One of the parameters that determine the contact conditions of sucker rod operation and therefore the severity of the damage is the coupling roughness. In the present work, we investigate the impact of coupling roughness on friction and tubing damage.

AMPP SP21513-2021, Procedure for Determining Conformance to Concrete Surface Profile Requirements

Product Number: AMPP SP21513-2021

Publication Date: 2021

$109.00

This standard describes a procedure suitable for laboratory and field use to determine conformance to specified surface profile on concrete substrates using Method 1: Depth micrometer as described in ASTM D8271, Method 2: Concrete Surface Profile (CSP) Chips (CSP 1-10) as described in ICRI Guideline No. 310.2R, or Method 3: Replica putty as described in ASTM D7682 (Method 3A-visual or Method 3B-quantitative).

Proper bonding of coatings and linings to concrete surfaces requires proper cleaning and frequently requires the concrete to be roughened to increase the surface area. The roughness, also known as surface profile, can be imparted into concrete by abrasive or water blast cleaning, acid etching or various impact/scarifying power tools. The resulting surface profile depth can influence coating/lining adhesion and performance. Coating/lining manufacturers and/or facility owners frequently specify cleaning and roughening of the concrete surface prior to product installation.

Effect Of Steel Surface Profile Peak Density On Rust Creepage

Product Number: 51322-17584-SG

Author: Russell Draper, Michael Beamish

Publication Date: 2022

$20.00

The spread of disbondment or corrosion from a scribe or holiday in a coating film, for which the terms rust creepage or undercutting are used in this paper is an important mechanism of coating degradation. The mechanism of rust creepage has been well studied by several authors who concur that the mechanism is driven by electrochemical reactions15. The reactions occurring at the discontinuity in the coating (scribe or holiday) involve an anodic reaction in which iron is dissolved. Adjacent to the anodic region, under the coating, a cathodic reaction occurs in which oxygen is reduced to hydroxyl ions.

NACE SP0616-2022, Standard for Hull Roughness Measurements on Ship Hulls in Dry Dock

Product Number: NACE SP0616-2022

Publication Date: 2022

$109.00

This standard practice provides a standardized method of measuring hull roughness to enable reproducible and comparable readings from similar gauges regardless of geographical location.

One of the factors affecting a ship's performance and fuel consumption is the roughness of its foul-free underwater hull. the Condition and type of paint system used may have a major influence on hull roughness and ship performance. Hull roughness has a major impact on vessel fuel efficiency and exhaust emissions. This standard focuses on the mechanical roughness of the hull.

Surface Comparison Profile - A Comparison of Measurement Methods

Product Number: 41213-731-SG

Author: David Beamish

Publication Date: 2013

$20.00

Coating performance is related to the profile height on a steel surface. Three types of devices are available to take measurements of this surface profile: replica tape, depth micrometers fitted with pointed probes, and stylus roughness testers. This paper presents results from a recent analysis of measurements taken by the three device types on steel blasted with an assortment of blast media and proposes a new method of depth micrometer measurement called average of the maximum peaks.
