Flow Tees

Rice is proud to work with WeldFit to bring their comprehensive suite of piping products to Canada.

Often used in lieu of a barred tee in locations such as the station bypass adjacent to a pig launcher or receiver, WeldFit's Flow Tee is a specialty fitting that is designed to enable the passage of pipeline pigs and spheres through branch tee connections – a location where pigs often become stuck, restricting critical product flow.

Comprised of an oversized extruded outlet tee with forged end pieces and a slotted inner sleeve to guide the pig through the pipeline past the branch, the Flow Tee permits maximum product flow through the tee and branch connection with minimal pressure drop under normal operating conditions. The slotted holes in the inner sleeve coupled with the annulus provide a flow area at least equal to the flow area of the branch line, allowing a continuous flow of product around the pig as it passes the opening.

Typically designed to ASME B31.4, B31.8, or other applicable design codes, Flow Tees can be supplied for all pipeline sizes, with size-on-size or reduced branch outlets, and to meet almost any pressure rating. Flow Tees can also be provided with weld end or flanged end connections.
