Products Introduction

This storage unit consists of an inner tank with 9% nickel alloy steel and an outer tank with Pre-stressed Concrete or Reinforced Concrete. The space between inner and outer tank is insulated with loose perlite and fiberglass blanket. This type of tank is suitable for the cryogenic storage product such as LNG, LPG and Ethylene. Storage temperature is under -100 degree Celsius.

The basic structure is the same as above, but carbon steel plate is used for outer tank. This type of tank is suitable for the low temperature storage products such as LNG, LPG and Ethylene.

This type of storage tank has the basic construction of ordinary dome roof tanks. The outer surface of shell and its adjoining area is insulated against heat leak and humidity penetration with polyurethane foam, foamglas or similar materials. This unit can be used to store liquefied gases such as butane and ammonia, which have a relatively high critical temperature.

Made of metallic outer and inner tanks with perlite filled in between, the tank is suitable for storing LNG and liquefied nitrogen. Operation and control is easy with its design versatility for high operating pressure.

More detail

Roof section is floating on the stored product, and sealing device is installed on the peripheral space between roof and shell plate to prevent the stored product from vaporization. This type of tank is suitable for storage of high volatile products such as crude, gasoline, naphtha, etc.

Tanks with conical fixed roofs are commonly used for storing low volatile products such as heavy oil, kerosene, diesel oil, water, etc.

Reference and characteristics of dome roof tank is the spherical surface of roof which have higher strength to the tank internal pressure than cone roof tank. This type of tanks is applicable to volatile products, and N2 gas blanket system is commonly installed when high-volatile product is stored.

Products which are liquefied at normal atmospheric temperatures and high pressures, such as butadiene, butane, and many other petrochemical products are stored most economically in spherical pressure tanks.

This type of spherical tank, consisting of inner and outer sphere, is suitable to store small volumes of liquefied gases at cryogenic temperatures such as ethylene, oxygen, nitrogen, etc., compared to flat-bottomed cylindrical tank. The space between inner and outer sphere is insulated with perlite.

This type of vessels is used to store the liquefied products which are liquefied at normal atmospheric temperatures and high pressures, and suitable for relatively small capacity(less than 100m3). Commonly, this unit is fully assembled at fabrication shop and delivered to the site.

On the occasion of the installation of tanks, perform the new construction, modifications, and tie-in work to the existing facilities for piping and its supporting structures.
