Weldolet · forged A105 · MSS SP-97 · UAE stock

The most widely used olet: a forged, contoured outlet that welds onto a header and provides a bevelled butt weld branch at 90 degrees. Its integral reinforcement replaces a reducing tee and removes the need for a reinforcing pad.

Overview

Forged weldolets to MSS SP-97 for reinforced header branches

A weldolet is a forged branch outlet with a base contoured to the header OD and a bevelled outlet matching the branch pipe. It is welded to the header over a cut hole and the branch pipe is butt welded to its top. MSS SP-97 requires the fitting itself to replace the metal removed from the header, so a correctly specified weldolet needs no extra pad. Weldolets are lighter, cheaper and quicker to install than a reducing tee once the header exceeds about 2 inch.

Hamza Fasteners supplies A105 weldolets in STD, XS and Schedule 160 bores, contoured for a wide range of header sizes, and in A350 LF2 or stainless on request. Applications include process and utility headers, pipe racks, pipeline tie-ins, fire mains and offshore piping. Order as header x branch x schedule, for example 10 x 2 inch XS, and our Dubai team will quote quickly.

FAQ

Common questions

When should I use a weldolet instead of a reducing tee?
As a rule of thumb, use a weldolet when the header is larger than 2 inch and the branch is smaller than the header. It removes two butt welds from the run, saves weight and cost, and still provides full reinforcement under MSS SP-97.
Does a weldolet need a reinforcing pad?
No, not when selected correctly. A weldolet is designed so that its own body replaces the metal removed from the header. Your piping engineer should still confirm suitability under the applicable code, such as ASME B31.3.
Do you only carry weldolets in one schedule?
No. Weldolets are supplied in STD, XS and Schedule 160 bores, contoured to a wide range of header sizes, with sockolets and threadolets available for smaller branches. If a size is not on the shelf, we give a firm lead time before you commit.
How much do weldolets cost in Dubai?
Price for weldolets depends on size, pressure class, end type and order quantity. Send your list on WhatsApp with size, class, end type and quantity and our team will reply with a same-day price from Deira, Dubai.
Do you deliver weldolets across the UAE, GCC and Africa?
We deliver across the UAE from Dubai, usually within one to two working days for stock sizes, and export to GCC countries and East and West Africa. Test certificates travel with the shipment when requested.
How is a weldolet welded to the header?
Cut a hole in the header matching the weldolet bore, set the outlet in place, and make a full penetration groove weld around the base, finishing with a fillet cap as required. The branch pipe is then butt welded to the bevelled top.
