The cold-drawn seamless pipe is adopted, in which the round steel is perforated to become a capillary, and the round steel is finally turned into a steel pipe by the operation of pickling, starting and cold-drawing, etc. This is called cold-drawing pipe, and the pipe pulled out by cold-drawing process is also called cold-drawing tube.

The production process of cold-drawn seamless steel pipe is as follows:
round tube billet → heating → perforating → heading → anneal → pickling → oiling (copper plating) → multi-pass cold drawing (cold rolling) → billet tube → heat treatment → straightening → hydrostatic test (flaw detection) → marking → warehousing.
Application:
Cold drawing Seamless pipe, the products are widely used in municipal engineering, water supply pipeline, sewage discharge, heating network, gas network, coal mine, ventilation pipeline, construction engineering, steel structure, piling, bridge, wharf and other fields.
Tests we apply to the tubes:
1. Chemical composition analysis
2. Mechanical properties (tensile strength, yield strength, elongation, hardness)
3. Technological test (flattening test, flaring test, bending test, hydraulic pressure test)
4. Surface quality detection
5. Eddy-current examination
6. Visual test
Applications:
1. Low and middle pressure fluid transportation pipeline
2. Casing pipe
3. Low and medium pressure boiler seamless steel pipe
4. High pressure boiler seamless steel pipe
5. Carbon seamless steel pipe for ship
6. Seamless steel pipe used in high pressure chemical fertilizer equipment
7. Petroleum and natural gas industry
8. Steel pipe for heat exchanger
9. Used for diesel engine
