December 27th, 2011 Comments off

56 Externally Pressurized Expansion Joints

The externally pressurized expansion joints are 37.5″ in diameter and 36″ face-to-face. The bellows are 304 stainless steel, and the flange and ring are carbon steel. This expansion joint is rated for 232 psig with 5″ axial compression and temperatures up to 189°F. All bellows longitudinal welds were 100% x-rayed, all carbon steel welds were dye penetrant examined and each unit was hydro-tested to 348 psig. A total of 56 units were fabricated for a cooling system in a new university for women in the middle east.

U.S. Bellows Acquires Lortz Manufacturing & Doubles Manufacturing Capabilities

December 2nd, 2011 Comments off

A Houston-based expansion joint manufacturer, U.S. Bellows, Inc. has acquired all bellows assets of the former Lortz Manufacturing company. This acquisition includes the fabrication equipment, expansion joint and bellows drawings, design software, customer lists, and all engineering history and other historical data associated with Lortz Manufacturing.

The expansion joint equipment was transferred from Bakersfield, California to the U.S. Bellows facility in Houston, Texas. The additional machines will be incorporated into the current U.S. Bellows location, and therefore significantly expand U.S. Bellows’ ability to provide high quality expansion joints more quickly and efficiently to customers around the world.

U.S. Bellows will be hiring and relocating some of the former Lortz welders and other employees to their manufacturing headquarters in Houston. Besides expansion joints and bellows, the company also offers field services and quick-turn service for emergency situations. U.S. Bellows has over 50 years of experience and is prepared to provide expansion joint repair, refurbishment or replacement for past Lortz-supplied expansion joints.

U.S. Bellows, a member of the Expansion Joint Manufacturers Association (EJMA), supplies an assortment of metallic and fabric expansion joints for a wide variety of applications.
