3 Fig. 7 / 17 / Strainers Removal of debris from fluid transfer systems is vitally important in protecting the performance of pipeline equipment. orrosion deposits, scale, jointing compounds and welding slag as well as more unusual articles must be trapped and prevented from causing system contamination and subsequent problems. Fig 17 The Y type design offers a reliable, cost effective means of equipment protection, minimising downtime and maintenance costs. Fig 7 Figure 7 and 17 Features Bronze construction Threaded end 1/ 2 to 2in. Streamlined flow contours minimise pressure drop. ompact design with short face to face. Perforated stainless steel screen aptive asbestos-free non-stick gasket. omprehensive flow characteristics available. Fig Figure Features Bronze construction Flanged to BS EN PN25. Streamlined flow contours minimise pressure drop. Suitable for HTHW and saturated steam. aptive asbestos-free non-stick gasket. Perforated stainless steel screen vailable up to 15mm Bolted cover 65mm and above. omprehensive flow characteristics available. Design of the Hattersley strainer is backed by years of experience in fluid handling particularly in the field of strainer manufacture and under an approved Quality System to BS EN ISO 91, a quality product is guaranteed. Screening Straining is by the process of direct interception where the fluid passes through the perforation holes in the element the size of which are small enough to prevent passage of the particles. The Hattersley screening element is constructed from perforated stainless steel sheet in accordance with DEO Spec.36 requirements and is inherently stronger than weak mesh type elements which are susceptible to breaching when partial blockage causes increased pressure drop or collapsing under transient vacuum conditions. 3
