nttファイナンスから請求書がきましたが全く身に覚えがなくて詐欺かな思い調べても乗ってる情報はすべて正しいんから詐欺ではなくて請求書の内容が通信料等なんですがほんと身に覚えがなく通信料等とは例えばどんなことで請求書されるか教えてほしいです。
UT and RT can also be useful equipment, but their Main position should be that of regime inspections and integrity assessments considering that they do not provide sensitivities for detecting corrosive disorders that are akin to those of corrosion coupons or Digital probes placed inside the devices.

ER probes are extremely worthwhile instruments for measuring internal corrosion charges while not having to bodily take away the sensing aspect from the method stream. The corrosion Handle professional can basically head over to The situation in the ER probe and make an electronic relationship towards the probe or remote knowledge logger, and record or obtain the info, which would then be taken to an office for evaluating the corrosion rate developments.
Corrosion coupons are an easy and cheap way to shield your costly HVAC or system parts. There is certainly an upfront cost to set up the rack, along with the lab analyses might or might not be coated inside your support contract (Speak to your water cure supplier in case you’re unsure) – but these are definitely small expenses when put next to the price of possessing to interchange corroded equipment, or maybe to perform a cleaning.
That may be 2 yrs before we could detect and ensure the corrosion working with RT or UT methods. We Observe that any metal, which can be missing through the pipe wall during that point, can not be put again onto the pipeline, and undetected corrosion can shorten the helpful company lifetime of pipelines.
Online checking: Refers to set up of checking equipment for continuous measurement of metallic decline, corrosion level, or other parameters in an working process; details are acquired devoid of eliminating the monitoring device.
A 2nd position is always that for initially creating the expected chemical treatment prices, we relied on benefits from ER probes within the pipeline—not metallic coupons. As described in Part 28.2.two, ER probes are certainly delicate, and readings can be gathered at limited intervals, which include hourly or each day with no removing the ER probes through the pipeline. In distinction, metal coupons are remaining inside the pipelines for for a longer period more info intervals, for instance ninety days.

(Another option for pipeline and corrosion engineers to think about is lowering the MAOP for the part of pipe. That would cut back the portion of the pipe wall thickness expected for strain containment, but would raise the portion of the pipe wall thickness to the corrosion allowance. Nevertheless, this feature must only be made use of incredibly judiciously.)
The numerical value next the letter designation signifies the relative thickness of the sensing component, which indirectly delivers the effective provider life time from the probe.
You will also find developing technologies that are only currently being introduced in 2013, which use laser or three-dimensional structured mild to profile pits. These new pit depth/profile systems are envisioned to become extra extensively used in long term apps due to the diminished time necessary for each assessment [16].

Once the coupons are produced, These are marked with a novel serial amount for identification and traceability. Coupons must have a dependable finish, free of defects to supply reliable data.
