I also was happy to see a new electronic balometer from Alnor. These devices, which read ceiling-mounted hydraulic diffuser outputs in direct CFMs charge with no correction pump and hydraulic factors, are needed throughout the industry. However, they were usually charge very large, sensitive pump and expensive, so only the largest commercial shops had them, until now. Alnor just introduced its LoFlo balometer, a compact 10-500 hydraulic CFM instrument designed charge specially for residential and light commercial applications.I took a minute to stop by some of the smoky denizens of the welding business. Uniweld Products has pump just come up with a new oxy/acetylene torch tip they call the Tuning Fork (because that''s what it looks like). It hydraulic and charge is specifically designed for the pump removal and installation of reversing valves. Flames coming from both tip surfaces surround the three-connection side of the reversing valve, allowing the whole assembly to be unbrazed in a single operation. Hardfacing hydraulic alloys contain as charge base elements typically iron, nickel, or cobalt, pump to which metallurgists add varying amounts of carbon, chromium, molybdenum, tungsten, silicon, manganese, hydraulic vanadium, and boron. To raise hardness, the primary charge property for wear resistance, alloy designers add elements that either form hard constituents (carbides, borides, or Laves phase), or that strengthen the matrix by going into solid solution. Carbon content determines pump toughness and abrasion hydraulic resistance--as carbon rises, abrasion resistance increases and toughness drops. Chromium forms carbides, charge increases corrosion resistance, and adds high-temperature strength. pump Tungsten, hydraulic a potent carbide former, also boosts charge and pump high temperature hydraulic strength, as does charge cobalt. Tougheners include nickel and manganese. Boron forms hard wear-resistance borides pump.
