CASE STUDY Tube and Pipe : Pipe Coating QUAKERCOAT® 547 The Challenge
The Benefits
A leading tubular products manufacturer was experiencing rust on their coated pipe within 1-2 weeks of being stored outdoors. In addition, their coating line constantly struggled with plugged tips leading to the shutdown of the entire process lineThis accumulated to over 259 minutes of lost production time of the tube forming line, hydrotesting line, and NDT processes. These problems entailed further concerns including:
As a result, Quaker Houghton:
• Poor coating adhesion • Persistent downtime from equipment failure • Excessive solvent usage • Environmental VOC complaints scrutiny from the corporate Environmental • Constant Health & Safety Director
the QUAKERCOAT® 547 protective coat• Implemented ing which increased the current protection rate from 1-3 weeks to 3-6 months
and reduced number of spray heads by 50% to • Aligned achieve a uniform film coating of +/-0.1 mil dft around the pipe circumference
• Increased tip size applied coating costs/ mil dft by 10% through • Reduced the use of a higher solids product cleanup costs by 75% due to improved • Decreased drying properties with minimal drain off and drippage the equipment: spray ring, day tank, • Reengineered return pump switching, and filters compose operating plans and conducted • Helped training
The Solution Upon surveying the customer’s operations, the Quaker Houghton team determined that the rusting resulted from an uneven coating with an inconsistent adhesion throughout the length of the pipe. To address the multiple issues, Quaker Houghton assembled an onsite support team to focus on a resolution, worked closely with the operators to understand what challenges they were encountering, and monitored operations for an entire week, 24 hours per day.
a methodology to calculate, document, • Provided and minimize VOC emissions
The optimized use of QUAKERCOAT® 547 and the prompt and in-depth service and technical support impressed the plant personnel.
