Q:I hope you can help me with my question regarding the Cement-lined pipe.The contractor in a water treatment plant changed the specified Stanless steel pipe to Cement-lined DI pipe.This will be used in air application from blower, air will have a velocity of 23m/s.Is this an ideal application for Cement-Lined Ductile Iron Pipe??
No. The concrete is rough and will disrupt air flow. Those pipes are for wells.
Q:Please help!A couple of months ago i adopted a cat from the cats protection league. she is now starting to go out but she seems to always go up onto my cement bonded asbestos garage roof to go to the front of my house. When i call her back in, she goes on the roof to get back to my back door. Can she get asbestos fibers from the roof which is not broken on her paws.
Undamaged asbestos that is bonded into cement tiles, typically pose as a low risk to public health, but still a risk. Evidence, using electron microscopes, show that asbestos cement products release fibres into the air under normal wear and tear conditions. A 1980 study showed that asbestos was found in the air within 20 inches of a 17-year-old weathered asbestos cement tile. It is 10Xs higher than 100 meters (328 feet or 33 yards) from the same wall. Blue and Brown asbestos are generally considered to be more deadly than White asbestos. Also, outdoor cats lives are shortened by 2/3% then an indoor cat and vet expenses are higher due to diseases, fights, accidents, poisons, stranger mistreatments, traps, etc. situations that the cats may get into. Good luck!

Q:i need some info on CEMENTED CARBIDE, its cost, its manufacture process, availability, its uses and applications.plz help ! thank u !-ABISH
There okorder and search for carbide. Of course, there are other applications for carbide other than as cutting tools. Because it is extremely hard, it is uses as a bearing material, as extrusion nozzles, as sand blasting nozzles, for high temperature ball bearings, and many other things. Because carbide cutting tools withstand higher temperatures, they can operate at higher cutting speeds. This has enabled a relatively new form of machining aluminum, called high speed machining, in which large billets are aluminum are machined directly to the final shape needed, such as for aircraft parts. High speed machining eliminates casting operations (with the liklihood of defects such as voids and inclusions), as well as making complex assemblies by welding or rivetting smaller components. The result is higher quality with lower tooling cost. The development of carbide materials has changed the metalworking industry.
Q:When i buy it from a cement supply house they charge me sales tax but when i buy it from home depot or lowes they dont. My accountant told me to be careful since i am responsible for paying my taxes.
Do you have a sales tax exemption certificate on file at HD and Lowes, but not at your supply house? If you are not reselling the cement and charging sales tax you are responsible to pay the sales tax to the state. If you charge sales tax the amount you remit can be reduced by the amount of tax you pay to your supply house.

Q:Ferro-cement was the quot;inquot; material to make a boat hull from, and my father was quite taken with the idea behind it. Time and my father have passed, and I am wondering if it is still a viable building material. thank you for your responses.
If made by a professional, the concrete hull has lots of advantages over its FRP cousin. The concrete gets harder as time goes on. The first one made in the 1860's is still afloat. Cement does not blister or delaminate. The weight can be a read advantage when sailing in choppy seas as it will plow through waves that will stop a lighter vessel. If one should encounter a situation that would hole a FRP vessel, the ferro will cave in like an eggshell. Kick it back in shape, slap some fresh cement on it and off you go. Down side is dealing with marinas. They think that you will come flying into your slip and destroy the dock. As long as you are aware of your extra weight and adjust your maneuvers there should be no problems.
