Description

Welding Neck Flanges are easy to recognize at the long tapered hub, that goes gradually over to the wall thickness from a pipe or fitting.

The long tapered hub provides an important reinforcement for use in several applications involving high pressure, sub-zero and / or elevated temperatures. The smooth transition from flange thickness to pipe or fitting wall thickness effected by the taper is extremely beneficial, under conditions of repeated bending, caused by line expansion or other variable forces.

These flanges are bored to match the inside diameter of the mating pipe or fitting so there will be no restriction of product flow. This prevents turbulence at the joint and reduces erosion. They also provide excellent stress distribution through the tapered hub and are easily radiographed for flaw detection.

This flange type will be welded to a pipe or fitting with a single full penetration, V weld (Buttweld).

As our develop strategy, we have been focusing on the complete production process mode which we deem will bring us synergy, so recently, another new product, i.e. welding consumables will be added to our catalog which will cover all series such as gas-shielded solid welding wire、flux cored wire、submerged arc wire、argon arc wire etc.

We have two main advantages for LT welding wires:
Fully integrated production process, i.e., with the support of upstream world class steel making facilities in house from same group company.
Newly developed production process with latest technology and know-how, i.e., fully automatic production which will be the assurance of quality control.
