Introduction

A precise evaluation of corrosion rates in any surroundings is significant in terms of the cost of maintenance and repair as an outcome of material failure. Crystal Industrial’s Corrosion coupons from India give an affordable method to observe and measure the corrosion inside a system. By observing the mils-per-year corrosion rate of an uncovered coupon, important information can be given related to the material’s life expectancy.

Crystal Industrial’s Corrosion coupons from India have truly fulfilled this requirement well, and have been the regular observing instruments for plant supervisors, engineers, corrosion experts and water treatment organizations. However, in spite of the fact that this sort of observing is easy and straightforward, errors will occur that may render low quality (or even useless) coupon corrosion data. With regards to corrosion coupons, detailed observation can’t be overemphasized, especially when those coupons correspond to real parts/structures.

Besides, the dependence on corrosion coupons as the only testing method is very unsafe. At times, a complete conviction and trust in the data given by corrosion coupon examination has resulted in years of runaway corrosion activity to destruct materials or structures surpassing the scope of repair—and at a tremendous financial cost.

What Is a Corrosion Coupon?

A corrosion coupon is a bit of metal of a preset shape, size and region. It is a metal of chemical composition that can be compared to the technique of instrumentation and has a uniform surface finish and a unique serial number. It is presented to a corrosive medium which is like the structures that it’s made to represent, and hence gives a visual sign of the type of corrosion that may happen, and the rate at which it’s happening. As such, Crystal Industrial’s Corrosion coupons from India are a simple and powerful instrument for giving a quantitative estimation of corrosion rates happening in an operative system. As a testing device, Crystal Industrial’s Corrosion coupons from India extensively facilitate exact corrosion rate observing in a number of important environments.

Thus, they’re utilized to make projections about:
Repair costs
Upkeep
Estimation of material failure.

Key Characteristics

Singly packed in concealed heavy duty polythene sacks.
Fixing hole as required.

The ASTM D-2688 standard, entitled “Corrosivity of Water in the absence of Heat Transfer (Weight Loss Methods)” gives much valuable data in regards to the corrosion checking of water.

Crystal Industrial’s Corrosion test racks from India are intended to allow simple and affordable observing of corrosion inside water systems. Some portion of the water is deviated from the main stream where it passes over test coupons and is then reverted to the system. Crystal Industrial’s test coupons from India can be withdrawn from the rack without the requirement to shut down the system.

Manufactured as per ASTM standard D-2688, with a stream rate of 0.6 to 1.8m/s. Crystal Industrial’s corrosion coupon test racks have a serpentine shape permitting the water to flow along every coupon from the holder in the same course.

Coupon Specification

Fixing opening as required, edges and bore de burred.
Material Identified.
Serially numbered.
Glass bead blast finish.
Pre-weighed to 0.1mg.
Singly packed in data-front VCI envelope and each concealed in heavy duty polythene bags.
