    Common use cases for corrosion wax tape?

    Not exactly sure what you mean by wax tape but yes, coat the line with epoxy and irregular shapes you can use the wax tape, whether that be the old Denso mastic and tape, or the newer viscoelastic mastics and overcoat. Don't put it over welds, use the 2 part epoxy for those, valves you can also...

    Gas terminal piping integrity assessment

    1) yes you can do two things, provide a cut out section of material and send to the lab for standard testing (which is often difficult to obtain given it is in service) this is the best option, option two is there are portable testers that have come onto the market in the last year thanks to the...

    Leaving The Girth Weld Uncoated in Sour Gas Pipeline

    With proper inhibition I don't see this as a huge issue, but you will get some corrosion at the girth welds eventually. The large cathode to anode scenario isn't really valid (at least until the coating starts to break down). There is going to be some edge affect where the coating stops, being...

    IN LINE INSPECTION COMPANY COMPARISON

    The question is a very broad question to answer. It depends what type of service offering you want. There are differences in technology or application of technology between the companies. Some may specialize in ultrasonic tools, some in MFL tools, some in EMAT tools, some in geometry/caliper...

    How to solve this issue in accordance with the ASME B31.3 standard - Pipe seams continuously weld

    You mean welds are not offset on ow different joints? There is still a girth weld in between them, they are not continuous... Not a big issue.

    Fusion bonded epoxy coating permittable repairs for line pipe

    I'm probably too late, not sure how that left the coating mill, or the inspectors allowed it. Perhaps the holidays were caused from handling/transport. you can repair it in the field with a two part epoxy in the field, there are many available (from Denso, SPCC, etc.), follow their specification...

    FFS Dent in Stainless Spool

    API 1183, ASME B318 App R, to name a couple... there are many. These are related to gas/oil transmission pipelines, but the same principles apply for other pipelines. No idea of your service, so I can't comment on consideration of other factors you may want to consider

    Piping out of roundness

    Repair or replace. Not sure what service this is in, but even if you inspect it now and find no anomalies in it, some can develop over time (again, depending on service conditions). Numerous acceptance criteria exist in the pipeline integrity world for dents (size in terms on depth diameter...

    Stainless Steel Pipeline- CSA Z 662-2019

    Section 5.1 of Z662 has a bit more, it does not exclude it, but generally states you need to do your due diligence to use it. Yes on 72% max design. A268/A268M-10 Standard Specification for Seamless and Welded Ferritic and Martensitic Stainless Steel Tubing for General Service

    Need to Paint a Pipe - SSPC Spec? and Paint Type

    There's no photo. If you are setting up for blast you may as well go to SSPC-10, you'll get it cleaner with a better anchor pattern. Most coatings fail because of inappropriate surface prep. That coating calls for SSPC-10 in immersion service anyway (in its data sheet, you must follow this)...

    RBI % reduction in man-hours

    Nice one Mike!

    RBI % reduction in man-hours

    RBI is about dong the inspections that you should, and not doing the inspections that you don't have to, based on risk factors and equipment history. Approaching it from the how many man hours or cost savings approach isn't the best approach, and you probably won't get the answer you are looking...

    Water Quality for Hydrotesting

    The issue is the way the system operates, not so much the hydrotest water (if those sections were dewaterd and dried properly, yes obviously on the chlorides you need to limit that). But why on earth are they leaving water stagnant for 6 months? Of course you're going to get MIC problems. If...

    Finding Coating defects on burried pipes with local cathodic protection

    Use DCVG and ACVG, it will detect holiday locations in the coating, this is assuming enough current is actually reaching the pipe you can reasonably detect. What are CP levels on this line currently? CIS won't necesarily tell you much as if there is no CP system for this line, you are just...

    Non-Destructive Examination for GRP Piping

    You may be able to use microwave inspection, one inspection name is Evisive. https://www.evisive.com/ several vendors would offer something like this or use this machinery.

    How long does API 5L X52 last transporting sour gas?

    The pipe can potentially last forever if you take into consideration maintenance or apply mitigation, assuming your pipe in manufactured to sour service specifications (NACE, or ensuring hardness levels). I've operated pipelines more sour than that that are >50 years old with no failures. That...

    Pipeline Magnetic Tomography Survey

    Against my better judgment I will answer and have some very limited experience with this (also in Canada). There is a company out of France called Skipper NDT that uses this, and they subcontract through a Canadian company called Global Raymac. I have dealt with them a little, they have some...

    Wax in a pipeline

    If you want to spend money you can try a wax dispersant chemical, that will prevent adhesion to pipe walls, numerous chemical vendors carry these and are quite commonly used. If your pipeline is leading to processing, you will need to complete a compatibility study to ensure the chemical does...

    Welded pipe seams in orientation

    It's listed in the code: AWS D1.1 Structural Welding Code- Steel, 5.22.3.1 Girth Weld Alignment (Tubular), as 90 degrees as standard, which may be the basis for it and people doing it? As for why, your reasoning is the only rationale I've heard for this,to stop very long fractures in brittle...
