Adhesion performance is required for every coating system. The adhesion between coatings and substrates is one of the most critical determining factors in the overall success of any coating material. Material design and formulation are key components of high-performance coatings and rely heavily on the accurate measurement and evaluation of adhesion in the coating systems.

In June of 2006 the South Coast Air Quality Management District (SCAQMD) implemented new volatile organic compound (VOC) requirements for industrial maintenance coatings. Two years prior to this date The California Department of Transportation started looking for a replacement latex resin that would meet these new requirements and still have the same properties as currently used industrial maintenance bridge coatings.

Formulation Guidelines for the use of Zinc Flakes in Heavy Duty Corrosion Protection Complying with SSPC Paint 29 Requirements

Product Number: 51323-19533-SG

Publication Date: 2023

For many years, sacrificial corrosion protective paint formulations based on Zinc consisted of zinc dust at approximate 80% loading and about 10% epoxy binder. This composition is necessary for corrosion protection, as direct zinc to zinc dust contact is only possible at high zinc dust loadings. This goes back to the spherical shape of the zinc dust particles with their low surface area.

Formulation Of Novel Combination Production Chemicals For Deepwater Oil And Gas Fields

Hydrocarbon production currently occurs in a variety of onshore and offshore locations. Most offshore production in shallow water (< 500 m) has reached maturity, with most of the more accessible reserves having already been exploited. As a result, exploration and production in offshore environments has been extended to deeper water (> 500 m), which usually incurs more expense and overall project risk for operators and service providers. Production from deepwater oil fields is expected to grow by 40%, to 10 million bpd (10% of total global output), by 2025.

Formulators in the Field: The Effect of Over-Cure or Under-Cure of Polyclamine Cured Epoxy Linings

Product Number: 41216-993-SG

Publication Date: 2016

Advanced technology high performance tank linings are often applied by plural spray equipment and occasionally one of the components could be off ratio. Worse still, some well-intentioned field personnel might add more curing agent to speed up the cure, or alter other properties, or may not utilize the entire curing agent portion in a single leg application. This paper investigates the effects of under-cure or over-cure on the performance of two high temperature tank linings by deliberately mis-mixing the two components.

Fouling, Corrosion, And Wear Protection Of Power Take Off Rods For Wave Energy Conversion - Laser Cladding And Scraping

Harvesting ocean energy will play an important role in supplying fossil-free energy for future generations. The oceanic environments around the world are unfortunately of the toughest possible to operate in. Most technologies use a power take-off (PTO) unit with mechanisms that are placed inside protective enclosures or sealed buoys to protect from the harsh environment in seawater. This gives a barrier from the corrosive electrolyte and biological activity that can deteriorate the components. The energy from the oceans in form of relative movements and forces are transferred to the PTOs with help from complex dynamic sealing systems.

Fracture Failure Analysis of Type HL Sucker Rod in H2S-CO2 Environment

Recently, there have been several cracking failures of type HL carbon steel sucker rods with evidence of fatigue striation. In order to find out the reason for the fracture failure, the fracture morphology, material properties, loading and corrosion product of the failed type HL 35CrMoA sucker rod were analyzed, combined with the corrosion environment. The results show that the material properties of the failed 35CrMoA sucker rod meet the GB/T 26075-2010 standard requirements. Also the result of loading analysis shows that the loading is far from the fatigue limit stress. The type HL sucker rod’s yield strength is almost 1049 MPa and hardness is 35.2 HRC. In addition, the low in-situ pH and high H2S-CO2 partial pressure places the sucker rods in the Region 3 of sulfide stress corrosion cracking, which means the quenched and tempered sucker rod’s yield strength should not exceed 863 MPa and hardness should not exceed 30 HRC, according to the ISO 15156-2:2015 standard. It is concluded that the high hardness level of the type HL sucker rod led to sulfide stress corrosion cracking in the high H2S-CO2 partial pressure and low in-situ pH condition.

Fracture Toughness Evaluation of Precipitation Hardened Nickel Alloys Under Cathodic Polarization Environments

Product Number: 51319-12849-SG

Publication Date: 2019

There is a significant use of Nickel based alloys in the oil and gas industry for high strength / high corrosion resistance applications yet there has been a lack of understanding of fracture toughness of these Ni alloys under seawater / Cathodic Protection (CP) environments. Furthermore this class of alloys has demonstrated a weakness following high profile failures where the failing mechanism identified was Hydrogen Assisted Cracking (HAC). This study examines several Precipitation Hardened (PH) Nickel alloys by the J-R Curve method (ASTM E1820) using side-grooved single edged notched bend (SENB) fatigue pre-cracked test samples in a simulated seawater environment under CP. The Ni alloys evaluated a good representation of those associated with the in-service failures reported in the past were UNS N07718 UNS N07716 and UNS N07725 together with other alloys more recently developed such as UNS N09945 and UNS N09955.The materials were tested in a 3.5%NaCl solution with applied potentials of -1.1V and -1.4V vs SCE at room temperature at a loading rate of 0.005 Nmm-3/2. The overall response of the alloys in laboratory air was elastic-plastic in nature while the behavior in environment shifted towards a linear-elastic response most likely associated with the embrittlement caused by the hydrogen adsorbed during CP. Scanning electron microscopy analysis was performed to obtain insights on the fracture morphologies. Amongst the alloys tested UNS N07718 showed the least reduction in fracture toughness in the environment in relation to air while alloy UNS N07716 showed the most susceptibility to the environment with the lowest performance.Key words: Ni Alloys Fracture Toughness J-R Curve Method CP environment seawater.

Fracture Toughness of 41XX Cr-Mo Steel, Super Martensitic Stainless Steel and Nickel Alloy in High Pressure Hydrogen Environment

Product Number: 51324-21083-SG

Hydrogen is considered one of the options to be used as alternate fuel source to reduce carbon emissions. Towards this there is growing interest in using underground storage for hydrogen gas (H2) which can be stored in larger volumes, higher pressure than surface storage options would allow for. While underground well storage of natural gas is widely understood; there is far less experience in storing H2 only or H2 in blend with natural gas. An area of knowledge gap is the compatibility of metallic materials that need to be used for well construction for underground storage as the assessment of risk for Hydrogen Embrittlement (HE) would need to be addressed. In this work, some of the common materials used in well construction for various oil and gas wells, i.e., high strength quenched and tempered 41XX type Cr-Mo steel, Super Martensitic Stainless Steel (Super 13Cr) and Age Hardenable Nickel alloy grade Alloy 925 (UNS N09925) all with similar yield strength levels have been assessed for compatibility with high pressure H2 gas. Evaluation was mainly performed via Fracture Toughness testing in both inert and high pressure H2 gas environment per ASTM E1820.1 Details of this assessment and post testing evaluation of the specimens will be provided in this paper.
