ASME Certification – Chemted’s Stamp of Safety, Quality & Global Compliance

At Chemted, ASME certification reflects our commitment to safety, quality, and international compliance. Every product we deliver—whether a pressure vessel, boiler, or process system—is designed and fabricated in accordance with the ASME Boiler and Pressure Vessel Code (BPVC). This ensures our equipment is globally accepted, highly reliable, and built for long-term performance.

What is ASME Certification and Why It Matters

The American Society of Mechanical Engineers (ASME) sets the global benchmark for pressure-retaining equipment. Its BPVC standards define how boilers and vessels are designed, fabricated, inspected, and tested.

For industries like energy, petrochemicals, and industrial refrigeration, ASME certification is more than a requirement—it guarantees compliance, minimizes risks, and builds trust in critical operations. At Chemted, we see ASME accreditation as both a responsibility and a promise to our clients worldwide.
