Sub Item

1. Pressure / Vacuum Relief Valve

The pressure/ vacuum valve is a protection device mounted on a nozzle opening on the top

of a fixed roof atmospheric storage tank. Its primary purpose is to protect the tank against

rupturing or imploding. Without an opening or a controlled opening, a fixed roof atmospheric tank

would rupture under increasing pressure caused by pumping liquid into the tank or as a result

of vapor pressure changes caused by severe thermal changes. Imploding, or the collapsing

of a tank, occurs during the pumping out procedure or thermal changes. As the liquid level

lowers, the vapor space pressure is reduced to below atmospheric pressure.

This vacuum condition must be alleviated through a controlled opening on the tank. In short,

the tank needs to breathe in order to eliminate the possibilityu of rupturing or imploding.

Because of its primary function, a pressure/ vacuum valve is commonly referred to

as a "breather valve".

2. Flame / Detonation Arresters

Flame arresters are fire safety devices.

They prevent flames from entering a tank and also provide protection from flashes

within a tank. They can also be used as an in-line flashback prevention device.

3. Emergency Relief Valve

The primary function of the emergency relief valve is to provide a controlled opening on a tank

that will be large enough to prevent rupturing of the tank under severe pressure increases

caused by close proximity to intense fire. Each of these safety devices are used on the

atmospheric, fixed roof, non-refrigerated, storage tank.

4. N2 Blanketing System

The corporation win MODEL WNBS blanket gas regulator ensure that a constant gas pressure

is maintained in the vapor space of a storage tank. When liquid is removed from a tank or the

temperature is reduced, a vacuum would be developed. With the corporation win blanket gas

regulator, a blanket gas is supplied to prevent any vacuum from developing and to maintain

the desired blanket pressure. In addition to preventing outside air and moisture from entering

the storage vessel. The result not only conserves product but also greatly reduces emissions.

These advantages are in addition to the fire protection that is provided.

5. Solt Deeping & Sampling Device

Model WDD50 series is used to gaging the height of liquid level, taking temperature and taking

samples of liquids held in storage tank without relieving pressure within the tank.

It avoids the loss of valuable vapours and exposing the gauger to excessive fumes.

6. Central Type Swing Joints

The Corporation WIN MODEL WSJ series constructed of only four major parts, a cast iron "V"

shaped yoke, a specially manufactured tee and two and two bronze bushing with o-ring

sealsthe huber staytite swing joint is balanced, leak tight and has no tendency to tilt

or pull apart. MODEL WSJ SERIES SWING JOINT is hydrostatically tested to 4-6kg/Cm2G

to insure sound and leak tight assembles and The flanged tee is precision aligned and

rotates on large stationary, bronze bushings which are hydraulically preassure into the yoke.

7. Rotary Jet Mixer

The WIN ROTARY JET MIXER is a device for directing a submerged jet of crude oil across

a pre-selected area of the bottom of a crude oil storage tank. This jet of crude oil dissolves

and re-suspends the accumulated sludge throughout the overhead oil.

The WIN ROTARY JET MIXER MACHINE is fluid dynamically-powered, the nozzles being

gerbox-driven by a fixed-blade impeller assembly which is rotated by the continuous flow

of fluid through the Machine.
