Advantages of the new generation spray-out shields

• a) they are an extra protection against the loss of containment and enable the creation of safer working conditions,
• b) they help to avoid a plant damage and personnel injury as well as to economize the cost of the production process,
• c) they indicate and warn against leakages and sprays,
• d) they may enable to reduce ATEX zones,
• e) these products are recommended by industrial specialists in different branches and by safety authorities.

We propose proven solutions of the international company Ramco. The RAMCO® spray-out shields are available in a wide range of materials. The selection of the appropriate shield is related to the chemical resistance, temperature and pressure of the medium, and whether these products are used indoors or outdoors. Commonly used protective materials include polyethylene (PE), polyvinyl chloride (PVC), polypropylene (PPL) and PTFE-impregnated fiberglass. A separate group constitute the shields made of stainless steel and metal alloys.

I. Spray-out Shields made of cloth.

The shields are made of chemically proof, high-strength materials and are resistant to the operation of even the most aggressive media. They are made of single or multi-layer fabrics with a transparent or colored form. They are also resistant to sunlight, rain and fumes. They are used for a variety of technical requirements on any installation. These shields are easy to be quickly assembled by one person without tools. They can be installed inside or outdoors. The variability of products includes a variety of materials and styles, as well as special versions on request, for example without window, with window, with drainage, etc.

The ECONO series has been designed to reduce the cost of protection in case of installations with a lower rigor of required safety (lower temperatures and pressures, non-aggressive or low-aggressive media). ECONO shields are made of polyethylene (PE) or polyvinyl chloride (PVC). They are used in strictly defined applications, where the lamination of the fabric with these materials constitutes a chemically and physically unbreakable barrier. The entire series has been thoroughly tested so that the economic advantages of the product do not interfere with the guarantee of safety. Both variants of the ECONO spray-out shields consist of six layers (4 layers of lamination and a double fabric). PVC ECONO shields are available in red, white and completely transparent colors. The spray-out shield PVC ECONO / PE ECONO 60°C.

Spray-out shield made of polypropylene.

The cloth spray-out shield is made of a multi-layer polypropylene fabric on a structural basis. The product is equipped with a pH indicator (supporting the visual detection of a leakage - reaction with a change of color in the event of a leakage - a distinction can be observed for acid and alkali). PPL impregnation is the basic chemical protection of the material. This composition comprehensively completes the offer of spray-out shields for installations with non-aggressive or medium-aggressive medium at temperatures up to 107°C. The spray-out shield PPL 107°C.

The Spray-out shield PPL(v) - VUE type is a modified version of the PPL band. The construction features an "inspection window" made of ECTFE foil (non-flammable, transparent fluoropolymer foil with temperature resistance up to 150°C). This modification allows for additional location of a leakage and visual analysis of the connection status. The spray-out shield PPL(v) 107°C.

PRO series - the most demanding working environment.

The TFE fabric spray-out shield is made of glass fibers impregnated with PTFE on a structural basis. The product is equipped with a pH indicator (enabling visual leakage detection - reaction with a change of color in case of leakage – a distinction for acid and alkali). Impregnation with Teflon (PTFE/TFE) strengthens the physical properties of the fabric with the chemical resistance of TFE. This allows to secure an extended range of applications of the spray-out shields made of cloth in the environment of highly aggressive and high-temperature media.
The spray-out shield TFE 232°C.

The Spray-out shield PPL(v) - VUE type is a modified version of the PPL band. The construction features an "inspection window" made of ECTFE foil (non-flammable, transparent fluoropolymer foil with temperature resistance up to 150°C). This modification allows for additional location of a leakage and visual analysis of the connection status. The spray-out shield PPL(v) 150°C.

EXP series - solution for expansion joints

Compensating connections are an important element of the installation, protecting the operation of pipelines caused by temperatures. However, they are a critical point in the pipeline, being an element highly exposed to leakages. The EXP series is a solution protecting the expansion joints against the effect of medium splash after unsealing the installation, combining the principle of operation of a classic shield - stable and tight separation of a potential leakage from the environment - with the ability to maintain its mounting position, resistant to high pressures even when the expansion joint is in operation, without transferring his job.

The EXP series ties are available in the following variants:

- sTFE-EXP pro,

- sTFF(v)-EXP pro,

- sPPL-EXP pro,

- sPPL(v)-EXP pro.

• - ideal for areas at risk of explosion (electric screwdrivers are not needed),
• - very long service life,
• - resistant to UV radiation and impacts - suitable for outdoor installation,
• - for use at temperatures from -40 to +110°C,
• - in rolls of 50 m.

II. Metal spray-out shields for high pressure and high temperature connections.

Metal spray-out shields are used wherever there is high pressure and temperature, and the use of a plastic shield is not possible. They are recommended for hazardous, corrosive and highly corrosive substances and environments. They are usually used on gas and hot oils installations. This protection consists of an uninterrupted outer layer fastened with a double lock system, equipped with segmented side flanges and a fitted dense mesh inside the band, the purpose of which is to reduce the splash pressure while directing it in the required, safe direction.
Metal flange shields are made in three material variants:

• - galvanized steel,
• - stainless steel, grade 304,
• - stainless steel, acid-proof, grade 316,

A protection in the form of metal shields guarantees no deformation of the cover even at high temperatures (500°C and maximum pressure of 100 bar).

In addition, you can choose from the following solutions:
DR series system drains.
There are plant sectors where leakage should be completely contained. For example:

• - pipeline connections located directly above the communication space,
• - piping systems used for unloading barges, tankers or other water units in order to protect against water contamination,
• - insulated installation,
• - capturing potential leaks for reuse,
• - secondary pollution.

For such conditions, we offer the DR drainage system. The shield is fitted with a drainage removing the liquid accumulated during the leakage. It allows the liquid to flow directly into a suitable vessel. The DR system can be applied to all of the company's anti-spray products, including metal versions.

The above solution is recommended for use inside or outdoors.

In addition it should be stated that:

• - the shields are profiled on the face of the flange. Even the simplest cloth shields without drainage and without a window allow you to identify a leakage by swelling under the action of condensed liquid inside,
• - the variety of materials of the products allows for the selection of an optimal solution for the given operating conditions of the installation,
• - the life of the materials used is very long, and the spray-out shields can be used many times.

Customized spray-out solutions.
If it is not possible to use mass-produced solutions, individual spray-out systems are offered, adapted directly to the required element and the working conditions. The cloth spray-out solution provides a wide range of cover shape possibilities, allowing for an individual approach to even the most demanding objects.
