Our company is famous for manufacturing bright high-precision seamless steel tubes 

for transmission of fluids for years, it is one of the main products by our company. 

This type of products is subject to DIN standard, and equipped with strict quality 

assurance system and enterprise inner-control dimension standards, 

so as to make sure that the quality can be satisfied by clients.

The seamless precision steel tubes can be used for a wide range of precision mechanical spare 

for car and cylinder accord to standard DIN2391/ EN10305-1/ GB/T3639-2009.

Specifications of Precision Carbon Steel Tube:

1. Diameter: 4mm~60mm

2. Length: 3m, 6m, 9m or customized

3. Thickness: 0.5mm~8mm

4.Standard: DIN2391, DIN17175, EN10305, ISO8535, GB/T8713, GB/T8163, etc.

SAE1010, SAE1020, ST35, ST37.4, ST52.4, etc.

5. Surface: oiled, polished and electrophoretic paint.

Packaging of Precision Carbon Steel Tube :

Shanghai Metal Corporation Products are packed and labeled

according to the regulations and customer's requests.

Clear labels are tagged on the outside of the packages

for easy identification of the product I. D. and quality information. 

In bundles tied with steel strips.

External packing by wooden cases if the wall thickness/OD ratio is low.

Oil-coating is generally necessary especially for export.

Application of High Precision Steel Tube

1.    Hydraulic system

2.    Automobile

3.    Compression ignition engine

4.    Nested Card connector

5.    Construction machine vehicles.

Used in hydraulic & pneumatic cylinder ,automobile and other mechanical device.

Feature: high precision and high brightness, the inner and outer surface of the tubes

have high cleanness without oxid, mechanical properties of the final tubes

also come out excellent, promising no leakage under high pressure, no deformation

after cold-bent and no cracks when flaring and flattening, ensuring the efficient operation in all service.
