I am looking at buying some knife gate valves for a slurry application. One of the two options available has a spindle made of stainless steel 304 and the other has a spindle made of chrome steel (303). What is chrome steel?
Can anyone help me with drawings for the correct design of isloating valve, scour valve, air valve and water meter chambers? I am in south Africa please please state what standard you are using.
I supply steel pipes and fittings to civil contractors in the sewer and water reticulation field. I need to download a simple CAD program to assist me in drawing and designing pipes and pipe fittings. Can anyone recommend a good one?
