Specifications
1 Definition: welded steel pipe is also called welded pipe which is steel pipe formed by welding the curled steel plates or strip steel, with general fixed length of 6m.
2 Production process: raw material uncoiling – flattening – end cutting and welding – looping – molding – welding – internal/external removal of welding beads – precorrection – inductive heat treatment – sizing and straightening – eddy current testing – cutting – water pressure inspection – acid pickling – final inspection (strict control) – packing – delivery
3 Category:
Production methods:
a. Process – electric arc-welded pipes, resistance welded pipe (high frequency, low frequency), gas-welded pipes, furnace butt-welded pipes
b. Welding seam – straight welded pipes, spiral welded pipes
4 Wall Thickness
Thin-wall steel pipes, thick-wall steel pipes
5 End Shape
Circular welded pipes and specially-shaped (square, flat, etc.) welded pipes
6 Length: 6m -12m(capable of being customized and processed according to customer requirements)
7 Surface:Prime quality (bared, oiled, color paint, 3LPE, or other anti-corrosive
treatment)
8 Packing: bundling, nude packing, or packing according to customer requirements
9 Carbon Steel Straight Welded Pipes
Weight (kg) per meter
Note: d (outer diameter); t (wall thickness)
10 Features:
Straight welded pipes feature simple production process, high production efficiency, low cost and high development speed.
The intensity of spiral welded pipes is generally higher than that of straight welded pipes; welded pipes with larger pipe diameters can be produced by relatively narrow blanks; welded pipes with different pipe diameters can be produced blanks with the same width. However, spiral welded pipes have the length increase of 30~100%, as well as lower production speed compared with straight welded pipes with the same length.
11Application:
structure, electric power transmission tower projects, piling, water, oil & gas pipeline
engineering, mechanical industry, municipal projects, roads and its auxiliary facilities, etc.
