Silos and Gravity Tube Blenders

Pittsburgh Tank is a leader in the bulk storage industry. Our Dedication to engineering excellence and quality workmanship is only part of the reason why Pittsburgh Tank rises above the rest.


To provide complete customer satisfaction, we first strive to truly understand exactly what each and every customer's precise bulk storage requirements are and how we can deliver a system on time that provides effective, efficient, afforable and durable service. 


Each storage application is unique and requires a system designed in accordance with the customer's specifications. Our silos can be provided in various configuration from fully skirted to leg-supported to gusset supported and in configurations of up to 16 ft. in diameter and heights over 100 ft. 

Gravity Tube Blenders

Each gravity tube blender is a vertical mixing chamber that can double as a storage silo. Through the use of staggered tubes, stored material is recirculated quickly and efficiently with the end result being a uniformly blended material with reliable consistency. 


With optional single, multiple, or chisel cones, divided wall, level sensors, access doors, straight or spiral stairs, ladders, walkways, and/or platforms, if you can think it, we can build it!

All silos and blenders can be one-piece construction, available in carbon steel, stainless steel, or aluminum, thus minimizing field assembly and installation time.


If required due to shipping restrictions, PTC can provide field welded silos at the customer's specified diameter and height to meet their storage demands.
