What’s the Manufacturing for Processes Welded Tube and Pipe?
Steel pipes are made by two different processes. The overall production method for both processes involves three steps.
Table of Content
隐藏
First, raw steel is converted into a more workable form. Next, the pipe is formed on a continuous or semicontinuous production line. Finally, the pipe is cut and modified to meet the customer’s needs.
Ends of Pipes
For the ends of pipes are 3 standard versions available.
- Plain Ends (PE)
- Threaded Ends (TE)
- Beveled Ends (BE)
The PE pipes will generally be used for the smaller diameters pipe systems and in combination with Slip On flanges and Socket Weld fittings and flanges.
The TE implementation speaks for itself, this performance will generally used for small diameters pipe systems, and the connections will be made with threaded flanges and threaded fittings.
The BE implementation is applied to all diameters of buttweld flanges or buttweld fittings, and will be directly welded (with a small gap 3-4 mm) to each other or to the pipe.
Ends are mostly be beveled to angle 30° (+ 5° / -0°) with a root face of 1.6 mm (± 0.8 mm).
Length of Pipes
Piping lengths from the factory not exactly cut to length but are normally delivered as:
- Single random length has a length of around 5-7 meter
- Double random length has a length of around 11-13 meter
- Shorter and longer lengths are available, but for a calculation, it is wise, to use this standard lengths;
- other sizes are probably more expensive.
Packing:
- Packed in wooden crates, wrapped in plastic, and suitably protected for sea-worthly delivery or as requested.
- Both ends of each crate will indicate the order no., heat no., dimensions, weight and bundles or as requested.
Delivery:
- Pipes are supplied in hexagonal bundles or round bundles tied with steel strip.
- Weight of bundle – up to 5000 kg upon request of customer.
- Each bundle is furnished with three tags.
