What are pipe crosses

What are pipe crosses?

Pipe crosses, also known as four-way fittings, have one inlet and three outlets and typically have solvent weld sockets or female threaded ends. The ends are positioned at a 90 degree angle and the threads are designed to create a stable grip and ensure a connection to the male threaded fittings. The pipe cross can be divided into equal diameter and reducing diameter, and the connecting pipes of equal diameter cross are of the same size; The size of the main pipe connecting pipe of the reducing cross is the same, while the size of the branch pipe connecting pipe is smaller than that of the connecting pipe.

Types of pipe cross

A pipe cross allows four direction transition in pipeline system. Let us know more about pipe crosses under the following heads:

Features of pipe crosses

  • There are three female openings in a T shaped pipe cross.
  • There are straight pipe crosses which have the same size openings.
  • Reducing pipe crosses have one opening of different size and two openings of the same size.
  • There are sanitary pipe crosses which are used in waste lines. These kind of pipe crosses 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.

Size of pipe crosses

Manufacturing process of pipe cross

The process flow of pipe cross is as follows:

  • Incoming inspection of raw materials → blanking → pressing → heat treatment → pickling → reshaping → polishing → rolling sand → groove → pickling passivation → identification → inspection and warehousing

Incoming inspection of raw materials

The steel pipes must comply with the provisions of corresponding steel pipe manufacturing standards. The quality certificate of the manufacturing company shall be provided. When the steel pipe enters the factory, the quality inspector and keeper shall inspect and accept the diameter, wall thickness and appearance quality of the steel pipe.
Whether the mark and furnace batch number of the pipe material are consistent with the material certificate. Recheck the chemical composition analysis, mechanical property analysis and metallographic structure analysis according to the standards and the requirements of the demander.
The inner and outer surfaces of seamless steel pipes shall be free of cracks, folds, folds, delaminations, cracks, scabs and other defects.
The steel pipes shall be neatly arranged in the stockyard or workshop, and shall not be placed disorderly, there shall be no extrusion or collision of heavy objects, and there shall be no collision during hoisting..

Blanking of pipe cross

Sawing machine or automatic flame cutter shall be used for blanking.
The blanking length shall meet the technical requirements.
The two end faces of the cut pipe section shall be leveled by turning method.
Ensure the perpendicularity deviation of the two ends facing the axis and the parallelism deviation of the two end faces.

Pressing of pipe cross

During pressing, the corresponding pressing mould shall be selected according to the specification and model. The power equipment is a four-way hydraulic forming machine. Before pressing, the equipment shall be checked to confirm that it is in good operation.
Correctly adjust each limit switch and check the effectiveness and sensitivity of each control switch.
The equipment shall be operated by a specially assigned person. During the production process, pay attention to the reading of pressure at all times and make corresponding adjustment. In case of emergency such as abnormal pressure or unable to push, stop the machine immediately for inspection.
After the press is started, it is not allowed to put the head, hand and other body parts into the working table of the press.

Heat treatment of pipe cross

After the cross is extruded, heat treatment shall be carried out to eliminate the stress generated in the cold extrusion process.
Heat the seamless steel pipe to 727 ℃ to 912 ℃ or 30 ~ 50 ℃ above the critical temperature of Austenite for a certain time (the constant temperature time is 1H per 25mm wall thickness and shall not be less than 15min), and then conduct rapid water cooling.

Pickling of pipe cross

Remove the residue left on the surface after the solid solution of the cross.

Reshaping of pipe cross

Keep the diameter of the cross within the standard.

Polishing of pipe cross

The materials required for polishing include polishing wax, hemp wheel, nylon wheel, cloth wheel, wind wheel, thread cloth wheel, etc. Surface polishing can make the pipe fittings into mirror effect and improve the corrosion resistance of the pipe fittings. Internal polishing is mainly to prevent the fluid substances in the pipe from forming hanging wall in the pipe. It is easy to cause pollution and blockage in the pipe after a long time.

Rolling sand of pipe cross

Sand rolling is a surface treatment method, that is, the processed products are put into the sand rolling cylinder, and the elbow and sand roll together, so that the rust and burr fall off and the edges and corners are smooth. The elbow with good sand rolling can increase the wear resistance and hardness. The cost is higher than sandblasting, but the surface gloss is much better.

Groove of pipe cross

Groove equipment adopts ordinary lathe.
The burr generated by the groove shall be polished clean.
The groove angle is 37.5 ± 2.5 °.

Pickling passivation of pipe cross

Black and yellow oxide scale will appear during the processing of stainless steel pipe fittings. In order to improve the beauty and corrosion resistance of stainless steel, the processed pipe fittings need to be pickled and passivated. The purpose is to clean the oxide scale generated after processing, so that the pipe fittings are silver white, and an oxide film with chromium as the main material will be formed on the surface, so as not to cause secondary oxygen corrosion of the pipe fittings, so as to achieve the purpose of passivation, so as to prolong the service life of the equipment.

Identification of pipe cross

The finished cross shall be provided with durability identification with clear writing.
If the demander has specified the identification method, it shall be implemented according to the demander’s regulations; If not specified by the demander, the standard shall be implemented according to the product performance.

Inspection and warehousing of pipe cross

The geometric dimension and appearance of the cross shall be inspected by the quality inspector before warehousing.
The internal and external surfaces of the Cross shall be free of scratches, grooves or obvious depressions formed by collision, and there shall be no defects such as cracks, scarring, folding, delamination and so on.
Geometry inspection shall be carried out according to the standard.
The cross inspection record form shall be filled in for inspection.
The cross can only be put into storage after passing the inspection. It shall be neatly placed in the designated inventory area according to the specification and model, and ensure that it is free from dirt and collision.

How to buy pipe crosses

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

Applications of pipe cross

Pipe crosses are widely used in various commercial and industrial applications. Industrial applications include:

  • Chemical processing
  • Petroleum
  • Pulp/paper
  • Refining
  • Textile
  • Waste treatment, Marine
  • Utilities/power generation
  • Industrial equipment
