6D Seamless Pipe Bend

6D Seamless Pipe Bend

Pipe bends can be welded or seamless depending on their make. Pipe bends can be cost-effective compared to elbows. The bends have a curvature defined by the bend radius. The bend radius of a 6D Seamless Pipe Bend is six times the outer diameter of the bend. If the bend has a radius six times the outer diameter and the bend is produced seamlessly, then it is known as a 6D Seamless Bend. The higher the radius is the smoother the flow of liquids inside the bends is.

What does 6D mean for buttweld fittings?

  • Bend radius is 6 times the pipe O.D.
  • Example = if a 6D pipe bend used in a 10″ (inch) diameter pipe
  • Centerline radius of the bend would be 60″ (inch)

90 Degree 6D Pipe Bends and other bends can be tested with a number of destructive and non-destructive methods. The mandatory test is the ultrasonic test. It involves scanning the bend under ultrasonic sound waves. This allows the tester to see the even distribution of the thickness and material throughout the bend. The Buttweld Stainless Steel 6D Bend can be tested through magnetic tests, hydrostatic tests, x-ray tests, and other optional tests. The hardness of the bend has to be tested along with the tensile test. To confirm the composition of a bend, a chemical test is carried out.

The price of the elbows is usually higher than the bends. Depending on the specification of the bends and the availability, the prices can differ. The Induction 6D Bends are made through an induction process that involves a lot of electric power. The cost and consumption of electric power, the country of manufacture, and the transportation of raw materials all play an influencing role in deciding the 90° bend or the 6D 45 Deg Bend or any other bend cost. Your location, your purchase location, the logistics, and the availability can decide the purchase of the bends.

Most pipes of this type can be made through the induction bending or heat bending procedure. The induction bending of the 6D Short Radius Bends involves heating a piece of pipe through an induction coil. The correct length of a piece of pipe will be placed inside the hydrostatic placer, and the levers in the machine will place the ends of the pipes at the required length. When the induction coil is powered up, it provides the necessary heat, often in the order of 700-800 degrees Celsius. At this heat, as the arm pushes the pipe, it bends to the desired angle and curvature. After the angle has been achieved, the bend is placed under water or cold air to cool down gradually.

Any piping component is coated to provide extra protection to the piping. The fittings can be coated with different elements and compounds. The Long Radius 6D Bend can be coated with 3LPE external coating, FBE coating and Epoxy resin paint can be applied internally or externally. Cladding and lining can be done. For water pipe bends, an anti-rust painting can also be applied. All these coatings provide an extra layer of corrosion resistance, temperature resistance, and abrasion resistance depending on the material used for coating. Galvanizing can also be applied to certain types of bends.

The bend has a certain weight and it is important to calculate the weight of the SMLS Hot 6D Bending because it affects the total weight of the piping. To measure the weight, the total volume of the material used to make the bend is needed. This can be calculated by measuring the thickness of the bend, and the total surface of the bend and multiplying the two. The 6D Bend Radius can be used to calculate the surface area of the entire bend. Once the total volume of the material is known, it can be multiplied by the density of the material to gain the weight.
