SURGE VESSELS

Introduction:

A surge tank is a stand pipe or storage reservoir at the downstream end of a closed aqueduct or feeder or a dam or barrage pipe to absorb sudden rises of pressure, as well as to quickly provide extra water during a brief drop in pressure.

We manufacture Surge tanks for Water pipe line, Desalination plants, Crude oil pipe lines and other applications. Horizontal and vertical types are provided. These tanks are Diaphragm type or Air pressure type with compressor. Orifice plates, butter fly valves, Level instruments, pipeline etc. are provided as required.

We belief our equipments are the best, due to high class standards, qualities and long experience of manufacturing such those kind of equipments.

Technical Specification:

Design Code: ASME, AD MERKBALTTER, PD 5500, CODAP 2000 AND OTHERS
Design Pressure: 0 to 70 Bar
Design Temperature: Ambient
Volume: 1 to 200,000 Liters.

Types Of Surge Vessels

Surge vessel shall be of Air pressured vertical, bladder type suitable for open-air installation, subject to the condition that vessel capacity shall not be less than required surge volume for this calculation; we obtain the basic data from the technical data of the surge system and design accordingly.

Types Of Surge Tank:

Surge tank are basically of two types “Air in bladder type “and “Water in bladder type “

Bladder Tanks

Air in bladder type

• These Tanks are charged within bladder inside the tank, and the air losses due to absorption are minimum.
Since, Air does not come into contact with the liquid in the tank.
• The bladder will typically be pre-charged at installation with a pre-determined pressure to give the correct operating level in the tank when the unit is connected to the main and at the operating pressure.
• The bladder is made from a highly elastic rubber, such as butyl rubber, and may be sized to expand to fit the entire vessel.
• The anti- extrusion plate and inlet size are so selected that they do not restrict the flow in and out of the vessel. To prevent the bladder from being drawn into the main at low pressures ananti-extrusion plate is fixed at the outlet of the vessel.
• The tank material is chosen compatible with the liquid since it comes in contact with the tank inner surface while flowing in and out from the main line.

Water in bladder type

• Water in bladder tanks air is charged within the tank and the water from the mains flows in and out into the bladder.
• The bladder is made from a highly elastic rubber, such as butyl rubber, and may be sized to expand to fit the entire vessel.
• The air charge losses due to absorption are minimum since air does not come into contact with the liquid in the bladder.
• The whole tank will typically be pre- charged at installation with a pre- determined pressure to give the correct operating level in the tank when the unit is connected to the main and at the operating pressure.
• To prevent the bladder from being drawn into the main at low pressures ananti-extrusion plate is fixed at the outlet of the vessel.
• The anti- extrusion plate and inlet size are so selected that they do not restrict the flow in and out of the vessel.
• The Bladder material is chosen compatible with the liquid since it comes in contact with the bladder inner surface while flowing in and out from main lines.

Vertical surge tank

The surge tank usually consists of a single or double compartment vessel and a level measuring system with sight glasses or magnetic levels. To prevent overpressure and overfilling, the surge tank is fitted with a pressure-relief valve and a high- and low level alarm system.

All surge tanks are shock-protected by a frame, and operate in the vertical position; even they are transported in a horizontal position.

Features:

Dual-compartment surge tank provide a means to empty one tank compartment while filling another
Sight glasses or magnetic level indicators
High- and low-level alarm on each compartment
Automatic pressure-control valve normally open on gas outlets
Diverter, vortex breaker, and stiffening rings

Applications

Onshore and offshore exploration and development oil and gas well testing
Production wells

Horizontal Surge Tanks

These are used to provide additional wastewater storage but at the same time minimizing construction work. They can be installed in conjunction with a pump station, or can have a pumping chamber incorporated in them.

Flexible Design

Detailed design is finalized in conjunction with customer requirement. Typical diameters are 1800mm through to 3500mm, to lengths required.  Anti-flotation fittings are standard.

FIXTURES

The surge vessel shall be equipped with the following:
Flange outlets
Inspection hole
Drainage plug
Glass tube levels indictor with an isolating valve
Pressure gauge with isolating valve
Safety valve
Air inflation plug
Supporting legs
Lifting lugs
Air Compressor

Applications:

• Offshore and land operations
• Drill stem testing
• Well cleanings
• Production well testing
• Early-production facilities

Connections:

Inlets & Outlets, Manholes up to 900NB, level gauges, Relief valves, Pressure gauges, drains etc can all be built and positioned as best to suit your surge vessel application.
