Our Commitment to Our Community

A&B Process Systems is proud to be a respected, successful employer in Stratford, Wisconsin and Central Wisconsin from which we draw many of the extraordinary associates who contribute to our success. A&B provides local students with annual scholarships, trains high school students to be hard workers, and helps them become good, caring business people.

We’re a member of the School-to-Work Program, and many of our current employees and best craftspeople are former participants. We’re proud, engaged members of both the Stratford and Marshfield Chambers of Commerce and frequently volunteer time and money for area events.

Our Commitment to Quality Assurance

At A&B Process Systems, quality means meeting our customer’s requirements – every time.

Our certified fabricators and fitters are trained through our in-house training program. Our stainless steel process systems, stainless steel tanks and stainless steel vessels are fabricated in ASME-certified facilities and then pass through the A&B Process Systems Factory Acceptance Testing Center before leaving our facility. Factory Acceptance Testing ensures that each process system meets regulatory guidelines and is ready for production and integration into our customers’ existing systems without interrupting plant production.

We also provide automated welding processes, such as orbital welding, to ensure sanitary and high purity piping systems for our customers.

All of our fabricators work closely with engineering and design teams to ensure each system not only exceeds your expectations but also meets the regulatory standards that control your manufacturing processes including: FDA, USDA, 3-A, cGMP, API, BPE, ASME (U & R) guidelines.

In-process and final inspections are performed by plant managers, A&B’s full-time quality assurance inspectors and third-party agencies to ensure specifications are met. Testing is done in accordance to specification and regulatory requirements. Some of the quality assurance inspections we perform are:

• Visual Examination
• Boroscopic Examination
• Liquid Penetrant Testing
• Hydrostatic Testing
• Radiographic Examination
• Surface Roughness Testing
• Riboflavin Testing
• Passivation Testing

Test results become part of the equipment turn-over package reviewed during Factory Acceptance Testing and provided at time of shipment.

Quality Standards We Adhere to:

A&B consistently meets or exceeds the requirements for each project by following a Quality Control Manual and continual development of SOPs (Standard Operating Procedures). During fabrication, weekly scheduled meetings are held to discuss fabrication schedule, material issues, and quality concerns. Welding is done by using weld procedures and qualified welders per ASME Boiler and Pressure Vessel Code Section IX. Our staff embraces teamwork and attention to detail to meet or exceed all required guidelines for your industry such as:

• ASME Boiler and Pressure Vessel Code Section VIII Division 1 U Stamp
• ASME Bioprocessing Equipment
• ASME B 31.3 Process Piping
• CSA (Canadian Standards Associateion) Standards

• PED (The European Pressure Equipment Directive) Requirements

• USP NF 21

Providing a safe work environment for our employees is one of our core values that carries through to the products we design for our customers. We design and build stainless steel process systems, tanks and vessels that support our customers’ desires to offer ergonomically sound work environments that can improve their overall plant safety and productivity.


We are also stewards of our environment and work to preserve the beauty that surrounds us. We design systems that reduce product waste, which not only save precious dollars but also improve the amount of product that is dumped to drain. We are a leading supplier and major supporter to the renewable energy industries, and practice LEAN initiatives to reduce energy costs by maximizing efficiency. We also encourage our employees to be good stewards of the environment. Preserving nature and paying close attention to energy costs comes easily to us because we live in North Central Wisconsin where enjoying nature all year long and staying warm during our invigorating winters is a way of life. It’s hard not to be green, here.
