MJW Cryogenic Welding Capability Supports Airgas Helium Project // May 2018


MJW Consolidated’s specialized cryogenic welding certification and experience was critical to the success of the recent helium compressor installation for Airgas in Orange County, FL.

With this specialized capability, MJW can weld materials that are exposed to the coldest temperatures encountered in industrial applications. The welds for the Airgas helium project are certified to withstand temperatures of minus 452.2 degrees Fahrenheit.

The work involved upgrading the Orange County site’s helium processing capabilities with a higher-capacity compressor, new vaporizer and an updated analysis and instrumentation system.

MJW installed the new equipment and fabricated new piping for the system. Crews also fabricated and installed a new network of tubing to extract samples for purity analysis and constructed a new instrumentation room. MJW self-performed all of the work that was part of the contract.

The helium line was only shut down for three weeks to accommodate the upgrade. MJW performed the work safely and on time while coordinating with Airgas managers to avoid interference with production activity throughout the large facility.

Airgas, a subsidiary of France-based Air Liquide, is a major supplier of compressed helium used primarily in welding applications. The company’s Orange County plant supplies much of the helium used by NASA at nearby Kennedy Space Center.

U.S. Navy Exchange Gets Upgrade with MJW Help // April 2018

MJW Consolidated is serving the consumer needs of the large U.S. Navy community in Jacksonville, FL area by assisting in the renovation of the Mayport Main Navy Exchange (NEX).

MJW has contracted with Vetfed-Pacifictech JV-1, a joint venture Pacific Tech Construction and Vetfed, to provide mechanical and plumbing construction services, as well as interior remodeling work, as part of an extensive renovation of the 28,000-foot store in Atlantic Beach, FL. The work, which began in October 2017, is taking place in four phases, with completion scheduled for August 2018.

Serving thousands of Navy families at Naval Station Mayport, the store provides a wide range of consumer goods and services. MJW’s scope of work is focused on upgrading and relocating a variety of systems, including refrigeration systems, HVAC systems, a vacuum system, and restroom and food service plumbing.

The project has demanded close coordination with multiple contractors on site, as well as compliance with base security protocols. MJW has a strong relationship with Pacific Tech, having partnered successfully with the firm on several previous military base projects.
