Brewery Beer Keg
Our beer kegs are made of food-grade 304 or 316 stainless steel, which is stable and neutral, with no chemical reaction to beer, preserving its original taste and aroma. They feature a sealed cylindrical design with a dedicated tap and sealing valve on top, ensuring stable internal pressure while allowing fast filling, dispensing, and cleaning. We offer a wide range of sizes, from 1L, 2L, 5L mini kegs for home use to 10L, 20L, 30L, 50L standard commercial sizes, suitable for various applications.

Main Structure of Stainess Steel Beer Keg
A stainless steel beer keg is mainly composed of a main body, top and bottom heads, reinforcing rings, a spear assembly, sealing parts, handles, and a base.
The main body is cylindrical, made of food-grade 304 or 316 stainless steel, designed to hold beer safely under pressure. It has a sealed bottom head and a top head with an opening in the center for installing the spear.
Reinforcing rings are placed around the top opening and bottom to strengthen the keg, prevent damage during transport and stacking, and keep the keg from deforming.
The spear is the most important part inside the keg. It is a valve system inserted from the top opening, used for gas inlet and beer outlet. It includes a spring-loaded self-closing valve that seals automatically when disconnected, so no beer or gas leaks out. A long dip tube extends almost to the bottom of the keg to draw beer out smoothly.
Seals and gaskets, made of food-grade rubber or silicone, are installed between the spear and the top opening to ensure a tight, pressure-resistant seal.
Handles are attached for easy lifting and moving. The base at the bottom keeps the keg stable and protects it from wear.
When in use, CO₂ gas enters through the spear to pressurize the keg, pushing beer up the dip tube and out through the valve. The whole keg is fully sealed, pressure-resistant, hygienic, and reusable

Application of Brewery Beer Keg
Main Production Equipment for Brewery Beer Keg

Welding Equipment
Welding equipment is used to accurately join the stainless steel body, top and bottom ends of the beer keg together.We use stable and even welding techniques to make the keg stronger and better sealed. This ensures the keg will not crack, deform or leak during long-term use, transportation and pressure use, making it more reliable.

Polishing Equipment
Polishing equipment is used to finely grind the inner and outer surfaces and welding lines of the beer keg.After polishing, the keg surface is smooth, burr-free and has no dead corners, making it easy to clean without leaving impurities or bacteria. It fully meets food-grade hygiene standards. It not only looks clean and nice, but also safer to use.

Pressure Testing Equipment
Pressure testing equipment is key for safety checks before beer kegs leave the factory.We perform strict pressure and air-tightness tests on every keg to ensure stable performance and reliable sealing. This prevents air or beer leakage during use, so customers can purchase and use with complete confidence.
