Shanghai Power Plant Valve Factory Co., Ltd. (SDF) engineers and manufactures high-pressure industrial strainers. We design these units specifically for demanding high-temperature environments. As a critical component in fluid control systems, they protect expensive downstream equipment. This includes pumps, meters, and control valves. Our filtration units prevent damage from debris and particulates. By integrating advanced R&D and precision manufacturing, SDF ensures maximum reliability. Our pipeline strainers deliver an extended service life in challenging industrial applications.
Selecting the right filtration solution is vital for system efficiency and safety. We offer a diverse range of pipeline strainers. Each is engineered to meet specific flow capacities and pressure ratings. Explore our primary configurations below to find the ideal match for your facility.
Our Y-type strainers are the industry standard for high-pressure steam and gas. They work best in liquid applications with low solid particulate levels. Featuring a highly compact design, these units offer exceptional installation flexibility. You can mount them in both horizontal and vertical pipelines. Their robust construction withstands extreme pressure fluctuations. They effectively capture debris before it reaches sensitive downstream machinery.
Simplex basket strainers provide an optimal solution for high flow capacities. They also ensure a minimal pressure drop. These models feature a larger filtration area compared to Y-type designs. This makes them highly effective for liquids with higher particulate loads. We designed them with maintenance in mind. They include an easy-to-remove basket feature. This allows operators to perform quick cleaning with minimal pipeline downtime.
Duplex strainers are engineered for continuous flow systems. They are ideal when pipeline shutdown is simply not an option. This innovative design features two separate basket chambers. A diverter valve connects these two sections. When one basket becomes full, operators can seamlessly redirect the flow. The fluid moves to the clean chamber. This allows you to isolate and clean the dirty basket during full operation.
Standard configurations may not meet every unique project demand. Therefore, SDF offers comprehensive capabilities to engineer custom fabricated strainers. Our technical team works closely with clients to tailor each unit. We accommodate unique pipeline dimensions and exotic construction materials. We also provide specialized mesh linings. This ensures precise filtration levels for highly specialized industrial processes.
