Please recommend a manufacturer of ball receiving and sending cylinders for docks
Thread Content
Dear experts, please recommend a supplier of ball receiving and sending cylinders for use at the docks of liquefied gas storage companies. Actually, in the past we would draw the designs for these ball sending and receiving cylinders ourselves and have the construction team manufacture them on-site; it was a very simple process. But now we have decided to purchase ready-made units and install them directly. The ball sending and receiving cylinders recommended by the design institute are long and large, with a complex structure – they seem to be suitable for long-distance pipelines or power plants. The cylinders used at docks have a simpler structure and smaller dimensions. I’m not sure if any of you have used them before; could you recommend a brand? Thank you!
It is recommended to use pigging valves, as they are small in size and easy to operate.
Pigging valves generally have doors on the side and are large in size; due to the limited space available, ball receiving and sending cylinders were specifically used
There is a manufacturer named Shenyang Xinlian Petrochemical Equipment Co., Ltd
Shenyang Xinlian Petrochemical Equipment Co., Ltd. provides really good service; I have dealt with them before. It’s just that there’s no way to get in touch at the moment.
You can just make it yourself; it’s a simple pig
The pigging valve doesn’t work well; it’s extremely difficult to operate, and it’s not as convenient as a ball valve.
Is there something wrong with my perception? Cylinders are troublesome to operate and require a range of accompanying components; that’s why pigging valves were developed (they are small in size and easy to operate). Reading the answers in the comments left me confused. . .
Have you made your choice? I need to do a similar job at a dock as well. I would like to consult you. . Do you have a hose there? How do you get the ball past?

For internal floating roof tanks, it is recommended to use pigging valves, as using such valves to pass balls prevents gas from entering the tank, thereby reducing damage to the floating disk. Our company plans to replace the existing ball catchers with pigging valves.
