The data reveals that four out of five coupons are redeemed from traditional print media. According to the 2K18 Coupon Intelligence Report , overall, 94 percent of consumers surveyed said they use coupons. This 4 percent increase from comes as millennials use coupons more often. The report also underscores the value of savings via print and digital media. According to the survey, 93 percent of respondents reported using paper, while 75 percent of consumers said they use paperless coupons. The NCH analysis indicates that free-standing inserts FSI remain the primary distribution channel for coupons, though digital coupons are on the rise.

Factors considered in the interpretation of results obtained from these corrosion coupons are also included for the use of oil and service industry personnel. Shall and must are used to state mandatory requirements. The term should is used to state something good and is recommended but is not mandatory. The term may is used to state something considered optional.

Low Flow Rate Density of Metals General 1.
Oilfield operations include oil-, water-, and gas- handling systems, and drilling fluids. When used in this standard, system denotes a functional unit such as a producing well; flowline and tank battery; water, oil, or gas collection facility; water or gas injection facility; or a gas dehydration or sweetening unit. Corrosion coupon testing consists of the exposure of a small specimen of metal the coupon to an environment of interest for a period of time to determine the reaction of the metal to the environment.
Corrosion coupons are used to evaluate corrosiveness of various systems, to monitor the effectiveness of corrosion- mitigation programs, and to evaluate the suitability of different metals for specific systems and environments. The coupons may be installed in the system itself or in a special test loop or apparatus. Corrosion rates shown by coupons and most other corrosion-monitoring devices seldom duplicate the actual rate of corrosion on the system piping and vessels.
Accurate system corrosion rates can be determined by nondestructive measurement methods or failure frequency curves. Data furnished by corrosion coupons and other types of monitors must be related to system requirements. High corrosion rates on coupons may be used to verify the need for corrective action. If a corrosion-mitigation program is initiated and subsequent coupon data indicate that corrosion has been reduced, the information can be used to approximate the effectiveness of the mitigation program.
This standard does not contain information on monitoring for intergranular corrosion, stress corrosion cracking SCC , or sulfide stress cracking SSC. The latter aspects are discussed elsewhere. Corrosion rate calculations and a typical form for recording data are also included. Coupons are often installed in pairs for simultaneous removal and average mass-loss determination.
Coupons may be used alone but they should be used in conjunction with other monitoring methods such as test nipples, hydrogen probes, galvanic probes, polarization instruments, resistance-type corrosion monitors, chemical analysis of process streams and nondestructive metal thickness measurements, caliper surveys, and corrosion failure records.
They show corrosion that has already occurred. A single coupon cannot be used to determine whether the rate of metal loss was uniform or varying during the exposure period. Information on the change in corrosion rate can be obtained by installing several coupons at one time and removing and evaluating individual coupons at specific short-term intervals.
Other monitoring methods mentioned in Paragraph 1. However, corrosion rates in similar systems e. Additional information can be obtained within a system by varying one exposure parameter at a time e. For example, corrosion rates can be affected by changes in fluid velocity within a system. Corrosion rates can vary dramatically upstream and downstream from the point of entry of a corrodent, such as oxygen.
Processing of Corrosion Coupons 2. The following procedure should be used to prepare coupons for corrosion testing. Coupons should be new; do not reuse coupons after exposure and analysis. Grinding operations must be controlled to avoid high surface temperatures that could change the microstructure of the coupon. It is possible for a coupon or holder to undergo SCC if the conditions in Paragraphs 2. Such stress can result from a combination of 5. Nevertheless, broken pieces of coupons or holders can lodge downstream in valves and interfere with their normal operation.
Coupons formed by stamping are less expensive than machined coupons. Stamped coupons are satisfactory without additional machining for most oilfield monitoring. Because this is seldom practical, other surface finishes are applied. No specific surface finish is absolutely essential but uniformity is very important when data from different sets of coupons are being compared. Coupons may be prepared by grinding smooth with grit paper, by tumbling with loose grit, or blasting with abrasive blasting material.
A consistent finish may be obtained by blasting with glass beads, but glass beads may not remove mill scale or rust. All abrasives should be free of metallic particles. Clean, lint-free cotton gloves or cloths, disposable plastic gloves, coated tongs, or coated tweezers should normally be used. If oils are not present, cleaning with alcohol or acetone should be sufficient.

Winston-Salem, NC, Feb. In , digital Load-to-Card L2C coupons accounted for 1. This marks the fifth consecutive year of double-digit growth in L2C redemption resulting in a compound average growth rate of 34 percent. While total coupon distribution and redemption declined by Of that 80 percent, shoppers specifically reported that:. Despite being time-strapped and over-committed, shoppers are carefully and consistently planning their shopping trips, especially before shopping for groceries.
Corrosion coupons are put in contact with the cooling water and remain for a period of time such as 30, 60 or 90 days. They then are removed and evaluated as to their metal loss.

If there is one thing that has remained constant over the past century of marketing, it s the fact that customers like getting the best deal and incentives when they shop. According to a report from Valassis, nearly 61 percent of consumers are influenced by coupons on their grocery purchases. A more recent analysis from a subsidiary of Valassis shows how coupon use changed over the course of As one would expect, the study showed that a huge amount of coupons were retrieved last year.

Discounts and special offers make it easy to incentivize hesitant shoppers to finally pull the trigger and past purchasers to place their second, third or, even, tenth order. Of course, the smartest stores are selective about how they distribute Ecommerce coupons. Instead of slashing prices across the board, they share exclusive discounts with targeted consumers to secure more sales without compromising overall revenue and profit. While coupons are a clever tool store owners and marketers may use to improve critical KPIs, Ecommerce managers may also be surprised by the effects a simple coupon can have on shoppers. Even the most modest discounts can convince otherwise prudent buyers to splurge. Interestingly enough, a study by Coupons. Paul J.
Coupon collector s problem
One day I looked at the image and thought, "Does the paper hire someone to count the coupons? Is this claim a good estimate of the actual value of all coupons in the paper? What is the exact value of the coupons in today s paper? Furthermore, I wondered about which coupons the image refers to? I call these inserts coupon circulars. There are other interesting statistical questions that you can ask about Sunday coupons, such as "What is the distribution of the values of coupons? To research these questions, I collected data about the coupons in coupon circulars for 12 Sundays in early
In probability theory , the coupon collector s problem describes "collect all coupons and win" contests. It asks the following question: If each box of a brand of cereals contains a coupon, and there are n different types of coupons, what is the probability that more than t boxes need to be bought to collect all n coupons? An alternative statement is: Given n coupons, how many coupons do you expect you need to draw with replacement before having drawn each coupon at least once? Think of T and t i as random variables. By the linearity of expectations we have:. Here H n is the n -th harmonic number. Using the asymptotics of the harmonic numbers, we obtain:.
Corrosion coupons are pre-weighed and measured metal strips which are mounted in a special pipe system called a coupon rack. They are used to estimate the rate of metal corrosion by comparing the initial weight with the weight following 60, 90 or days of exposure to the water in the system.
