EXTERNAL PIPE THREADS

The External pipe threads are of two types, Taper or Straight. These are made according to the guidelines of the standard of American taper pipe threads. The external pipe threads provide the mechanical joints that are free-fitting.

External pipe thread provide better feed rate for the threading and purposes of turning that exist in the traditional ways of threading.

External pipe threads are equipped with advanced technology and are so updated that the use of these threads are preferred on the other pipe threads.

External Pipe threads provide the engineers with the facility to increase the productivity level by utilizing it. They are optimized in a way that makes them efficient and easier to use.

Many countries seem to adapt this advanced system to improve their ways of production with the updated and latest technology that helps them growing their no. of users’ . The major diameter is bounded with an external thread that is usually equal to diameter of the thread of pipe.

External pipe threads are used in industries of food and chemicals. It is also used in the factories of craft some oil and petroleum businesses.

Advantages of PVC fittings

Pan china fastening company is among the top brands in the industry of pipe accessories such as rolled pipes and galvanized nipples. Pipes are widely used all over the world. Pipes are manufactured in different sizes and dimensions. The need of fittings arises when someone needs to join different pipes. Different materials are used for manufacturing these fittings. Some of them are aluminum, PVC, stainless steel and copper. 

Mostly mechanical fittings are manufactured with a pair known as male and female. Pan china fastening company manufactures BSP pipe fittings, DIN, ASTM, GP and NPT. Usually fittings of aluminum and stainless steel are quite expensive. Hence PVC pipes are preferred more.
PVC stands for poly vinyl chloride. PVC pipes are manufactured by mixing chlorine composition too. Which is actually 57%.PVC fittings are of less weight, hence easy to transport.PVC pipes are non corrosive and rust proof hence they are better than copper and iron fittings.

Pipe Nipples

Carefully examine all hydraulic hose, galvanized pipe nipples and fittings at regular intervals to confirm that the pipes are connected in such a way that there is no chance of getting the pipe leak. It help to join one pipe to another.  Investigate any proof of fluid loss or leaks. Check metal tubes for leaks, loose anchorage, scratches, kinks, or alternative injury. Examine fittings and connections for outflow, looseness, cracks, burrs, or alternative injury. Replace or repair defective components. ensure the hoses don't chafe against each other and are properly secured and clamped.

a. Replacement of Metal tube: Once review shows hydraulic hose to be broken or defective replace the whole line or, if the broken section is localized, a repair section could also be inserted. In substitution craft hose, forever use conduit of constant size and material because the original line. Use the previous conduit as a template once bending the new tube, unless it's too greatly broken, within which case a template may be made of soft iron wire. Soft atomic number 13 conduit (1100, 3003, or 5052) beneath half-inch outside diameter could also be bent by hand. For all alternative conduit use a suitable hand or power tube-bending tool. Bend conduit rigorously to avoid excessive flattening, kinking, or wrinkling. Little quantity of flattening in bends is suitable, however don\'t exceed seventy five % of the initial outside diameter. Excessive flattening can cause fatigue failure of the hydraulic tube. once putting in the replacement conduit line it up properly with the union half in order that it\'s not forced into alignment by alteration of the coupling around the bend.

b. Hose couplings and Tube Connections, rolled threaded nipples and several tube connections are made using flared tube ends with standard association fittings: AN-818 (MS 20818) nut and AN-819 (MS 20819) sleeve. In forming flares, cut the tube ends sq., file sleek, take away all burrs and sharp edges, and completely clean. The conduit is then increasing victimization the right 37-degree aviation flare forming tool for the scale of conduit and kind of fitting. A double flare is employed on soft atomic number 13 conduit 3/8-inch outside diameter and beneath, and one flare on all alternative conduits. In creating the connections, use hydraulic fluid as a material so tighten. Over tightening can harm the tube or fitting, which can cause a failure. Under-tightening might cause discharge that might end in a system failure.

ASTM PIPE FITTINGS

ASTM PIPE FITTINGS:
Standards for piping, tubing and fittings:

American Society for Testing and Materials (ASTM) is an international society which provides rules for standardization of pipe fittings. There are different volumes of these standards; Volume 1.01 of ASTM specifies different pipes quality, flanges details and material of steels to be used for piping, tubing and fittings.

Since steel is used in thermal power plants, where these pipes transfer extremely superheated steam, hot water through them i.e. in boiler tubes, turbine and other places .Similarly in refineries, where Oil is transferred to different areas of refinery. This volume gives the details that in these areas how fittings should be done, what type of piping material is to be used from normal to extremely high temperature, so that any chance of fire is eliminated completely.

 

This volume also includes a list of application areas where these standards are applied. Another big advantage of following these standards is that there is assurance of these standards because they are practically verified.
