The so-called hoop, the cover and the barrel body is connected together with the ring, in order to achieve the effect of sealing and fastening. Some only need the fastening effect, you need some hoops can withstand the pressure test barrel without leakage. In this regard, basically no domestic data, the hoop effects are relatively poor, and the principle also rely on their own manual to find out, no specific theory. The hoop to do better in Japan, is characterized by simple appearance, light weight, good effect of pressure test.

Hoop is widely used in barrel, cans, lubricants, coatings, chemicals, petroleum, grain, metal packaging industry. Making hoops two materials: galvanized plate and strip green flowers. The mechanical advantage is a machine and can produce many different sizes of hoops, simple operation, no noise, quality, performance guarantee is known as the world. Product specifications: 18L and 20L metal barrels, chemical barrels, and drum hoops and various accessories; all kinds of 30--200L caliber Portland drums, metal barrels and plastic barrels open hoop, insurance cover. Product use: This product is widely used in essential supplies coopery, cans, lubricants, coatings, chemicals, petroleum, grain, metal packaging industry.

To make the barrel impervious Water Leakage sticks a whole, not only, more important is the process of barrel hoop requirements must be scientific and reasonable and rigorous. One is the hoops must be appropriate, with a barrel hoop between the help of wood stress should be balanced and consistent. The wooden hoop too tight sticking out, when cracks; too loose, wood from hoop constraints inherent in a gap, there is no infiltration of Water Leakage; two is a barrel to keep moist, and dry the bucket of water to leak is caused by shrinkage of dry wood.

The barrel body, the bottom of the barrel, a barrel hoop, including length of the barrel body to make the plate, filled with water, we must first understand their own place of short board, short board because the long board will lose the advantage. Only alternate plate, in order to make more and more bottled water. This is the first enterprise to lay a good foundation, the stronger, then grow out of its consideration of the unbalanced development of the local repair plate, so that the management ability of the balanced and coordinated development, optimize the use of resources.
