Sherwin-Williams Protective & Marine has launched the new Pipeclad Frac-Shun erosion-resistant coating (ERC) that protects against erosion inside pipes located near fracking wellheads, thereby extending their service life

The inner walls of pipes, especially elbows, located near wellheads can be eroded by fracking sandflows within six to 18 months, or sooner. Such erosion also occurs inside storage vessels and tanks where gritty, multiphase fluid flows strike interior surfaces, often leading to unexpected maintenance shutdowns following pipe wall thickness inspections.

Protection against sandblasting action

The patent pending erosion-resistant coating (ERC) technology protects pipe interiors from the inherent sandblasting action of grit moving rapidly through the pipes. The applied powder coating remains intact far longer than other options, protecting the steel pipes from the metal loss that otherwise leads to potential leaks and early pipe replacements in many operations.

“High velocity fluids containing sand, rocks and other debris moving through a coated fracking pipe create a sandblasting action that’s akin to removing coatings when preparing a surface for a new application,” said Kristin Leonard, Energy Segment director, Sherwin-Williams Protective & Marine. “Once those coatings are gone, the steel will begin to erode instead. The new erosion-resistant coating system is able to withstand the impact of multiphase flows striking it without eroding or chipping away like most coatings. The ERC essentially spits the bullet back out after it’s fired at the surface. With the coating intact, abrasive fluids have no chance at eroding the steel.”

Lab tests and long-term field trials have confirmed the adhesion and chemical and erosion resistance characteristics of the new technology, the company says.

thyssenkrupp Uhde, and Johnson Matthey (JM), are teaming up to offer a fully integrated low carbon (blue) ammonia solution that is more climate-friendly than current production methods

Demand for ammonia is growing because it is easier to store and transport than pure hydrogen, given it can use existing infrastructure, and is key to decarbonising the world’s power, shipping, and industrial processes.

The solution will combine thyssenkrup Uhde’s uhde ammonia process and JM’s hydrogen expertise through its LCHTM technology, which will enable the production of blue ammonia with up to 99% CO2 capture. thyssenkrupp Uhde has licensed, engineered, or constructed over 130 ammonia plants worldwide since 1928 and is market leading in plants greater than 3,000 metric tonnes per day with its unique uhde dual pressure technology. JM’s LCH technology, which utilises JM’s autothermal reformer alone, or in conjunction with JM’s gas heated reformer, has been selected for several of the world’s first large scale blue hydrogen projects.

Lucretia Löscher, COO thyssenkrupp Uhde, said, “At thyssenkrupp Uhde, we are committed to our purpose, ‘we create a livable planet’. With this strong partnership we further broaden our portfolio of climate-friendly solutions and can help our customers even better to reach their sustainability goals.”

Alberto Giovanzana, managing director – Catalyst Technologies at Johnson Matthey, said, “We know multiple routes are needed in the energy transition, and ammonia provides several options because it can be used directly in power and shipping industries, and as a hydrogen carrier to safely transport hydrogen to areas it is not easy to produce. Combining our expertise and over two decades worth of partnership with thyssenkrupp Uhde, we are excited to offer this technology which will allow our customers to produce ammonia with significantly lower CO2 emissions.”
