90 Degree Elbow

ASTM A234 WPB 90° Long Radius (LR) Seamless Elbow is a carbon steel butt-welding fitting manufactured to ANSI B16.9,

designed to change flow direction by 90° in industrial piping systems. The long radius design

(center-to-end radius = 1.5 × NPS)

provides lower flow resistance and longer service life compared to short radius types.

Size of product:

Key Features:Seamless construction — uniform wall thickness, no weld seam, reliable under pressure.

A234 WPB grade — good impact toughness and weldability, suitable for low & medium temperature service.

Long radius geometry — minimizes turbulence, pressure drop and erosion.

Beveled ends — ready for direct butt welding on site.

Black anti-corrosion coating — standard protection for storage and sea freight.

Typical Applications:

Petroleum refineries & petrochemical plants

Natural gas & oil pipelines

Power generation (boiler & cooling water lines)

Chemical processing

Shipbuilding & offshore

General industrial piping, HVAC and fire protection

Surface & Packaging:

Surface: Black varnish / bare black / hot-dip galvanized (on request)

Ends: Plastic caps or steel protection rings

Packing: Plywood cases / pallets, seaworthy export packing
