High Grade Steel Api 5l Tube Rolling Mill 415v

Tube Conveyor Line Petroleum And Gas Oil Casing High-Grade Steel Pipe API 5L Standard Tube Mill

Product Introduction

Designed for the most precise fabrication of cold/hot-rolled coil, galvanized coil. The ERW pipe mill machine can provide the tightest tolerances for production. Produced round/square/rectangle pipe can be used in metallurgy, construction, transportation, machinery, automobile industry, and more.

ERW pipe mill is used to produce API, EN, ASTM, GB/T, etc pipe to transport water, gas, and oil, also can produce construction pipe.

ERW pipe mill is used to level the fixed strip after slitting line, and enter it to forming machine, bend to the pipe by roller, melt the strip edges through the High-frequency current, squeeze and weld the pipe by the squeeze roll. The high-frequency pipe mill is also called the ERW pipe mill.

API Pipeline Process

Loading coil - Uncoil - Straighten head - Ultrasonic plate testing - Shearing and butt welding - Spiral loop - Edge planing - Forming - High-frequency welding - Remove inside and outside the burr - Ultrasonic weld seam inspection - Polishing - Intermediate frequency annealing - Air cooling and water cooling - Correct reverse - Sizing finishing - Turkey head straightening - Length cut - Sampling test - Straightening - Tube end facing - Hydraulic test - ultrasonic flaw detection - Coating - Marking - Packaging - Warehousing

Features of Production Line:
1. High strength, high toughness, and corrosion resistance of raw materials;
2. The equipment has high strength, high precision and occupies large ground;
3. The equipment has the characteristics of fast roll change without dismantling the main shaft and archway, and the common rate of roll mold is high;
4. Multi-procedure inspection and flaw detection are required; The finishing quality of the pipe end is required to be high.
5. Production of high steel grade, large diameter, large wall thickness steel pipe products.
