Our stub is made of a novel new welding technology.
Traditional stub was made by the way of a Nickel-plated layer and a Copper hardfacing, and the manufacturing process is rather difficult and is likely to have defects in the final products, and hence the life time is always not satisfying.
Against the traditional way, our engineers analyzed the traditional process and found the most suitable way, diffusion welding, for this product.
With this innovative diffusion welding technology, the joint is built directly between stainless steel and copper, and this joint is much stronger than the dtraditional way, thus the life time is improved dramatically.
