UniCast Spheres

Meter Proving and Pipeline Sphere

Overview

Making Accuracy Seamless

The UniCast Sphere is a seamless, inflatable meter proving and pipeline sphere with enhanced durability and unwavering precision. Each sphere features a design optimized for elasticity, wear-resistance, and operational lifetime, while also eliminating seam splitting and delaminating during service. Along with our exceptional factory support, our spheres have become ubiquitous with the Petroleum industry globally, and the first choice for accuracy.

Features at a Glance

The unified exterior of the UniCast Sphere is molded into one inflatable continuous shell of polyurethane that prevents splitting and retains its “Sphericity.” While other two-piece spheres can inflate into an egg-shape, our one-piece construction helps the UniCast Sphere maintain a truer diameter, giving the most accurate measurement.

Two Weights

Our UniCast Sphere comes in two weights, Standard and Heavy. The standard weight UniCast Sphere is ideal for normal operations while the heavyweight UniCast Sphere should be utilized in high turbulence applications. In the weighted spheres, the weight is cast into the internal bladder, which will help contain the weight in the event of the catastrophic destruction of the sphere.

Low Friction

Offering a low friction sphere for dry, non-lubricating products to reduce sphere chatter. Tests have shown a 38% reduction of friction with this product.

Accessories

We have several sphere acessories to aid with inflation and handling during routine maintenance and/or replacement.
