Versatile Construction and Material OptionsGauge Hatches come in a variety of durable materials such as aluminium, stainless steel (SS304/316), and cast iron. Available in sizes from 2" to 12", with custom sizes upon request, and finishes like shot blasted and painted, natural, or epoxy coated. This ensures compatibility with a broad spectrum of storage tank applications and environments, offering excellent corrosion resistance and long service life.
Reliable Safety and Security FeaturesEquipped with solid locking mechanisms, gauge hatches offer padlock facilities for enhanced safety and protection against unauthorized access. The high-integrity, gas-tight design ensures leak-proof sealing, while optional explosion-proof build meets the strictest industrial safety standards, making these hatches suitable for use with volatile or hazardous products.
Manual Operation & Application EfficiencyGauge Hatches operate manually with either a handwheel or a quick release cam mechanism, making them simple and efficient to use. Their spring-loaded or clamp-type structure allows easy and quick access for tank monitoring, sampling, and gauging, ensuring routine operations can be conducted safely and conveniently even in demanding industrial environments.
FAQ's of Gauge Hatches:
Q: How are gauge hatches installed on storage tanks?
A: Gauge hatches are typically mounted on the top of storage tanks using flanged or screwed (BSP/NPT) connections. The installation requires attaching the hatch securely to a prepared tank flange to ensure proper alignment and a firm, leak-proof fit.
Q: What is the primary function of a gauge hatch in industrial applications?
A: Gauge hatches are designed to provide controlled access to storage tanks for level measurement, sampling, and product gauging. They facilitate safe, easy manual operations without compromising the tank's gas-tight seal or structural integrity.
Q: Which gasket materials are available and how do I select the appropriate one?
A: Gauge hatches can be fitted with PTFE, Viton, Neoprene, Nitrile, or Silicon gaskets. The choice depends on the stored media's chemical compatibility, temperature range, and sealing requirements. For aggressive chemicals, PTFE and Viton are often preferred.
Q: Where can these gauge hatches be used, and for what products?
A: These gauge hatches are suitable for industries storing liquids, chemicals, and petroleum products. Their corrosion-resistant and leak-proof design makes them ideal for refineries, chemical plants, and storage facilities handling flammable or hazardous substances.
Q: What safety features are included in these gauge hatches?
A: For safety, gauge hatches offer a padlock facility to prevent unauthorized access. High-integrity sealing and optional explosion-proof construction safeguard against leaks and ensure operational safety in hazardous environments.
Q: How does the operating mechanism work on these hatches?
A: The hatches feature a hinged cover with a handwheel or quick release cam, allowing for fast and simple manual access. Some models include a spring-loaded or clamp-type design for secure closure and quick opening, streamlining routine measurement or sampling processes.
Q: What benefits do gauge hatches provide compared to standard access points?
A: Gauge hatches offer quick opening, gas-tight sealing, easy manual operation, and flexible mounting. Their robust locking and sealing features ensure product integrity and worker safety, making them superior to standard access points for tank maintenance and monitoring.
