Overview

Forged elbows are made from solid bar by hot forging, so the grain runs continuously around the bend. In small-bore high-pressure work — instrument root valves, seal flushes, sample points — that is the difference between a fitting that holds and one that cracks at the thread root.

Range

90° and 45° in socket weld (SW) and threaded (NPT / BSP) patterns; 3000LB, 6000LB and 9000LB.

Standard sizes DN6–DN100, extended to DN150/DN200 on request for heavy-wall pipe.

Fabrication details

Socket depth, bore and wall thickness follow ASME B16.11, so the fitting accepts the matching Sch80/XS or XXS pipe without a mismatch at the weld.

Threads are NPT to ASME B1.20.1 unless BSPP / BSPT is specified.

Sour and cryogenic service

NACE MR0175 / ISO 15156 material with hardness verification is available for wet H2S.

Impact-tested grades are supplied for low-temperature service down to −46 °C and below.

Materials

  • Austenitic stainless (304/316L, 321, 310S)
  • Duplex (2205, 2507)
  • Nickel alloys (C-276, 625, 400, B-2/B-3)
  • Carbon and low-alloy steel (A105, A350 LF2, F5, F11, F22)

Applications

Every shipment can be supplied with an EN 10204 3.1 mill certificate, dimensional report and PMI report. Third-party inspection at SGS, BV or TUV can be arranged on request.
