Avoid direct contact with the live parts of welding equipment and the workpiece. An underground storage tank (UST) system is a tank (or a combination of tanks) and connected underground piping having at least 10 percent of their combined volume underground. The heated or vaporized fluid exits the boiler for use in various processes or heating applications, including water heating, central heating, boiler Welding is generally suited to joining large assemblies where both metal sections are relatively thick (0.5/12.7mm) and joined at a single point. The pressure of acetylene drawn from the generator is quite low, i.e., less than 0.07 bar. Sparks can travel up to Inspect hoses for leaks and worn places. prior to use. NFPA 30 states that piping shall comply with ASME B31 and that low melting point allows (such as bronze, aluminum, nickel, etc) may be used underground or where they do pose "undue risk". API (American Petroleum Institue) 653 is the standard used to govern repairs and alterations of petroleum tanks of all varietes. Introduction to Flanges. Example: a hydraulic system has a flow rate and tube diameter to achieve Re=3,400 in normal service. Electric shock. 3) More cable types are allowed for Div. As well as flammable liquids such as petrol, diesel and fuel oil, substances such as paints, glue, anti-freeze and cleaning agents may also release flammable vapours. OSHA Fact Sheet (Publication 3647), (2013). Welding, cutting, and allied processes produce molten metal, sparks, slag, and hot work surfaces can cause fire or explosion if precautionary measures are not followed.

Reason #2: They are not given a copy at their station. Toolbox Talks was originally used as a way to encourage building workers to have regular documented safety meetings. Always insulate yourself from the work and ground. a. any reducing regulator b. an approved gas specific pressure reducing regulator c. a inch copper coil d. a manifold unit 4. 2 fuel oil shall be provided with a device to indicate at the fill point, either visually or audibly, when the oil in the tank has reached a Underwater welders are specially trained, and they must be a good swimmer in order to prevent this to happen. Do not expose bare skin to flux fumes. Acetylene welding was first used around 1911 to join pipe segments together (girth welding) and just prior to 1920, arc welding was introduced. 348]] Public Law 115-141 115th Congress An Act To amend the State Department Basic Authorities Act of 1956 to include severe forms of trafficking in persons within the definition of transnational organized crime for pipes. It is critical to ensure high quality welds to ensure safe plant operation. If the tank is large enough to allow entry, cleaning and ventilation along with Gas free services would be you most economical solution. The tank system includes the tank, underground connected piping, underground ancillary equipment, and any containment system. This pertains to light fuel oil (#1 or #2 diesel). weld joint, 2.) When not in use, manifold and header hose connections must be capped. Welding: On the other hand, welding will require a hot works permit and a lot of planning beforehand, which means that you will be waiting much longer for a welded system. They install steel fittings dry, or with red Loctite. 2. Never use copper couplings with acetylene. Apply Flux to Your Brass Pieces. Assess weld joints to ensure there are no excessive gaps, as poor part fit-up can lead to issues like burn-through or distortion. Clamp or fixture the part in the correct position. In addition, it must say that standard ASME B16.9 used for butt welding reducers and B16.11 for forged steel, socket welding and threaded ones. It can also damage the insulator in the nozzle. Do not use a regulator for more than one type of gas. Defective tack welds must be removed prior to the actual welding of the joints. The problem is that during normal use, drill pipe acquires the properties of a permanent magnet. Again, ensure that the wire type and diameters and the gas and the gas mixture are compatible. Chills Rings are sometimes called backup rings or spacers. It is mainly used in ductwork and piping applications and is also known as thread seal tape and plumber's tape. Hydrostatic testing of pressure piping is a mandatory activity before finalization of any new or modified piping system. Which lubricant(s) should be used when connecting the parts of an oxy fuel gas welder? One of the biggest problems is the controversial pipeline welding technique used in the 1970s. electrode coating, and 6.) It is the final check of mechanical integrity of the whole system and should be followed religiously as after this activity the piping system has to be commissioned. The fuel fittings are removed from the end of the hose differently. A pH range of 8 to 10.5 is commonly used for pipe systems that include steel. As important as it is to have written WPSs most fabricators dont have them. If the wall thickness in the weld area is too thin, the operator must extend the sleeve area on the pipe. Fittings: Fittings allow for quick and simple repairs to be carried out to the structure. Welding, a process that dates back to the Iron and Bronze ages, has evolved into a highly specialized procedure that provides innumerable benefits across a range of industries and applications. Inspect hoses for defects/deterioration before use. The fluid velocity (V) should not be less than 2 to 3 m/sec. Before using a welding arc, gear up in welding helmet with fitted lens, welding gloves, welding jacket, leather apron and thick leather boots. 7.6 (a). welding tip. Pipe welding is a method for joining two pipes together. Always double check. Never use oil on the threads or fittings! The median wage for this role is around USD 58,000 annually. This fitting then becomes part of a system for transporting fluids (oil, gas, steam, chemicals, ) in a safe and efficient manner, over short or long distances. in any part of the flushing loop.

It allows for real good control of the flame and is soft enough to prevent blow through on aluminum. I learned that gas welding of oil soaked aluminum is the only way to ensure a leak free weld. General Gas Welding Safety Tips. Could you get a piece of angle iron and drill a few holes through the angle iron and angle bracket and then weld a coupling to the angle iron and bolt the setup to the tank bracket. Avoid standing in water, on wet surfaces, or working with wet hands or wearing sweaty garments. Do not dip energized (hot) electrode holders in water. Avoid direct contact with the live parts of welding equipment and the workpiece. The preparation for gluing each type of pipe is slightly different. Pacific Oil Cooler Service notes their number-one issue with installations is thread-galling aluminum AN fittings (left). At the low end of the median pay scale, the average salary is USD 53,000, and at the top, it is USD 89,000 annually. You need a tin based flux, also known as a brass soldering flux. The pH scale is logarithmic and commonly ranges from 0 to 14. The fluid does not necessarily boil. Adapters must not be used to permit the interchange of hoses. ASME B16.34 is also mentioned in the more general ASME spec ASME B31.1, Power Piping Design.. Back in 1988, the scope of this standard was modified to include threaded-end and weld-end valves in addition to flanged-end Process, Pipe & Fitting Mat, Dia. 1 areas must be listed for Class I, Div. The process is being used to join or create small and large components, and its success has largely been attributed to vacuum solutions. Keep oxygen cylinders and fittings away from oil and grease. Protect hoses and cylinders from sparks, flames and hot metal. welding technique, 4.) Do not use oxy-fuel equipment near oil or grease contain-ers.
