Preparing & Filling Unisphere Pigs
In this third episode of Pigging Insights, we cover the steps and guidelines to preparing and filling TDW unisphere pigs. These seamless liquid cast polyurethane balls are designed for removal of liquid hydrocarbons and water as well as batch separation for pipelines handling different liquids.
TDW PIGGING INSIGHTS - Episode 3
Instructions for the preparation and filling of TDW Unisphere Pigs
TDW Unisphere Pig
TDW Unisphere pigs are seamless liquid cast polyurethane balls. They are designed for removal of liquid hydrocarbons and water as well as batch separation for pipelines handling different liquids. Unisphere pigs are hollow, they can be filled with liquid and also be inflated with pressure to match the pipeline’s ID.
Preparation for Use
Unispheres must be filled with liquid before use. Water/glycol or light lube oil solutions are recommended. It is best to avoid using pure glycol as a filling solution. The 4 inch to 8 inch Unispheres have one filling valve. Larger spheres have two valves; either valve can be used. Other components required are an inflating valve, valve core, pipe plug, filling adapter and valve core extractor.
Filling Procedure (not including inflating with pressure)
1. Remove inflating valve with a 3/8 in Allen wrench.
2. Fill sphere with liquid using funnel or hose.
3. The opening must be at the top and sphere completely filled with air displaced. Rolling the sphere slightly around can help to settle liquid and displace air.
4. Inspect O-Ring on inflating valve for nicks and burrs, and replace if necessary. Apply lubricant to O Ring and threads.
5. Remove pipe plug, and check the tightness of valve. A valve core extractor is available.
6. Install inflating valve and tighten securely.

USE CASE FOR TDW 3-WAY TEE
A gas operator in PA who was building a compressor station needed to tie in a new branch line to an existing 10 inch natural gas gathering line that was running at 950 psi. The customer did not want to leave a buried flanged connection underground that was in the ground.

10”x 10” 3-WAY TEE on the main line with sandwich valve
A gas operator in PA who was building a compressor station needed to tie in a new branch line to an existing 10 inch natural gas gathering line that was running at 950 psi. The customer did not want to have a buried flanged connection underground and were proposing to weld on a standard fitting, add a long pup piece to the fitting, attach a ball valve to the pup piece, and then bolt on the new 10 inch line to the valve above ground level. There were challenges in terms of the stack up. One issue was the length of travel that a tapping machine would have to navigate, the line needed a pup piece to be welded on, and the 10 inch main line was pigged and needed to remain so.
As an alternative, the Kerr and TDW specialists recommended to the operator to use a 10 inch by 10 inch Full Encirclement 3-WAY Tee with LOCK-O-RING ® Flange and LOCK-O-RING® Completion plug with flow through pig guide bars. This solution had multiple advantages. It eliminated the need for a long pup piece. There would not be an issue with the length of travel the tapping machine would have to navigate, and the line would remain piggable. The gas operator agreed.

For this project, TDW technicians performed the welding of the 3-Way Tee fitting and the 10 inch branch line to the side outlet of the fitting. The Technicians operated the 10 inch Hot Tap and set the completion plug with the pig guide bars.
The result for the gas operator was a new branch line tied in with the 10 inch main line able to be pigged. This was the end result the customer required.
