PolyClad horizontal rigs for internal cladding of pipes up to 18 m long
Country: · Model: PolyClad
PolyClad is a horizontal rig for internal anticorrosion cladding of pipes up to 18 m long with an inside diameter from 5″. The pipe rotates while the torches with wire feeders move along the inner wall. Such lines produce clad pipes for oil and gas, subsea and offshore facilities and nuclear power.

Description
The pipe rotates around its longitudinal axis, while the torches on the welding lance, together with the wire feeders, travel along the inner wall. The torches and lances have a camera for continuous process monitoring. The Full Length Cladding Rig clads the pipe over its full length with two TWIN TIGer torches, the standard length is 18 m, and horizontal TWIN-TIGer rigs for 12 m are also in operation. The Pipe End Cladding Rig has a single torch and two synchronized PC 600-3 HW power sources, which drive the lance, rotate the pipe and feed the TIGer torch. TIGer lances, standard and custom, clad pipes with an inside diameter from 100 mm, and for smaller bores TIG HW lances are fitted.
How to choose
First decide what is to be clad. The full pipe length is taken on the Full Length Cladding Rig, while short and medium pipes or only the ends fit into the Pipe End Cladding Rig with one torch. Then look at the bore, because from 100 mm TIGer lances work, while in smaller pipes TIG HW remains, with three times lower deposition rate.

FAQ
What is the TIGer process and what is its deposition rate?
It is a twin-electrode hot-wire TIG process developed in 2013. According to the manufacturer, the deposition rate is 2.5–6 kg/h, three times higher than with TIG HW.
What are the layer thickness and the dilution with the base metal?
The layer thickness is 1.5–3.5 mm. Dilution is about 12% in the first layer and 1.5–2% from the second.
What is the cladding speed with TIGer wire?
With 1.2 mm wire it reaches 2000 mm/min in some applications. The cost per kilogram of deposited metal falls by 20–50%.
What iron content is obtained when cladding with Inconel 625?
A user of the rig reports an iron content below 3% at a distance of 3 mm from the base metal.
What is the smallest pipe that can be clad on PolyClad?
An inside diameter from 5″. TIGer lances work from 100 mm, and for smaller bores TIG HW lances are fitted.
