Underground Horizontal Drainage tanks type EP

Types of drainage tanks

Industrial tanks are divided into two categories: EP and EPP.

• EP drainage tanks are steel reservoirs designed to accumulate industrial water, acids, alkalis, gas condensates, transformer oil, and petroleum products. They are not equipped with a heating function and can withstand pressures up to 0.07 MPa.
• EPP drainage tanks have a similar design, but are additionally equipped with a heating element. This allows them to be used in regions where the ambient temperature drops below the freezing point of the stored liquid.

Each category has several standard sizes. For example, the EP 8-2000 option has a volume of 8 cubic meters and an internal diameter of 2000 mm.

Description and purpose of our drainage tanks

A drainage tank is a horizontal reservoir for collecting oil refining products, waste water, industrial oils, and other substances that require special storage and disposal conditions. Tanks of this category can be used to store any liquids with a hydrogen sulfide content of no more than 1.8%.

The use of horizontal tanks is relevant for enterprises where improper disposal of technical liquids can harm the environment.

The following objects fall into this category:

• enterprises for the extraction and processing of oil and gas;
• chemical production;
• petrol and gas stations;
• pharmaceutical companies;
• factories producing fertilizers and pesticides;
• mechanical engineering enterprises.

In some cases, the use of such tanks is also in demand in private farmsteads. In regions with heavy precipitation, the use of horizontal tanks allows you to get rid of excess liquid on the site.

Operating principle

Drainage tanks are manufactured according to TU 3615 145 00217298 2001 from steels resistant to corrosion and flammable substances. The design is a horizontally located tank equipped with a receiving tube. The substance enters the tank through it. Pumping equipment is used to pump out the working medium.

To ensure safe operation, various sensors and control and measuring devices are connected:

• thermoelectric converters;
• thermometers;
• pressure gauges;
• level gauges;
• signaling.

The system is also equipped with automation that stops operations when certain characteristics go beyond acceptable limits.

Construction of EP/EPP tanks

Structurally, both types of tanks consist of the following elements:

• sheet steel body;
• liquid filling pipe;
• emergency product discharge pipe;
• breathing tube;
• ladder for descent;
• metal support;
• two hatches.

One hatch is intended for lowering pumping equipment, the second - for servicing the tank.

Models of the EPP category are additionally equipped with a heating element. This can be a coil or a heating cable.
