2. The end of Alloy 20 steel pipe and length

PIPE LENGTH

The terms used to designate the length of steel pipes are:

  • “SRL” (“single random length”): means that the pipe has any random size between 5-7 meters; generally, pipes below 2 inches in diameter are manufactured with SRL, i.e. shorter (or half measures) of larger bore pipes
  • “DRL” (double random length): meaning that the pipe has any random size between 11-13 meters. Pipes above 2 inches in diameter are available in DRL size
  • Cut Lengths: pipes are cut according to project specification. Custom sizes are used to save welding costs at the installation site.

The term “random” refers to the fact that the pipe mill can control that the pipe length is between a min-max value, but cannot control the exact length of every single pipe (which will be variable, within the given range).

A double random length pipe has an expected length twice the length of an SRL pipe.

PIPE END TYPES

The term “pipe end” refers to how the pipe is finished at its extremities.

The common pipe end types are:

  • Plain ends (PE): plain ends are generally used for smaller diameters and require slip-on flanges and socket weld fittings. Plain ends are also common for stainless, duplex and nickel-alloy pipes
  • Beveled ends (BE): this is the most common pipe end type (beveled end pipes are joined by welding).
  • Threaded ends (TE): threaded ends (which are generally NPT as per ASME B1.20.1 for petrochemical pipes) require threaded fittings and flanges and are used for smaller size pipelines or gas lines
  • Threaded and coupled ends (T&C), generally used for gas distribution
  • Grooved ends (example Victaulic pipes): these are pipes that allow a quick connection, used for non-critical applications
