... detection technology we developed used complex instrumentation which required highly trained personnel and a lab environment to conduct testing. The technology has since undergone significant development and now consists of a small, rugged instrument, easy-to-use method and the ability to be deployed...

.... This paper explores the current state of the art for the increased temperature limits of high density polyethylene liners and identifies the most credible failure modes to be mitigated. A testing campaign was conducted on commercial grade high density polyethylene to de-risk the application of the liners...

... and costs associated with more sophisticated techniques (e.g., HPHT autoclave or flow loop tests) may restrict use of such tests to chemicals at dose rates pre-qualified from simpler screening tests. This paper provides illustrative examples of how seemingly small changes to test methodology...

...Abstract Various Laboratory test procedures have been used to develop profiles and models of minimum effective dosage as a function of water chemistry, temperature and time. Some procedures provide realistic data, directly applicable to operating systems. Others that have been used and published...

...Test Criteria ASTM D6041 (Section 7) requires that Fittings and Joints be pressure tested using ambient temperature water to four times the rated pressure (4 x 290 psi (20 Bar) = 1160 psi (80 Bar)) for one hour without leakage. ASTM D5421 requires flanges to be pressure tested for one week at one...

... MR0175 is 20 kPa (3 psi) H₂S. Previously published data established that UNS S33207 passed C-ring testing at 90°C with 3 psi H₂S. However, the limit for UNS S33207 performances in a sour environment was not defined and the aim of this work is to investigate how UNS S33207 performs...

... in the solution. When failures occurred it was often found in the fusion line between weld metal and Heat Affected Zone (HAZ). This work formed also the basis for safety factors on the H₂S content in the testing. The safety factor used since then has been 2 on the partial pressure. Test environment...

...Corrosion testing Inhibited ferric chloride test Corrosion testing was performed on welded samples and base material in an inhibited ferric chloride solution comprising 5 wt% FeCl₃ + 1 wt% NaNO₃ according to ASTM A1084 Method C. ⁶ The samples were cut...

... conditions which can arise with increasing combustion or co-combustion of biomass and waste have been less thoroughly investigated. In this paper results are presented from laboratory tests designed to simulate the corrosive conditions in flue gas cleaning systems and based on analysis of actual condensate...

...This paper points out the necessity of testing in conditions as close as possible to the actual service situation, with the aim of obtaining helpful data for materials performance in extreme conditions. Abstract The exploitation of fields with high H₂S and/or CO₂ content...

... presented an overview of different methods currently being used in the oil and gas industry to test UDC, and a summary of mitigation methods used to control this type of corrosion. ⁸ There is a general consensus on the mitigation techniques that are effective in controlling UDC, which include...

... qualification testing of butt welded DNV SML 13CR-2.5MO grade 13%Cr steel pipes, for use in a subsea flowline project. Welds were manufactured using a manual GTAW process and a superduplex stainless steel consumable, which were then subjected to a plastic straining cycle to simulate reeling, the preferred...

... for nuclear service. Some of these are listed in Table 1 . Abstract Intergranular corrosion tests such as ASTM G28, Practices A and E and RCC-M MC1300 are often used to verify the resistance of nickel alloys to intergranular corrosion. The inherent differences in wrought products and weld metals can cause...

...Abstract K_LIMIT for the NACE Test Method TM0177 - Method D (DCB) has been introduced in a new proposed informative appendix in that document. This paper gives the background to the appendix and explains the definition, measurement and use of K_LIMIT. Some common pitfalls...

...Personal water analytics (PWA) is a new testing platform that can be adapted to numerous tests, but who’s first product is a card designed to test industrial recirculating cooling waters. A survey of industrial cooling water testing was performed to determine the most frequently tested chemical...

... embrittlement behaviour of martensitic carbon steels. Therefore, a series of tests was performed to establish the risk of cracking in a buried condition where cathodic protection is applied. Tests were performed to establish the plateau hydrogen content and the hydrogen flux under various charging conditions...

...Abstract UNS S33207 is a new hyper duplex stainless steel with a minimum PRE of 50 that has been developed for use in umbilicals. Results from corrosion and mechanical testing show that UNS S33207 has better localized corrosion resistance and higher strength than superduplex stainless steel...

...Double-Sided and Temperature Abstract Commercially available steel coiled tubing were exposed to sour environments and tested by full size bending fatigue and laboratory scale testing to simulate operational conditions. This paper builds on previously published test results with new fatigue...
