Pipe Cross

A pipe cross is a kind of pipe fitting that be used in the place where four pipes meet together.

The pipe cross may have one inlet and three outlets, or there inlets and one outlet. The diameter of the outlet and inlet can be the same and can also be different. That is to say, straight cross and reducing cross are both availabe.

A cross fitting allows four direction transition in pipeline fields.

Features of Pipe cross:
  • There are three female openings in a T shaped pipe cross.
  • There are straight pipe crosss which have the same size openings.
  • Reducing pipe crosss have one opening of different size and two openings of the same size.
  • There are sanitary pipe crosss which are used in waste lines. These kind of pipe crosss have a curved branch which is designed for a clean out plug. They are used to prevent obstruction of waste.
  • A cross pipe cross has four equal sized female openings.
  • A wing pipe cross has lugs to fasten the fitting to a wall or stud.
  • A compression pipe cross uses compression fittings on two or more ends.
  • A test pipe cross has a threaded opening. This opening is used in conjunction with a threaded plug for a clean-out opening on a drain pipe.

Buying Tips of pipe cross

What should buyers consider for bulk purchase of pipe cross?

  • Type of pipe cross—whether welded or seamless
  • Standard
  • Size and dimension
  • Wall thickness
  • Material of construction
  • Durability and Economical
  • High pressure and temperature resistance
  • Corrosion resistance etc.

Pipe cross, LT, Lateral cross , RT, Reducing cross, cross fittings accord to ANSI, ISO, JIS and DIN Standards, Measures 1/2 to 56 Inches.

Threaded Cross
  • Size range: 1/2 to 20 inches
  • Types: Straight cross, Reducing cross, Y-type
  • Pressure: SCH5 to SCH160
  • Standard: ANSI B16.9/B16.28, MSS SP-43/SP-75

The fitting not only played a role in conection the cossing pipeline but also can control the volume by designed with different dimension of cross ends,sometimes we also adopt rib to reinforce the mechanical property when face hard woeking conditions.
