The GL61W welded T-type strainer is a high-efficiency pipeline filtration device featuring a high-strength body and welded connection ends, specifically designed to intercept and remove solid impurities from fluid media. By utilizing a welded connection, this product completely eliminates the leakage risks associated with gasket failure or bolt loosening in traditional flanged connections, making it ideal for high-pressure, high-temperature, flammable, and explosive conditions or systems requiring extreme hermetic integrity. Its unique T-pattern structure allows for online cleaning by simply opening the end cover without removing the entire valve body from the line. With exceptional pressure strength, minimal flow resistance, and long-term reliability, this product is widely used in petroleum, chemical, natural gas, power, and long-distance pipeline systems as an ideal pre-protection device for pumps, instruments, pressure reducers, and precision control equipment.

1.Superior pressure performance and safety:The body is made of high-quality cast steel or stainless steel, and the integral welded structure provides extreme mechanical strength and impact resistance. The flange-free design minimizes potential leak points, ensuring the inherent safety of the pipeline under high pressure and complex stress.
2.Efficient streamlined T-pattern design:The internal cavity is hydrodynamically optimized with wide channels and a large effective filtration area. The fluid resistance is extremely low, effectively reducing initial pressure drop and achieving energy savings while meeting high-flow requirements.
3.Top/Side quick-opening maintenance:Designed with a top-entry or side-entry maintenance cover. When cleaning is required, only the fasteners need to be loosened to extract the basket. The operation is simple and does not interfere with the piping layout, significantly shortening downtime.
4.Precision stainless steel screen:The filter element utilizes high-strength stainless steel multi-layer composite or wedge wire mesh, offering high mechanical strength and erosion resistance. Filtration precision can be customized to reliably intercept weld slag, rust, and other particulates.
5.Erosion resistance and structural stability:Reinforced internal guiding structures guide the flow and cushion direct impact on the mesh. The robust structure prevents vibration or mechanical fatigue under high-velocity conditions.
6.Wide material and condition adaptability:Available in cast steel (WCB), stainless steel (304/316L), and more. Surfaces can be coated or hardened to handle water, oil, steam, and various corrosive gaseous or liquid media.
7.Compact and lightweight layout:Compared to flanged strainers, the welded connection significantly reduces overall dimensions and weight. This saves space and lightens the mechanical load on the pipeline and its supports.
8.Low long-term O&M costs:The all-welded structure requires almost no secondary bolt maintenance. Highly standardized internals ensure easy interchangeability. Its durability and maintenance efficiency offer clear advantages in total lifecycle costs.
