HDPE spiral wound tanks are the most superior, they have excellent corrosion resistance, high strength, long life, etc., and the appearance can be manufactured in various types such as vertical, horizontal, transportation, and mixing. So how are HDPE spiral wound tanks classified?
Here is the content list:
Due to the different storage media, the forms of HDPE spiral wound tanks are also diverse.
HDPE spiral wound tanks are classified by location: HDPE spiral wound tanks can be divided into aboveground storage tanks, underground HDPE spiral wound tanks, semi-underground storage tanks, offshore HDPE spiral wound tanks, subsea HDPE spiral wound tanks, etc.
HDPE spiral wound tanks are classified by oil product: they can be divided into crude oil HDPE spiral wound tanks, fuel oil HDPE spiral wound tanks, lubricating oil tanks, edible oil tanks, fire water tanks, etc.
HDPE spiral wound tanks are classified by a purpose: they can be divided into production tanks, storage tanks, etc.
HDPE spiral wound tanks are classified by form: they can be divided into vertical storage tanks, horizontal storage tanks, etc.
HDPE spiral wound tanks are classified by structure: they can be divided into fixed roof storage tanks, floating roof storage tanks, spherical storage tanks, etc.
HDPE spiral wound tanks are classified by size: Large HDPE spiral wound tanks above 50m3, mostly vertical storage tanks; Small storage tanks below 50m3, mostly horizontal storage tanks.
The most widely used in China and the most mature production and installation technologies are dome HDPE spiral wound tanks, floating roof HDPE spiral wound tanks, and horizontal HDPE spiral wound tanks.
A vault-top storage tank refers to a steel container with a spherical crown and a cylindrical body of HDPE spiral wound tanks. Vault HDPE spiral wound tanks are simple to manufacture and low in cost, so they are most widely used in many industries at home and abroad. The most commonly used volume of HDPE spiral wound tanks is 1000-10000m 3, and the maximum volume of domestic vault storage tanks has reached 30,000m 3.
Vault HDPE spiral wound tanks mostly adopt this form, which has the advantage of facilitating the pairing of the wall panels of each circle, and it is safer to use the upside-down method for construction.
Floating roof spiral wound tanks are composed of a floating roof floating on the surface of the medium and a vertical cylindrical tank wall. The floating roof rises and falls with the increase or decrease of the medium storage of spiral wound tanks. There is an annular sealing device between the outer edge of the floating roof and the wall of the spiral wound tanks. The medium in the spiral wound tanks is always directly covered by the inner floating roof to reduce the volatilization of the medium.
Floating roofs: spiral wound tanks floating roofs are divided into single-disc floating roofs, double-disc floating roofs, and float-type floating roofs.
Single-disc floating roof: spiral wound tanks consist of several independent compartments to form a ring-shaped floating vessel, and the inner side of the ring is a single-disc roof. The bottom of the top plate of spiral wound tanks is provided with multiple ring steel rings for reinforcement. The advantage is that spiral wound tanks are low in cost and easy to maintain.
Double-disc floating roof: spiral wound tanks are composed of the upper plate, lower plate, and cabin edge plate, and are divided into several independent spiral wound tanks by radial partitions and circumferential partitions. Its advantages are high buoyancy and a good drainage effect.
