Technical Mechanical Engineering and Quality Control

All Filterfab manufactured new replacement parts and equipment are designed and manufactured to meet or exceed the needs of the customer’s application. For example, one of our engineering standards is finite element analysis (FEA) for machine framework and component parts. 

We reference the following codes as guidelines for design and manufacture:

Welding – ASME BPVC Section IX

Vacuum Components and Systems – ASME Section B31.3

Materials -- ASTM standards such as:  

• Carbon Steels: A-36, A-53, A-106, A-366, A-500, A-513, A-519, A-569
• Stainless Steels: A-213, A-240, A-249, A-262, A-269, A-276, A-312, A-511
• Corrosion-resistant alloys: B-574 (C276)

Other specialty materials may be selected to suit specific applications.  For example, valve bridge blocks may be constructed from specialty abrasion resistant wear steels.  Valve internals may be hardened by the process of overlaying wear resistant deposits on specific internal surfaces.

Electrical Enclosures - NEMA 250-2003

Surface Preparations and Protective Coatings - SSPC SP3 / SP6 & 2 coats of epoxy paint to all exposed carbon steel surfaces.

Rubber Compounds – Filterfab has both hot and cold vulcanizing rubber compound capability.  Hot vulcanization is our standard.  Rubber-covered components are carefully prepared, laid up and then autoclaved under pressure, yielding the highest quality finished product.  If required, parts are post machined to the final dimensions and finish.

Quality Management System

The Filterfab Quality Management System satisfies the intent of ISO 9001:2015.  Our quality control program relates first and foremost to the safe operation and safe maintenance of all Filterfab equipment. In addition to paramount safety goals, the customer’s needs, requirements, and expectations are central to providing the Filterfab process of improving quality.  Full employee involvement from the Filterfab Equipment General Manager to the individual millwright is key to ensuring that each individual’s skills will produce the final quality product.  

Filterfab manages a quality process that includes the following controls:

• Control of Documents
• Control of Records
• Internal Audits
• Control of Nonconforming Components
• Corrective Action
• Preventive Action

Continued improvement in performing to the Filterfab quality standards is a permanent objective. Feedback data and information is analyzed in order to make detailed quality improvement decisions. Filterfab works closely with valued suppliers in order to ensure a consistent and mutually beneficial relationship which results in the reliability of performing Filterfab equipment. Customer satisfaction expectations are clearly defined and tracked in order to achieve continual improvement benchmarks. Specialized QC procedures and testing are available and may be requested prior to quoting. These tests include penetrant, x-ray, and helium leak testing.
