Quality Control

Testing Process

Testing procedures are in place from the time raw materials are received at the facility to when the finished conduit is packaged and readied for shipping.

1 Rigorous
Assessments

Every stage from procurement of raw material to final product delivery is examined thoroughly thanks to our team of experts.

2 Intensive Research and Development

Our goal is to continuously improve the quality of our products and innovate with new materials.

We conduct official inspections to improve our quality control systems and best practices in order to deliver the latest in conduit technology.

3 Internal
Audits

Our Testing Includes:

Zinc Thickness Test

Utilizing an ultrasonic thickness gauge meter, we ensure that our zinc coatings are measured and scrutinized for thickness and quality.

This meticulous approach allows us to maintain strict adherence to industry standards, guaranteeing the longevity and durability of the protective layer on our products.

Corrosion Resistance Test

We use salt spray chambers in our in-house laboratory to conduct corrosion resistance tests on our zinc coatings.

By simulating an accelerated, corrosive environment, we ensure our coatings meet our highest standards.

Galvanized Uniformity Test

The copper sulfate test on galvanized steel is a simple method used to detect the presence of uncoated areas or defects in the zinc coating of galvanized steel.

The solution reacts with any uncoated areas or defects in the zinc coating, resulting in the formation of a characteristic copper-colored deposit or stain. This indicates areas where the steel is exposed and vulnerable to corrosion.

Thread Gauge Test

The thread gauge test on conduit involves checking the accuracy of the threads to ensure proper fit and alignment during assembly.

The thread gauge test on conduit is crucial for maintaining the integrity and reliability of connections to couplings and conduit fittings.

Dimensional Test

Dimensional testing is crucial for meeting ANSI (American National Standards Institute) standards because it ensures that manufactured products adhere to specific dimensional requirements outlined in ANSI standards.

By ensuring that products conform to specified dimensions, Rep Materials Co can maintain high-quality standards and minimize the risk of defects or failures.

Degree of Bend Test

A digital angle gauge provides accurate angle measurements using electronic sensors.

On larger segments and elbows, a template or jig is used to ensure consistency and accuracy in bend angles.

Rep Materials is dedicated to ensuring precise bend angles, facilitating efficient and precise field installations.

Production Bend Test

Proper conduit bending is essential for the safe and efficient operation of electrical systems. Inaccurate or poor-quality bends can lead to system inefficiencies, increased maintenance costs, and potential safety hazards.

We employ a mix of standard manual benders and hydraulic benders, carefully chosen based on the conduit’s diameter.

Manual Bend Test

Bending EMT (Electrical Metallic Tubing) conduit with a hand bender is a common technique used in electrical installations to create bends in conduit runs to accommodate changes in direction or elevation.

Rep Materials conducts hand bending tests to verify that our conduit bends smoothly without kinking or cracking, while minimizing ovality to simplify wire pulling.

Ovality Test

Our Ovality Test checks performance and safety of our special radius elbows in 36”, 48”, and 60” sizes.

Special radius elbows undergo Ovality testing to ensure they are free of blockages or sharp bends that could hinder wire installation or damage wires.
