Available sizes

This product family covers the following stock or short-lead nominal sizes: 2 in, 3 in, 4 in (and bore-equivalent API sizes). Other sizes within the same series and pressure class can be sourced from the OEM mill on a build-to-order basis (8–14 weeks lead). Indus quotes a firm size, pressure class, configuration, and service-class match against your inquiry data sheet — call or RFQ with the line specification and we will return a complete matched bill of materials.

Performance

Working pressure 15,000 psi (15K class), standard rated. Manufactured to recognised oilfield frac-iron design standards — pressure-class methodology and hydrostatic testing aligned with API 6A. Hydrostatic test at 1.5× shell pressure on every unit. Mill test reports per EN 10204 3.1 / 3.2 supplied with each shipment.

Applications

• Compact wellhead skid pipework
• Process-plant high-pressure tie-ins
• Subsea / tight-tolerance assemblies

OEM equivalents and compatibility

This product is supplied as a recognised matched-pressure interchange for the following OEM standards and product lines (no implied authorised-distributor relationship — supplied by Indus Hydraulics):

• Grayloc / Oceaneering
• Vector / Cameron
• NOV Hub-Clamp

Compliance

• Recognised oilfield frac-iron design standards (frac-iron pressure-class lineage)
• EN 10204 3.1 / 3.2 mill test reports
• Hydrostatic test certificates per unit

How to order

Confirm on your RFQ: (a) exact nominal size and bore ID, (b) line working pressure and pressure class, (c) end-connection style and gender on each port (M / F, NPT / BW / Integral / RTJ / RF), (d) service class — sour (NACE MR0175) or standard, (e) any additional ports or taps (1/2 in NPT instrument tap, 9/16 in Autoclave, etc.), and (f) required certifications beyond the standard MTR + hydrostatic. Indus quotes ex-Dubai with full traceability.

Companion products

Pair with matched-pressure hammer unions, swivel joints (Chiksan-style 50 / 100 / 200 series), pup joints, integral crosses / tees / elbows, plug valves, ball valves, and check valves of the same WECO figure class. For wellhead and frac-tree integration, also specify API 6A flanges, wellhead adapters, and ring-joint gaskets in the matched pressure class.
