Welltec, the international provider of robotic well solutions for the oil and gas industry, approached us when facing the challenge posed by severe internal erosion to the sleeve of their Welltec® Flow Valve (WFV) when pumping a proppant in an onshore well.
A coating was required that could overcome this extreme erosion challenge and enable the valve to operate to optimum performance in this harsh environment. Project economics meant that it was preferable to find a suitable coating solution rather than change the substrate material. Welltec had previously tried HVOF and ceramic coatings but they had both failed, presenting issues of cracking and peeling. Read how we solved the problem here.
