【Attention for seat surfacing】:

In the generation and application of butterfly valve are indispensable to the use of welding technology, the butterfly valve seat needs surfacing welding, then when welding we should pay attention to what? The following free from the professional production of big size butterfly valve zfvalves sorting release and hope to help with you:

* VT (visual inspection) is usually used to check for obvious welding defects, such as cracks, edging, molding defects, burn-through, spatter, etc

* When the sealing surface is finished, it is usually checked for cracks by PT according to the customer's requirements,

* The hardness of sealing surface should be tested after surfacing.

* Common surfacing materials:1CR13、2CR13、Stellite6、Stellite21、Stllite12、Cobalt-base alloy、Monel...
