Bloch, Heinz P.

Hydrocarbon Processing Staff, Montgomery, Texas

Heinz P. Bloch resides in Montgomery, Texas. His professional career commenced in 1962 and included long-term assignments as Exxon Chemical’s Regional Machinery Specialist for the U.S. He has authored or co-written more than 770 publications, among them 22 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 an ASME Life Fellow and was awarded lifetime registration as a Professional Engineer in New Jersey. He is one of 10 inaugural inductees into NCE’s Hall of Fame, which honors its most distinguished alumni.

Reliability: Consider today’s canned motor pumps

Bloch, Heinz P., Hydrocarbon Processing Staff

We often make the mistake of letting our equipment selection decisions be governed by old data, anecdotes and traditions.

Reliability: Preserve what worked well in 1980

Bloch, Heinz P., Hydrocarbon Processing Staff

The second CCC implementation strategy involved so-called “shirt sleeve seminars.”

Reliability: Guidance for a lube sampling program

Bloch, Heinz P., Hydrocarbon Processing Staff

Suppose your manager asked you to be involved in setting up a lube sampling program.

Reliability: Consider stainless steel tubing for mechanical seal connections

Bloch, Heinz P., Hydrocarbon Processing Staff

If, in days past, you have questioned why hard piping was used for mechanical seal flush lines and seal support configurations in process pumps, you are certainly not alone.

Reliability: Include pump wear rings in your upgrade efforts

Bloch, Heinz P., Hydrocarbon Processing Staff

Most centrifugal pump designs include replaceable rotating wear rings on the impeller (impeller wear rings) and stationary wear rings inside the casing (case wear rings). Although pump wear rings are simple components, they can have profound impacts on pump reliability, efficiency and safety. These wear rings serve three purposes:

Reliability: Dry gas sealing technology replaces segmented carbon rings in small steam turbines

Bloch, Heinz P., Hydrocarbon Processing Staff

Since the late 1800s, small steam turbines have incorporated bushing-type, single-piece and/or segmented carbon gland components to reduce and prevent steam leakage along the shaft.

Reliability: Deriving high value from reliability conferences

Bloch, Heinz P., Hydrocarbon Processing Staff

In August 2017, a publisher-colleague and I attended an important regional reliability conference in Galveston, Texas.

Reliability: Could a company be its own worst enemy?

Bloch, Heinz P., Hydrocarbon Processing Staff

In a recent conversation with a “pump veteran,” we explored his 33 yr of experience with pump original equipment manufacturers (OEMs) from 1984–1997 and with a widely known non-OEM (1997–2017).

Reliability: Technology transfer training is most effective for small groups

Bloch, Heinz P., Hydrocarbon Processing Staff

Training can take many different forms.

Reliability: Choices—Treat the symptom or define and eliminate the cause?

Bloch, Heinz P., Hydrocarbon Processing Staff

In an urgent communication, a paper plant customer reported that the mechanical seals in one of its ANSI pumps were moving axially whenever an unexpected process problem caused the normally liquid pumpage to turn into a thick, odorous gel.
