Special system requirements and custom designs are available to suit your needs. Strainrite vessels are fabricated from the highest quality materials and conform to code standards. Materials of construction include Carbon Steel, 304, 316, Duplex Stainless, Alloy C 276, Alloy 20, and Titanium.


All Strainrite vessels are hydrostatically tested to 150% of rated working pressure. Special quality assurance tests are available, which include X-ray, Magnetic Particle, Liquid Penetrant, Ultra-sonic and Brinell hardness testing.

The SRID Series Bag Filter Vessels are one of the most commonly used models for our remediation systems. The Strainrite Companies SRID is a technologically advanced Industrial Duty filter bag housing. The SRID series incorporates a unique radial seal design that provides a hermetic seal between the basket and vessel. Utilizing a radial seal with a retainer baskets eliminates "basket rocking", which causes bypass as the basket becomes out of round. "Basket rocking" is common in low cost bag vessels that do not incorporate an o-ring seal and can cause unfiltered liquid bypass. The Strainrite Companies' SRID, with a radial seal, has a machined surface that produces a positive seal to eliminate bypass.

The SRID is perfectly positioned to handle: standard bags, absolute rated filters and high efficiency large diameter pleated hybrid filters (Madd Maxx).
