Product Overview
The JIECHUANG YB Series Dual Scale High Pressure Gauge is engineered specifically for local pressure indication in extreme, high-stress industrial environments. Featuring a heavy-duty stainless steel construction and a dual-scale dial (MPa/PSI), this gauge allows operators to monitor critical system pressure instantly without manual conversion.
Designed to withstand severe operating conditions, it is the premier choice for offshore platforms, wellhead control panels, and ultra-high-pressure hydraulic systems.
Typical Applications
Oil & Gas Exploration:
Offshore drilling platforms, Christmas trees, and high-pressure manifolds.
Wellhead Control Panels (WCP):
Hydraulic control systems requiring high-integrity safety monitoring.
Hydraulic Power Units (HPUs):
Industrial ultra-high-pressure hydraulic systems and test benches.
High-Pressure Pumping & Testing:
Hydrostatic test pumps, chemical injection skids, and fracking equipment.
Key Features and Benefits
High-Pressure Precision:
Optimized for extreme hydraulic and process setups, offering standard full-scale ranges up to 100 MPa / 15,000 PSI.
Advanced C&T Connection:
Utilizes a Cone and Thread (C&T) high-pressure connection to achieve a reliable, high-stress metal-to-metal seal without soft gaskets.
Dual-Scale Visibility:
Standard dual-unit dial displays MPa (inner/black) and PSI (outer/red) for seamless global compatibility.
Rugged All-Stainless Steel Construction:
Engineered with a 316/304 Stainless Steel case and wetted parts to deliver exceptional corrosion resistance in harsh offshore and marine environments.
Enhanced Readability:
Available in a 150 mm (6”) dial diameter, ensuring clear, long-distance readability on crowded control panels.

Configuration and Selection
When requesting a quotation, please specify:
Required pressure range and pressure units
Dial diameter
Process connection standard, size, and sealing type
Process medium and wetted-material requirements
Maximum normal operating pressure and pressure fluctuations
Operating temperature and installation environment
Required accuracy and calibration documentation
For high-pressure service, confirm the allowable working pressure and connection rating before installation. Cone & Thread connections should only be specified when the instrument is supplied with the corresponding compatible connection design.
FAQ
Q1: What makes the Cone & Thread (C&T) connection better than standard NPT threads?
A: For ultra-high pressure applications (above 10,000 PSI), standard tapered threads like NPT are prone to leakage and thread galling. The C&T connection utilizes a machined cone and collar that forces a metal-to-metal hard seal, which remains completely bubble-tight even under extreme stress and pressure fluctuations.
Q2: Is this gauge suitable for offshore corrosive environments?
A: Yes. The entire housing and critical components are made of premium stainless steel, providing excellent resistance to salt spray, moisture, and aggressive atmospheric conditions typical of marine and offshore platforms.
Q3: Can I get customized pressure scales or different connection sizes?
A: Absolutely. JIECHUANG offers tailored solutions including custom scale markings, alternative engineering units, and specific high-pressure thread dimensions based on your blueprint requirements.
