Marine and Shipbuilding Instrumentation

-- Steady & Reliable Manufacturer --

Brief Description

Marine and Shipbuilding Instrumentation is designed and certified to withstand the unique rigors of the maritime environment, including constant vibration, high humidity, salt spray, and extreme temperature variations.

In-depth Overview

Ships and offshore vessels require instruments with superior durability and specific certifications (DNV, ABS, Lloyd’s Register). This includes robust, stainless steel SS316 casings for corrosion resistance, liquid-filled gauges for vibration dampening, and high-quality bi-metal or glass thermometers for engine and piping systems. Special attention is paid to shock resistance and fire safety compliance. Our range ensures reliable pressure and temperature data for engine management, ballast systems, and cargo monitoring.

Applications

Main Engine Room: Monitoring lube oil pressure, fuel pressure, exhaust gas temperature, and cooling water.
Cargo Handling: Pressure monitoring for pumps and pipelines on chemical and oil tankers.
Ballast Water Management: DP and level sensors for critical tank stability control.
Boiler Systems: Temperature and pressure control in ship's steam generation units.

Key Advantages

Type Approved: Certified for use by leading marine classification societies, simplifying vessel certification.
Salt Water Resilience: SS316 construction and specialized seals resist corrosion from salt spray and maritime air.
Shock and Vibration Tolerance: Designed specifically to maintain accuracy under continuous engine vibration.
Long-Term Reliability: Built for minimal maintenance in harsh, continuous operational cycles.

Payment and Shipping

We accept T/T and L/C. Marine instruments often require specific factory tests and classification society witness inspections; lead times can range from 4 to 8 weeks. We provide robust export packaging, ensuring that all delicate components, such as capillary lines or glass thermometers, are protected against the high shocks encountered during sea freight and port handling.

Frequently Asked Questions

Q: Why is SS316 mandatory for marine applications?
A: SS316 has higher resistance to chloride corrosion than SS304 due to the addition of molybdenum. This is vital in a marine environment where instruments are constantly exposed to salt and humidity, preventing pitting and premature failure.

Q: What are the main requirements for a marine-approved gauge?
A: Marine approval requires documented resistance to vibration, shock, fire (in some areas), and electromagnetic compatibility (EMC). The instrument must function reliably within the specified ambient and operational limits set by the relevant classification society.

Q: Can I use a standard industrial gauge on a ship?
A: No. Using non-approved instruments can lead to failure, inaccuracy, and may violate regulatory codes, potentially resulting in the vessel being held up or failing mandatory inspections. Always use certified marine-grade instruments.
