Length:3m,5.8m,6m,9m,12m.
Surface Treatment:Polished , cold drawn , cold rolled, honed, anneal.
Packing:1.bundle packing. 2.wooden case 3. pipe caps as customer request
Test:SGS,BV,TUV or as customer required.
Features:
1.Smaller diameter
2. The outside diameter dimension precision (tolerance range) is strict, the inside and outside surface smoothness, roundness, straightness are good,
3.High precision can accept small batch fabrication
4.The cross area of steel pipe is more complex
5.The steel pipe has better performance and the metal is relatively dense.
Application:
Cold Drawn Seamless Steel Tubes For Mechanical Use has the advantages of high precision and smoothness, no air oxide layer on the inner and outer walls, high pressure, no deformation during cold drawing, flaking, flattening without cracks, etc. For the reason the cold-drawn seamless tube is mainly used for the production of pneumatic or hydraulic products, such as seamless steel tube for cars, crude oil drilling tools, etc. Shaped tubes in cold-drawn seamless tubes can be used for a wide variety of parts, items and mechanical.
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
10. Chemical industry, building industry, environment industry and more
Delivery condition: hot rolled, annealed, normalized, quenched and tempered
Packaging:
1. Bundle packing
2. Beveled end or plain end or varnished as per buyer's required
3. Marking: as per customer's requests
4. Painting varnish coating on the pipe
5. Plastic caps at ends
