- A speed drill rod is essentially a tubular component that connects the drill bit to the drilling rig. It serves as the conduit through which drilling fluid is circulated, ensuring efficient cooling and removal of cuttings. However, what sets speed drill rods apart is their ability to withstand high torque and rotation speeds, translating into faster drilling rates.
Due to the hard carbon nanofibers and abundant welded joints among the nanofibers, the hard carbon aerogels display robust and stable mechanical performances, including super-elasticity, high strength, extremely fast recovery speed (860 mm s-1) and low energy loss coefficient (<0.16). After tested under 50 % strain for 104 cycles, the carbon aerogel shows only 2 % plastic deformation, and retained 93 % original stress.

As the name suggests, molded grating is created on the mold; whereas pultruded grating is created by combining the pultruded profiles in the shape of grating. Molded fiberglass grating is a combination of thermosetting resin with fiberglass roving to create a strong one piece panel.



When installed in manholes or potential pedestrian traffic areas, flow monitoring flumes can be a hazard. A typical flume installation is an open trough that that an operator can inadvertently step or fall into.
