Hotfoil-EHS Expanding to United Kingdom with New Engineering and Manufacturing Center

Hotfoil-EHS UKHamilton, N.J., June 8, 2018 - Hotfoil-EHS, Inc., America's premier manufacturer of industrial heating equipment, announced today the opening of their United Kingdom facility in Birmingham, England.

"The opening of our UK facility signals a homecoming of sorts, since our original company, Hotfoil, was founded in the mid-1960's in England,” said Hotfoil-EHS President, Matt Richards. “The Birmingham location makes perfect sense for Hotfoil-EHS. After several ownership changes, my father, Neville Richards, took ownership in 1993." Richards continued, "Since then, we have grown though key acquisition and new product development. This move also is the first step in our aggressive strategy to expand into the international market.”

The new Hotfoil-EHS facility in Birmingham will provide the UK with a large local inventory of power consoles, recorders, ceramic heaters, and a full line of accessories used for heat treatment. Hotfoil-EHS UK will also supply hopper heaters, tank heaters, vessel heaters as well as control systems.

According to UK General Manager David Robbins, “The opportunity to introduce such a high quality product line to the UK is wonderfully exciting. I am delighted to be working with such a well established US company and progressive management team."

The Importance of Post-weld Heat Treatment for Welding Repairs

welding
Welding is the process of melting two metals together. During the welding process, the metal is exposed to very high temperatures and undergoes a phase change, first from solid to liquid, then back to solid as it cools.

During welding, residual stresses are formed in an area referred to as "the heat affected zone" or HAZ. In the HAZ, differential contractions occur as the metal heats, liquifies and then cools to ambient.

Residual stresses have a significant impact on the performance of a weld and their reduction is highly desirable. The undesirable impact of residual stresses in welded metal structures involve fatigue performance and corrosion resistance.

Welding repairs are increasingly a structural integrity concern for aging  equipment such as pressure vessels, piping systems and other large steel systems. The make up of residual stresses near repair welds can be drastically different from those residual stresses of the original weld.  Post-weld heat treatment (PWHT) is used to reduce residual stress in steel and and should be used for welding repairs ( as well as on new welds).

PWHT is proven very effective in reduction of high residual stress around the weld repair. Conventional PWHT can be done by combustion furnace, induction heaters or electric resistance heaters (ceramic pad heaters). Accurate ramp and soak times, as well as data recording can be done with modern power console systems. It is strongly recommended to apply PWHT for all original and repair welds.
