Item specifics


Spiral steel pipe will strip into the pipe unit, by the multi-channel roller rolling, the strip is formed gradually rolled up, round tube blank gap, adjusting the extrusion roller press quantity, make the weld gap control in 1~3mm, and the welding ends Qi Ping.

1 if the clearance is too large, is caused by proximity effect to reduce eddy current heat, deficiency, weld intergranular bonding defects caused no fusion or cracking.

2 if the gap is too small will cause the proximity effect increases, excessive heat caused by burning or welding, weld; weld after extrusion, rolling after the formation of pits, affecting the quality of the weld surface.

Two edge heating tube to the welding temperature, the squeezing roller, the formation of metal grain common mutual penetration, crystallization, eventually to form a solid weld. Spiral steel pipe if the extrusion pressure is too small, the number of common crystal formation is small, the decline in metal welding seam strength, after the stress cracking; if the extrusion pressure is too large, will make the molten metal is extruded weld, not only reduces the strength of welding seam, but also a lot of inside and outside burr, even causing welding lap seam etc. defect.

5) Length: 6M~14M, R1, R2, R3 length can be manufactured by customers' requirements.

2. Abstract:
P110 Oil Casing is a premium form of corrosion protection for some of the most severe chemical and abrasive environments. Natural and butyl rubber linings withstand a variety of high-concentration acids and are the optimum choice for high heat and abrasive environments. Additionally, the elasticity of a rubber lining easily accommodates thermal expansion and contraction as well as vibration.

3. Features:
1) The chemical properties are stable, and the characteristics of high heat-resistance and anticorrosion are also excellent;
2) The impact resistance is strong due to the outer protective layer of steel;
3) Pipes is connected with flange, and easy to installation

4. Application:
Protecting oil/gas tube, and guarantee oil/gas well's nominal operation.
