Industrial Venturi Tube

Product Description

Product Specifications & Standards

Aditya Engineering Works supplies Venturi tubes engineered to global standards such as ISO5167, ASMEMFC 3M, AGA, ANSI/AGA 3, and API:

• Sizes: Standard DN50DN1200 (248), with larger custom sizes available
• Beta Ratio: 0.3 to 0.75, tailored by manufacturing method (bar stock, welded, forged)
• Reynolds Number Range: From ~210 up to 210 depending on size and construction
• Materials: Carbon steel, SS304/316/L, duplex/super duplex, Hastelloy, Inconel, Monel, titanium, aluminium, and specialty alloys
• Pressure Rating: ANSI 150API 15K (up to 2320 psi), higher ratings on request
• Construction Types: Machined (bar-stock), welded plate, cast, or forged bodies depending on size and application

Technical Performance

Accuracy:

Uncalibrated accuracy typically 1%3%

Accredited lab-calibrated accuracy as tight as 0.2%0.5%

• Permanent Pressure Loss (PPL): 5%15% of generated differential pressuremuch lower than orifice plates
• Repeatability: 0.1% in most designs
• Rangeability: Typically 3:1 to over 10:1 depending on instrumentation setup
• Straight run Requirements: Short inlet/outlet runs (as per ISO5167) needed; less piping space than orifice meter .

Construction Features

Venturi tubes include:

• Inlet cylinder smooth entry to minimize turbulence
• Convergent cone accelerates fluid to generate drop
• Throat constant-diameter section for DP measurement
• Divergent cone recovers pressure efficiently

They come with pressure tapping options such as annular chambers, piezometric rings, or direct taps; paired with flanged or welded ends

Key Benefits

• Lowest permanent pressure loss among DP flow elementssaves energy and operating costs
• Robust & durable: No sharp edges, resistant to erosion, handle slurry or dirty fluids
• High accuracy and repeatability: 0.2% calibrated, 0.1% repeatability .
• Compact footprint: Short straight run requirementsaves piping space .

Applications

Ideal for high precision flow measurement across industries:

• Oil & Gas / Petrochemicals: custody transfer, pipeline metering, refineries
• Power & Steam: boiler feedwater, steam turbines, geothermal lines .
• Chemical / Water Treatment: aggressive or slurry flows .
• Industrial Processes: compressors, large pipes, gas distribution .
• HVAC & Utilities: large duct or pipeline flow in power plants and central utilities.
