hy do you need to choose Keyhole tig to weld pipe and vessel

Keyhole tig can weld X70 pipes with a diameter of 1000mm and a thickness of 8mm within 10 minutes

What is the maximum diameter of pipe and vessel diameter that can be welded by Keyhole TIG?

There is no maximum pipe or vessel diameter which can be welded by K-TIG.

What is the minimum diameter of pipe and vessel that can be welded with Keyhole TIG?

Keyhole TIG can readily weld pipe diameters down to 75mm.
The reason for this is that managing the tie-in on pipes with diameters smaller than this becomes challenging as the weld is completed within seconds , requiring that the tie-in of the beginning and end of the weld is over very hot material.for example 4mm stainless steel welding speed is 500mm/min ,the keyhole tig system will complete the welding of  75mm diameter pipe within 30 seconds
What can Keyhole tig do for you?
Keyhole TIG technology reduces the preparation time needed for welding in the pipe manufacturing industry, greatly improving productivity. With square edged butt joins achievable in up to 16mm thick materials, edge preparations are a thing of the past.
Keyhole TIG welding takes less than one tenth of the time of traditional TIG welding, and consumes a fraction of the material and power. The cost savings that flow from this are massive.
The technology of Keyhole TIG also improves the quality of the pipes being manufactured, with improved weld consistency. As pipe-makers know, one defect in a weld join can set back production by days, adding huge costs and delays to projects. The technology of Keyhole TIG reduces the chance and number of defects. How does it do this?
Unlike traditional TIG welding, the penetration of Keyhole TIG means it is possible to weld up to 16mm thick material with a single pass from the outside of the pipe only. Keyhole TIG requires no filler materials for welds up to 16mm thick, resulting in a much cleaner weld by reducing the amount of foreign material, therefore reducing the risk of corrosion. Reduced risk of corrosion means improved safety of pipes.
