The Scraper Passage Indicator, engineered by EMT, is a highly reliable device designed to monitor and confirm the movement of pipeline pigs through various sections of a pipeline. Commonly installed at critical points such as pig launching and receiving stations, this indicator plays a vital role in ensuring the operational integrity and efficiency of pipeline maintenance operations.

1. Key Specifications and Features

Material Construction

The Scraper Passage Indicator by EMT is engineered with a variety of high-grade materials, each selected to provide optimal performance in different pipeline environments. The available materials include:

• Stainless Steel 304. Known for its excellent corrosion resistance and durability, ideal for water and less corrosive substances.
• Stainless Steel 316.. Offers enhanced corrosion resistance against more chemically aggressive environments compared to 304, suitable for marine and industrial applications.
• DSS F51 (Duplex Stainless Steel). Combines the benefits of austenitic and ferritic stainless steel, providing high strength and exceptional resistance to corrosion, particularly stress corrosion cracking.
• Carbon Steel A105N. Features good machinability and impact strength, suitable for moderate to high-temperature services.
• Inconel 625. A nickel-chromium-molybdenum alloy known for its high strength, outstanding corrosion resistance, and ability to withstand extreme environments, including high temperature and pressure.

These material choices ensure that the Scraper Passage Indicator can withstand harsh operating conditions, offering high resistance to wear and corrosion, thereby extending the device’s operational life significantly.

Design and Functionality

a. Trigger Types:

• Bi-directional. Allows detection of pigs traveling in both directions, enhancing operational flexibility.
• Bi-directional Feather. Features a more sensitive detection mechanism, ideal for detecting lightweight or foam pigs.
• Uni-directional. Simplifies the system by detecting pigs traveling in a single direction, reducing system complexity and potential for errors.

b. Indicator Types:

• Manual Reset Flag. Provides a simple, visual indication that a pig has passed a certain point in the pipeline.
• Manual Reset Flag with Electrical Switch Output. Integrates with pipeline control systems to provide automated alerts and data logging.
• Digital Display with Electrical Switch Output. Offers precise digital feedback on pig location and status, ideal for complex pipeline networks requiring detailed monitoring.

c. Mounting Options:

• 2-inch Flange Connection. Ensures a secure and leak-proof installation suitable for high-pressure applications.
• 2-inch Welded Nipple. Provides a robust connection for permanent installations.
• 2-inch Welded Base-NPT Nipple Connection. Offers versatility for easy installation and maintenance in various pipeline configurations.

d. Performance Attributes

• Operating Temperature Range. -20°C to +120°C, allowing the device to function effectively in a broad range of environmental conditions, from arctic cold to desert heat.
• Pressure Rating. Capable of handling up to ANSI 2500# / API 10,000 Psi, this indicator is designed for high-pressure pipeline applications, ensuring reliability and safety under extreme conditions.

e. Customizable Features

EMT supports extensive customization options through OEM, ODM, and OBM services to meet specific client requirements. This flexibility allows clients to request modifications in design, functionality, and material composition to align perfectly with their unique operational needs.
