HIP'ing of High Presssure Valve Bodies
HIP'ing of High Presssure Valve Bodies
(OP)
Has anyone heard of High Pressure Isostatic Pressing being used a method of manufacturing valve bodies especially in duplex construction?
If so:
- names of reputable valve mnaufactuers capable of it will be appreciated, based on previous experience
- does HIP'ing take a longer manufacturing time compared to castings
- Does it cost more compared to castings, though I suspect it does.
Thanks in advance

I have heard it was used for lining of valve bodies to face wear or corrosion issues, just applying a layer of corrosion-resistant material only where it was really required.
Do not know whether they have experiences with valve bodies, but I would give a shot to this.

Pay close attention to the base material properties. The temperatures used in HIP will normally ruin any heat treatment or desired phase of the base material.

We've worked with Kitz on these, with good results.

We buy components from Sadvik and BodyCote.
Lead time is a question of new/existing design, factory loads and designs. If you have a new part, castings require a pattern which needs to be made and qualified which can add months to a delivery cycle. Hipping uses air conditioning style ducting and no pattern. Lead times for hipping are based upon loads at the various shops. The largers diameter we have seen (autoclave diameter) is about 30".
