nut/Bolt Protector Caps, for additional details.

Filling the flange cavity and Nut Caps with non-conductive Corrosion Inhibitor Grease displaces air and moisture to provide extra corrosion protection.  Grease is available in 14oz. cartridges and 5 gallon pails.

Flange Isolation Gasket Kits are designed to maintain the integrity and reliability of the pipeline and piping system through safety and corrosion protection. Flange Isolation Gasket Kits provide an effective seal and electrical isolation of flanges. By eliminating metal to metal to metal contact, static current is halted to prevent corrosion and aid in the cathodic protection of the pipe.

Constructed of high quality materials that have a high dielectric constant and low water absorption, our Flange Isolation Gasket Kits are available for all size flanges, ranging from 1/2" to 144" in all ANSI and API classes In addition, utilizing Flange Band Protectors in conjunction with flange insulation kits further enhances reliability and reduces risk. Drake flange protectors seal the flange internals to prevent foreign objects or debris from lodging between the flanges, forming a bridge, creating a short, and compromising the entire cathodic protection system.

Gasket Kit Types

Type F Gasket Kit Type F "Raised Face" gaskets will fit only on the raised face surface of the flanges. The outside diameter of an F style gasket is slightly less than the inside diameter of the bolt circle. F type gaskets can be used on both raised face and full face flanges. It is recommended that the flanges be wrapped with Flange Band Protectors available from Drake Specialties or a similar device to prevent foreign material from collecting and creating a bridge, thus shorting out the cathodic isolation. Type F gaskets are available in phenolic, neoprene-faced phenolic, and high temperature materials.

Type E Gasket Kit Our Type E "Full Face" Gasket style kit contains a full-face gasket that has the same outside diameter as the flanges. This style of gasket will prevent foreign material from collecting and creating a bridge in the flange which would short out the cathodic isolation. Type E gaskets are available in phenolic, neoprene-faced phenolic, and high temperature materials.

Type O Gasket Kit Type O Gaskets have a sealing element on each side of the gasket and are available in both Type E and Type F styles. The sealing element materials are Nitrile, Viton, or Teflon®. Type O Gaskets are made of both phenolic and G-10 materials.

Type D Gasket Kit Type D gaskets are designed to fit into the ring groove of RTJ (ring type joints) flanges. We also offer BX gaskets. Both are available in grade CE phenolic.

Drake Specialties' comprehensive line of Safety Spray Shields are backed by our industry-leading design of Metal Spray Shields constructed of corrosion resistant 316 stainless steel. Stainless Flange Spray Shields and Stainless Valve Spray Shields for all sizes and ratings of flanges,valves and all other types of piping connections, are readily available.

Although Teflon® Spray Shields are the most popular shield style, 316 stainless steel models excel in highly aggresive and demanding applications, including concentrated chemicals, steam, flammables, high temperatures, and high pressure services.

Two distinct styles of Metal Spray Shields - the well-known version of overlapping tabs design and our new, patent pending, band/mesh/latch style, demonstrate our capabilities.

Our new band-style of Flange Protector Shields feature a stainless steel mesh netting that absorbs and dissipates hazardous sprays by distributing it around the flange circumference, reducing it to a mere visible drip. The tough netting also allows for ventilation, thus limiting corrosion due to complete entrapment of vapors or moisture.

Features of Drake Specialties' Patent-Pending Stainless Spray Shields include:

• Lockable, adjustable, quick latch fastener.
• Installs in seconds.
• No tools required.
• Eliminates splash or mist.
• No sharp edges.
• Complete visibility of bolt ends and nuts.
• Maximum operating temperature of 2000° F.
• Maximum operating pressure of 3000 psi.

Our 2nd most popular style of Metal Spray Shield is the well-known version: the wider, overlapping tabbed edges design that contains spacer rods which allow for spray redistribution.

Beyond doubt, all styles of Spray Shields by Drake Specialties provide safety and protection for personnel, equipment, and the environment.

Safety Spray Shields are designed to prevent and reduce catastrophic damage and injury to workers, property, and equipment by temporarily containing hazardous leaks and sprays. Early leak detection helps reduce maintenance costs in plants by preventing downtime from failures or recordable accidents.  

Recommended and required by OSHA and some insurance companies, Spray Shields are an important factor in risk management and reducing liability concerns in process piping systems.

Most commonly used on flanges in acid and caustic chemical services, Flange Protectors, Flange Guards, and Flange Wraps, as they are sometimes called, are available for valves, unions, or any other type of pipe joint. 

Drake Safety Shields are recommended on connections in these common corrosive and hazardous instances:

• Piping near head and eye level.
• Piping near walkways and traffic areas, including overhead.
• Unloading/loading areas, including docks and terminals.
• Piping on discharge side of pumps.
• Piping in tight, confined spaces.
• Piping conveying flammables near hot surfaces and electronics.

Drake Specialties manufactures a suitable spray shield for every application from materials that are chemical, UV, and weather resistant. From cryogenic service, to high temperatures, Drake has a solution.

Our coated cloth styles come in 8 different fabrics, including four Teflon® Spray Shield styles, two Polyvinyl Chloride PVC Spray Shield styles, one Polyethylene, and one Polypropylene style.

Solid fabric shields are leak indicating shields, and contain a replaceable pH indicating patch which signals a leak by immediately changing color. Our see-thru styles are clear shields, and are preferred by maintenance for visual inspection.

Beyond fabrics, our 2 lines of metal shields are made of corrosion resistant, 316 Stainless Steel.

We offer spray shields for all ANSI, DIN, PN, BS, JIS, AS, and KS standards.
