Pipes are first and foremost produced through an extrusion process . The raw material is feeded into the extruder via a hopper and a gravimetric or volumetric control system. Inside the extruder barrel the material is heated up to the melting point around 200°C by electricity and the friction in the screw system.

What are the 4 manufacturing processes for steel pipe?
The slabs are reheated and processed into plate and coils. There are four methods used to produce steel pipe: Fusion Weld, Electric Resistance Weld, Seamless and Double Submerged Arc Weld . One process for producing pipe is Fusion Weld, sometimes called “Continuous Weld” and is produced in sizes 1/8” to 4-1/2”.
Which material is made by PVC pipes?
Polyvinyl Chloride or PVC is a thermoplastic material derived from common salt and fossil fuels. The pipe material has the longest track record of all plastic materials. The first PVC pipes were made in the 1930’s.
What is plastic pipe used for?
Plastic pipework is used for the conveyance of drinking water, waste water, chemicals, heating fluid and cooling fluids , foodstuffs, ultra-pure liquids, slurries, gases, compressed air, irrigation, plastic pressure pipe systems, and vacuum system applications.
For which of the following process tubes are manufactured?
Mass production of seamless tubes is done by the extrusion process . Extrusion is a compressive deformation process in which a block of metal (heated billet or slug of metal) is squeezed through an orifice or die opening in order to obtain a reduction in diameter and increase in the length of the metal block.
How tubes are manufactured?
To manufacture Oil Country Tubular Goods, massive steel billets are heated to the forming temperature and formed into shells. These shells are then rolled over a mandrel on the push bench into a mother tube/ hollow. In the stretch reducing mill the tubes get their final customized dimension and wall thickness.
What are primary processes in manufacturing?
In general, primary processes convert raw material or scrap to a basic primary shaped and sized product . Secondary processes further improve the properties, surface quality, dimensional accuracy, tolerance, etc. Advanced processes usually (but not necessarily) manufacture desired products at one step.
What are the 3 types of processes?
- Operational process.
- Supporting process.
- Management process.
What is the best manufacturing process?
Incorporating robotics and automation into plant floor processes is regarded as a best practice for manufacturing operations for several reasons. Automation can result in faster project completion times and improved quality by minimizing the need for human intervention.
