Seamless Pipe Manufacturing Process
Seamless pipe is manufactured from steel round bar, the bar is heated and pierced to form a hollow billet, after removing oxide scale, billet is extruded into desired dimention using cold drawing and cold rolling methods, this technology can reduce outside diameter to smaller sizes, and control seamless pipe sizes and tolerances requirement, the inside of the tube can be controlled using a rod (known as rod drawing), a plug (known as plug drawing).
Billet
Billet is an extruded hollow tube from pilgered bar, it is actually semi finished tube, and it is needed inspection and pickling to ensure high quality.
Cold Rolling
Billet sizes are generally reduced to obtain thiner tube sizes, rolling process can achieve this purpose using compression.
Tube rolling is a very precise method of reducing very thin walled or smaller diameter tubes, usually it get a fine surface finish and accurate sizes.
Cold Drawing
Cold drawing is also cold working method to reduces the diameter by pulling the tube through a die, that device inner size is smaller than the tube, in order to pull the tube into the die, the diameter of tube is reduced to desired size to pass through.
Annealing
It is also named as heat treatment, this process soften material to make further processing, and improves the overall metallurgical microstructure of the tube.
Tube is heated to a controled temperate, usually 300 series stainless steel minimum annealing solution is 1040 C, annealing relieve stress and make material suitable redrawing.
Pickling
It is chemical method to clean the tube resulting from cold working or annealing process, generaal using sulphuric acid or nitric acid, putting tube into pickling tank and soaking a right time, not short and not long depending stainless steel grade.
Testing And Inspection
All the material should be tested before shipment as standard or special requirement, there are non-destructive and destrucative tests for option.
Non Destructive Testing
- PMI for material identity
- Visual inspectionDimensional inspection, tolerance
- Eddy Current testing
- Ultrasonic testing
- Hydrostatic pressure testing
Destructive Testing
- Yield Strength, Tensile Strength, Elongation
- Rockwell Hardness testing
- Grain size
- Flattening and flaring testing
Seamless Pipe Advantages
20% Higher Working Pressures
Compared to welded tube, seamless pipe has no longitudinal weld seam, seamless tube has 20% higher working pressures under the same material and size condition.
Heavy Walls
Seamlless pipe can acheive heavy wall pipe for high pressure applications.
Corossion Resistance
Seamless pipe is generally considered to be the most consistent material with the least impurities, because it has no welding seam, and reducing risk on corrosion attack
