Bloch, Heinz P.
Heinz P. Bloch resides in Montgomery, Texas. He retired as Exxon Chemical’s Regional Machinery Specialist for the U.S. and has authored or co-written more than 780 publications, among them 23 comprehensive books on practical machinery management, failure analysis, failure avoidance, compressors, steam turbines, pumps, oil mist lubrication and optimized lubrication for industry. Mr. Bloch holds BS and MS degrees (cum laude) in mechanical engineering from the Newark College of Engineering (NCE). He is one of 10 inaugural inductees into NCE’s Hall of Fame, which honors its most distinguished alumni.
Reliability: Reliability and the EPC contractor
In this column, I have often elaborated on critical information related to reliability thinking. However, reliability thinking is continually subverted by approaches that concentrate excessively on project cost and completion.
Reliability: Troubleshoot hot bearings in hot pumps
The reliability engineering unit supervisor (REUS) working at a 400-Mbpd refinery wrote that he was greatly concerned about a bearing temperature excursion. He realized that certain rules of thumb had been handed down to his maintenance employees, and that not all of these conveyed the same numbers and guidance.
Reliability: Monitor equipment condition by collecting vibration signatures
With relatively few exceptions, industry guidelines and standards allow an increased understanding of best practices.
Reliability: Reassess and redirect your approach to a long-term career
It was not too long ago that a prospective employee could expect a 30-year career within an oil refinery or a petrochemical plant.
Reliability: Consider amended warranties for rotating equipment
If you have ever encountered a situation where an equipment manufacturer declined to offer warranties, allow us to share three case histories.
Reliability: Monitor electric motor vibration and optimize motor bearing lubricant application
Follow our discourse with a reliability professional employed by an owner-operator with a number of ammonia and urea plants in locations where blinding sandstorms are prone to occur.
Reliability: Machinery quality assessment on twin-screw compressors
Machinery quality assessment (MQA) is similar to bid conditioning, and both relate to structured efforts.
Reliability: Overcome biases and challenges facing industry
When asked about the challenges facing the hydrocarbon processing industry (HPI), our answer was swift and direct: The trials we face are bundled, or can be found, in lessons some of us learned decades ago. However, lessons learned and explained decades ago were often disregarded by managers with a short-range focus.
How small deviations and lack of management access compromise reliability
In 2013, Refinery “X” was experiencing serious pump distress—the third or fourth in a 12-month period. We received calls about the latest thrust bearing failure event on this important 3,560-rpm process pump. Soon after, a surprisingly similar incident happened at Refinery “Y” in 2015. Both incidents are considered here.
Reliability: Principles are more important than strategies
A number of US oil refineries have recently asked the question, “When should an equipment repair be classified as rework?”
