The steel casing is a circular barrel with empty ends that is hooped with iron sheets according to the size of the hole pile.

The steel casing is used in the process of manually digging hole piles. Due to the unstable soil quality, it is difficult to construct reinforced concrete retaining walls. Therefore, steel retaining walls are used to protect the hole piles to prevent hole collapse and avoid affecting the construction progress and safety.

A steel jacket is a spiral steel pipe typically used to surround and enclose a delivery pipe installed through the center of the pipe. Steel casings are most commonly used in underground construction projects to wrap or protect utility lines from damage. This pipe can be used when drilling horizontally or directionally under roads, rivers, lakes or railways. Generally, steel casing is very durable and versatile, so it can also be used for various construction projects.

Shrouds are available in a variety of sizes and diameters as well as a complete line of straight seam, spiral welded, rolled and welded types.

During the construction of the bridge, in order to achieve the specified bearing capacity, the pile foundation needs to be driven, and the pile foundation construction requires a casing to ensure its verticality and prevent the surrounding gravel from falling and causing collapse. Especially for pile foundations constructed in water, steel casings are used. The steel casing can prevent too much sea water from entering the casing, and can also prevent the corrosion of the drill bit, so set out before the pile foundation construction, and then lower the casing with a diameter slightly larger than the designed pile foundation into the sea water, and use a pile driver to smash it. Into the sea mud, then pump a part of the water, and then lower the drill bit.

BBN Steel is specialized in producing steel casing. If you want to know more about steel casing, please feel free to contact us.

 

Processing advantage

1. The spiral blade produced by the continuous cold rolling method overcomes the shortcomings of the traditional spiral blade production process, such as poor precision, difficult forming and high consumption of materials, and low production efficiency.

2. After the blade is formed, the surface is smooth and the dimensional accuracy and surface hardness are high.

3. Provide continuous integral blades according to the helical length required by customers, with good rigidity, convenient and fast welding and assembly during use.
