Production Information

The full name of water-cooled wall is "water-cooled wall tube", formerly known as "water-cooled wall", also known as "riser". It is usually laid vertically on the inner wall of the furnace wall, which is mainly used to absorb the radiant heat emitted by the flame and high-temperature flue gas in the furnace. It is the main type of evaporation heating surface of various modern boilers, and it is also the basic component of boiler water circulation circuit. Because it has the functions of cooling and protecting the furnace wall, it is called water-cooled wall

After the pipes processed by surfacing process are manufactured into the water wall, the corrosion resistance and service life of the water wall can be improved, thus reducing the production cost of the company

Nickel base weld overlays are commonly used in the Power Industry to extend the life of equipment subjected to aggressive corrosion enviroments.

As boiler conditions have become more aggressive over the years,Nickel base alloy overlays have become more commonly used,not just for repair and maintenance purposes,but also as a cost effective solution for new boiler installations.

The most common problem in surfacing is cracking. The main methods to prevent cracking are as follows

1. Preheat before welding, control interlayer temperature and slow cooling after welding

2. Stress relief heat treatment after welding

3. Avoid multi-layer surfacing and use low hydrogen surfacing electrode

4. If necessary, build up the transition layer between the surfacing layer and the base metal (use the electrode with low carbon equivalent and high toughness)

Attention must be paid to butt welding:

1. According to the use requirements, reasonable selection of surfacing alloy

2. Reduce the dilution ratio of base metal as much as possible

3. Improve productivity

4. It is expected that the hardfacing metal and base metal have similar expansion coefficient and phase transformation temperature

Purpose of Inconel Cladding on surface :

1. Extend service life

2. Reduce costs

3. Reduce spare parts

4. Reduce maintenance
