PRESSURE GAUGE ACCESSORIES
Kriloha Gaskets, a leader in high-performance sealing and instrumentation hardware, offers an expansive range of Pressure Gauge Accessories. Integrated within our Valve and Fitting Accessories line, these components are engineered to shield sensitive instruments from the harsh realities of industrial processes—be it extreme temperature, pulsating pressure, or corrosive media.
Catagories
The Necessity of Gauge Protection
Pressure gauges are precision instruments, often featuring delicate internal components like Bourdon tubes or diaphragms. When exposed directly to raw process conditions, these elements are prone to:
Thermal Damage: High-temperature steam or vapors can deform internal links.
Mechanical Fatigue: Rapid pressure fluctuations from pumps or compressors can “whip” the pointer and wear out the movement.
Overpressure Surges: Unexpected spikes can permanently calibrate a gauge or cause a rupture.
Kriloha Gaskets’ accessories act as a “buffer zone,” ensuring the gauge “sees” the pressure without suffering from the environment.
Technical Specifications and Material Science
At Kriloha, we utilize our metallurgical expertise to ensure our accessories survive where others fail.
Material Selection:
Stainless Steel (316/316L): The primary choice for offshore, chemical, and pharmaceutical applications due to its superior corrosion resistance.
Carbon Steel (A105): A robust, cost-effective solution for high-pressure oil and hydraulic systems.
Monel, Inconel, and Hastelloy: For specialized service involving sour gas (H2S), hydrofluoric acid, or extreme temperatures.
Design Compliance:
Our accessories are designed in accordance with ASME B40.100 and ASME B1.20.1 (NPT), ensuring seamless compatibility with standard industrial instrumentation setups globally.
Key Categories of Pressure Gauge Accessories
1. Gauge Siphons (Pigtail & U-Type)
Siphons are the essential thermal barrier for steam service.
How they work: The coil (pigtail) or U-bend traps condensate, which acts as a cool liquid barrier between the hot steam and the gauge.
Types: Pigtail Siphons for horizontal pipelines and U-Type Siphons for vertical lines.
Kriloha Benefit: Our siphons are manufactured from seamless pipe with high-integrity welds to ensure zero leakage at the pressure boundary.
2. Pressure Gauge Snubbers (Pulsation Dampeners)
Snubbers protect gauges from the “chatter” caused by reciprocating pumps and compressors.
Types: Porous-type (best for gases), Piston-type (self-cleaning for liquids), and Adjustable-type (external needle valve for fine-tuning).
Impact: They smooth out pressure peaks, making the gauge easy to read and extending the life of the internal gears.
3. Gauge Savers (Overpressure Protectors)
These are “safety fuses” for your instrumentation.
Function: A spring-loaded piston automatically closes the flow path if the process pressure exceeds a pre-set limit.
Application: Ideal for systems with unpredictable pressure spikes or for protecting low-pressure gauges in high-pressure networks.
4. Gauge Cocks and Manifolds
These provide the “Block and Bleed” functionality required for safe maintenance.
Gauge Cocks: Simple 2-way or 3-way isolation valves.
2-Valve Manifolds: Allow for isolation and the safe venting of trapped pressure before gauge removal.
Why Choose Kriloha Gaskets?
While many provide fittings, Kriloha Gaskets provides instrumentation security.
1. Total Sealing Integrity
As experts in the “Science of Sealing,” we ensure that every accessory—from the NPT threads to the internal poppets—is optimized for leak-free performance. Our accessories are designed to work perfectly with Kriloha Thread Sealants and Teflon Tapes.
2. High-Pressure Capability
Our forged series of snubbers and gauge savers are rated for up to 10,000 PSI, providing a safety margin that far exceeds standard commercial-grade fittings.
3. Custom Engineering
Whether you need a specialized “Mini-Siphon” for tight spaces or a NACE-compliant snubber for sour service, our engineering team can provide customized solutions that meet your specific GEO-location and project requirements.
Available Profile Configurations
Installation and Maintenance Best Practices
Filling the Siphon: Before commissioning a steam system, always pre-fill the siphon with water. This ensures the “condensate seal” is present from the first second of operation.
Snubber Cleaning: If a snubber becomes clogged, our piston-type models can be easily disassembled and cleaned without needing replacement.
Gasket Matching: When mounting flanged gauge accessories, always use a fresh Kriloha Spiral Wound Gasket to ensure the primary pressure seal is maintained.
Frequently Asked Questions (FAQ's)
Q: When do I need a siphon versus a simple pipe extension?
A: If your process temperature exceeds 60°C (140°F), a siphon is mandatory. A simple extension does not trap the condensate required to protect the gauge from hot vapors.
Q: Can I use an adjustable snubber for both liquid and gas?
A: Yes. Adjustable snubbers are highly versatile as they allow you to manually tune the damping effect regardless of the viscosity of the media.
Q: What is the benefit of a 3-way Gauge Cock?
A:A 3-way cock allows you to isolate the gauge from the process and simultaneously vent the pressure to the atmosphere, allowing for safe removal or zero-point calibration.
Q:Do Kriloha Gauge Savers require manual resetting?
A: No. Most of our gauge savers are designed to automatically reopen once the system pressure falls below the set safety limit, ensuring continuous monitoring without operator intervention.
Q: Are these accessories compatible with "Oxygen Service"?
A: Yes. We offer specialized “Degreased for Oxygen” versions that are cleaned and packaged in a controlled environment to ensure zero hydrocarbon contamination.
