Bloch, Heinz P.

Hydrocarbon Processing Staff, Montgomery, Texas

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: How application engineers add value

Hydrocarbon Processing Staff: Bloch, Heinz P.

Making the vendor-manufacturer your technology provider has been our consistent advice to the user industries; we have recommended this highly effective approach for many decades.

Reliability: Better pumps and seals for HF service

Hydrocarbon Processing Staff: Bloch, Heinz P.

In mid-2017, we received a well-written request from a young reliability engineer.


Hydrocarbon Processing Staff: Bloch, Heinz P.

With certain turbocompressor designs having changed as manufacturers and user-clients constantly push to increase output and efficiency, it pays to know if—and how—high-performance couplings (HPCs) have kept pace.

Reliability: Consider today’s canned motor pumps

Hydrocarbon Processing Staff: Bloch, Heinz P.

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

Hydrocarbon Processing Staff: Bloch, Heinz P.

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

Reliability: Guidance for a lube sampling program

Hydrocarbon Processing Staff: Bloch, Heinz P.

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

Reliability: Consider stainless steel tubing for mechanical seal connections

Hydrocarbon Processing Staff: Bloch, Heinz P.

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

Hydrocarbon Processing Staff: Bloch, Heinz P.

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

Hydrocarbon Processing Staff: Bloch, Heinz P.

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

Hydrocarbon Processing Staff: Bloch, Heinz P.

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