What are Flange Guards & Spray Shields?

Flanges are used for pipe connections. Flange Guards or Flange Spray Shields in simplest terms are pipe flange covers designed to stop mist & spray outs in the event of a flange, valve or any pipe joint failure. Piping system carrying corrosive liquids at high pressure sometimes result failure leading to splash & spray-outs which is very fatal for the worker & equipment around it. Flange Shields & Spray Guards are designed to temporarily contain the spay out and prevents accident by providing Pipe & Flange Spray Protection. Following are the most common Flange Shield & Spray Guard Material Available with Indana

PTFE Flange Guard & Spray Shield:

PTFE Polytetrafluroethylene is a nonflammable fluoropolymer.PTFE is completely inert to chemical attack making it apt for most of the process liquids. Inspite of having properties like low dielectric,non sticky and high thermal resistance PTFE has low mechanical strength which is why Acid Spray shields of pure PTFE is not used. PTFE is coated on to fibreglass fabric which gives the PTFE coated fibreglass flange leak guard high mechanical strength.

PTFE Flange Guards are also known as acid & chemical flange wraps or teflon (TFE) flange guards. Our PTFE flange Guards, pipe spray Shields & Flange shields are manufactured using multiple layers of PTFE with an inner scrim inside. Inner scrim holds on to the flanges and keeps the guard secured. PTFE Flange Spray Guards are stitched by Military Grade Kevlar threads which are known for high strength and thermal stability. Most of the PTFE Flange Guard & Protector Band available in the Indian market are stitched by cotton or nylon threads which compromises the products safety. Braided PTFE coated ropes are used to secure the PTFE Flange Spray shields on the flanges.

Using nylon or cotton ropes will decrease the products life and increase your products cost & maintenance. Velcro cutouts are used on opposite sides for fastening the guard. All our spray shields comes with a litmus patch for easy leak detection in case of a flange leak.

SS316 Flange Guards:

Stainless steel 316 have molybdenum in them which results in resisting of corrosion caused by chlorides. This is one of the most important reason that SS316 Flange Shields & Flange Protector Bands are used in highly corrosive environments i.e near sea shores for flange spray protection. SS316 shield have a high resistant to acid, solvents, chemicals and prevents metallic contamination to the process liquid.

We are the only manufacturer of this type of SS316 Flange Safety Guards in India. The design is very critical to these pipe flange shields. As these guards are used in highly corrosive,high temperature and very high pressure environments. All our SS316 Flange Guards come with multilayer Stainless steel mesh to decelerate the pressure of the liquid effectively. Safe discharge of the process liquid is the objective of these shields as a small error can lead to catastrophic accidents in high pressure and high temperature environment.

As SS316 Flange guards & Flange Protector Band are used in high pressure environment, we have designed a secured double locking feature for the pipe flange shields giving it adequate safety. We test shields on our own testing rig to figure out any abnormalities arising out of design or manufacturing failures.

SS304 Flange spray guards with Nut and bolts are ornamental in nature and would lead to dangerous lateral spray outs.
At all times safety of our manpower and equipment is important and this is the reason these SS316 flange guards & Flange Protector Band are used by Industry Stalwarts like TATA.

PP Flange Guard


High density polyethylene is un-branched which makes it denser than other polyethylene. The structural difference gives the thermoplastic HDPE more strength over other polyethylene.

HDPE - PP Flange Guards have been designed keeping in mind low pressure and temperature. These HDPE PP Flange Protector Bands & Acid Spray shields are widely sold also because of its cost effectiveness. Though we have made these Flange guards cost effective but due care has been taken that Indana Flange Guards perform superiorly to other PP and HDPE Flange Guards available in the industry.

The following Characteristics make the product unchallengeable in its segment:

1. Minimum thickness higher than 1 mm-Maximum varies depending on the pressure requirement. Critical for Flange Guards strength and holding pressure ability. HDPE - PP FLANGE GUARD below 1mm will not hold and disperse pressure properly.

2. 100% UV RESISTANT HDPE - PP FLANGE GUARDS -Polymers are subject to Sunlight which releases ultraviolet radiation. Prolonged exposure to Sunlight causes the Flange guard to crack. Premature cracking of the product will cause accidents as they are tightened against the flanges. Our Flangeguards are UV resistant resulting in LONGER LIFETIME for the shields which reduces your overall cost in terms of cost of product, maintenance, handling and safety.

3. Secured tightening: We take special care in manufacturing of fasteners used for the flange guards. If a fastener used in the tightening of the HDPE PP shield is loose this will lead to the shield becoming ineffective and Failure. The Fasteners used by us are secured tightly to the flangeguard resulting in zero slippage of the guards from the flanges and effective functioning of the shield.

4. All Our Spray shields are bar coded and marked for Size and Pressure. This results in effective fault finding and easy replacement in case of non performance of the HDPE - PP Flange shield.

5. Reusable- In case of flange leaks or failure. Flangeguards can be easily removed and after rectifying the said flange failure, the same shield can be reused. This can be done multiple times with the same shield.

We hold annual rate contracts with several Companies for supply of HDPE PP Flange Guards. We strongly believe in Long lasting relationships with our customers and are committed to deliver Quality at even better prices.
