Overview

T-Type Strainers

What is a T-Type Strainer?

The T-Type strainer is a fabricated device comprising an equal tee fitting with weld neck and blind flange connected to the branch. It is an economical type of strainer used in commissioning or permanent applications, suitable for mounting in horizontal & vertical pipelines. Normally supplied with BW-end connections, flanged-end connections can be provided upon request.

The Barton Firtop T-Type Strainer

The ‘industry-standard design’ houses a single ‘V’ [‘bath-tub’] sieve, which has low open area ratio (100%) and high-pressure loss. With in-house FEA, CFD & live flow-testing, R&D have developed world leading alternative sieve designs; ‘W’ Sieve® with 200% Open Area Ratio & 35% reduction in pressure loss and Treble-Vee® Sieve with 350% Open Area Ratio & 50% reduction in pressure loss. These sieves provides higher dirt holding capacity and extended service life and can be retrofitted into existing plants where pressure loss or frequent blockage is an issue. We manufacture Large Bore T-Type strainers for the Renewable Energy and LNG Industries, with blue-chip clients including: Aker Solutions Bechtel, BP, CB&I, Chevron, Chiyoda, Fluor, Inpex, JGC, KBR, MODEC, QatarGas, Shell & Woodside.
