Rohag Singapore Achieves 40% Time-savings on Inspection Checks with FaroArm

Rohag Singapore Achieves 40% Time-savings on Inspection Checks with FaroArm

Founded in July 1997, Rohag Singapore Pte. Ltd. (Rohag) is a leading manufacturer of components and parts for the oil and gas industry. The company is headquartered in Singapore, and places great emphasis on excellence in both its services and products, so as to establish a leading status in the industry. The team at Rohag works with customers to develop quality products made to specifications, delivered at competitive prices and in a timely manner.

Mr. Lee Kong Peng, Managing Director at Rohag, shared, “By focusing on quality, continuous improvement, and innovation, we stay ahead of competition and keep our customers satisfied. At the end of the day, we want them to be confident of our products and services.”

It is this mantra that has guided the company through its journey of nearly two decades. As Rohag supplies components such as wellheads, seal rings, and couplings, the main process involved in production is metal machining, specifically with milling and turning with various computer numerical control (CNC) machine tools and equipment that Rohag possesses. In every project, the team typically conducts inspection on the first article, during production, as well as on each final product before it leaves the facility.

Rohag is a leading manufacturer of components and parts for the oil and gas industry.

In the earlier days, the production team used to rely purely on hand tools such as internal pitch diameter bore gauges, dimensional inspection gauges, and micrometers to conduct inspections and quality control checks on its products. While there were no major issues with these methods, Rohag was still intrigued when a customer recommended the FaroArm to them back in 2007.

The FaroArm is a portable coordinate measuring machine (CMM) that resembles a human arm in appearance. Equipped with several articulating joints, the FaroArm is able to determine and record the location of a probe in 3D space, and report the results through software. In January 2008, Rohag decisively invested in its first 8-ft FaroArm after careful deliberation, and the team has never looked back since.

One of the first few advantages that Rohag noticed was the time-savings that it enjoyed almost immediately. Mr. Lee recalled, “An inspection job used to take us around 5 hours to complete, but using the FaroArm, it would only require 3 hours. That’s a 40% improvement!”

Besides an increase in efficiency, the company also enjoyed other benefits with the addition of the FaroArm to its suite of inspection tools. Using the FaroArm, Rohag began to address larger components that the older tools could not handle. The FaroArm is capable of measuring parts of varied sizes (up to 1250mm) while still providing accuracies of up to 0.001 inch (0.025mm).

The portability offered by the FaroArm greatly simplified the inspection job for the team at Rohag. Instead of having to transport parts to a measurement room, the FaroArm can simply be deployed right on the shop floor, where production takes place. That way, the team saves on the time and effort that would have been spent moving components around. Rohag also minimizes production downtime since quality checks can be done right on the machines as well.

In addition, Rohag gained the new competency of geometric dimensioning and tolerancing (GD&T) on the components. A system that communicates engineering tolerances, GD&T clearly states the nominal geometry of a given part and its allowable variation. “Prior to using the FaroArm, we could not acquire the measurements necessary to perform GD&T analysis on our components,” revealed Mr. Lee. “With FARO’s help, we have learnt how to make full use of the device to obtain such measurements, much to our customers’ satisfaction.”

Since its first purchase, Rohag has added several newer units of FaroArm to its collection of tools at regular intervals. At present, the company owns a total of 6 units of FaroArm, in varying lengths and models. The Rohag team utilizes the portable CMMs every day for at least 6-8 hours, with 3 people sharing a unit at any one time. Business expansion may require further additions, and Rohag may explore devices with non-contact scanning capabilities in the near future.

Evidently, FARO solutions have proven to be useful and Rohag has been pleased with the support rendered by the FARO team. Mr. Lee expressed, “Without a doubt, the FaroArm is our go-to choice for a portable CMM. We are certain that no other device out there would have fulfilled our needs in the same way, and we value this partnership deeply.”
