2202 Series complete hammer union set, 15,000 psi cold working pressure, butt-weld × butt-weld at Schedule XXH. Sour-service (NACE MR0175) only — the H₂S-rated equivalent of the 1502.
The Hammer Union Set, 2202 Series Butt-Weld Schedule XXH, 15,000 psi, Sour Service (NACE MR0175) is a complete wing-union (hammer-union) set comprising a Male sub, a Female sub, and a hand-tightened wing nut for hammer-tightened assembly. The 2202 series is the sour-service equivalent of the 1502 — same 15K cold working pressure, but butt-weld-only at Schedule XXH wall thickness, AISI 4130 forged, and NACE MR0175 hardness-controlled throughout. It carries no threaded variant. Charpy V-notch impact testing at low-temperature is included with every unit. Rated for 15,000 psi working pressure in sour (nace mr0175) service. NACE MR0175 / ISO 15156 sour-service compliant — H₂S-rated body and trim with hardness controlled per the standard.
Stock or short-lead nominal sizes: 2 in, 3 in, 4 in. Other sizes within the same series can be sourced build-to-order at typical 8–14 week mill lead times. Indus quotes a firm size, pressure class, end-connection style, 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.
Cold working pressure 15,000 psi (15K class), sour (nace mr0175) rated. Bodies are forged from AISI 4130 alloy steel and tempered to the working-pressure design. Hydrostatic test at 1.5× shell pressure on every unit. Mill test reports per EN 10204 3.1 / 3.2 supplied with each shipment. Charpy V-notch impact testing available where service requires low-temperature toughness verification.
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):
Confirm on your RFQ: (a) exact nominal size and bore ID, (b) line working pressure and pressure class, (c) end-connection style on each port (NPT thread, butt-weld, integral / non-pressure thread sealing end), (d) service class — sour (NACE MR0175) or standard, (e) any auxiliary requirement (charpy testing report, low-temperature certification), and (f) destination port for door-to-door logistics. Indus quotes ex-Dubai with full traceability.
Pair with matched-pressure crossover unions, integral crosses / tees / elbows, swivel joints, pup joints, and adapter flanges of the same WECO figure class. For the higher-pressure frac series (1502 / 2202), also specify API 6A flanges, ring-joint gaskets, and BSL stud-and-nut sets in the matched pressure class. Hammer-union gaskets (Buna-N, Viton, HSN, FFKM) are sold separately — confirm fluid chemistry to match elastomer.
