EN10305 Standard Cold Drawn Seamless Steel Pipe For Hydraulic Equipment

Outer Diameter:16MM-219MM

Thickness:2.5MM-40MM

Standard: EN10305

Cold drawn steel pipes are precision cold-drawn seamless pipes with high dimensional accuracy and good surface finish for mechanical structures and hydraulic equipment. The use of precision seamless pipes to manufacture mechanical structures or hydraulic equipment can greatly save machining hours, improve material utilization, and help improve product quality.


Dimension Tolerance

I.D tolerance (mm) O.D tolerance (mm) I.D Roughness (µm) Straightness (mm/meter)
H7-H9 -/+0.5% 0.10-0.80 0.2-0.80

Size Deviation

Deviation level ​Standardized Outer Diameter Tolerance
D1 ±1.5%. Minimum±0.75 mm
D2 ±1.0%. Minimum±0.50 mm
D3 ±0.75%. Minimum±0.30 mm
D4 ±0.50%. Minimum±0.10 mm

Product Features


1. The outer diameter is smaller.
2. High precision and small batch production
3. The cold drawn (rolled) finished product has high precision and good surface quality.
4. The cross-sectional area of the steel pipe is more complicated.
5. The performance of the steel pipe is more superior, and the metal is relatively dense.

Delivery Conditions

1. BK (+C) No heat treatment after last cold forming process.

2. BKW (+LC) After last heat treatment there is a light finishing pass .

3. BKS (+SR) After the final cold forming process the tubes are stress relieve annealed.

4. GBK (+A) After the final cold forming process the tubes are annealed in a controlled atmosphere.

5. NBK (+N) After the final cold forming process the tubes are annealed above the upper transformation point in a controlled atmosphere.

Production Process

Different processing methods and corresponding auxiliary procedures are selected according to the processing performance of the metal, the size of the pipe, the quality requirements, and the investment and benefits. The basic processes of cold-rolled and cold-drawn pipes are:

(1) pipe material supply, the pipe materials used are hot-rolled finished pipes or semi-finished pipes, extruded pipes and welded pipes;

(2) pipe material preparation, including inspection, bundling, acid Washing, cleaning, rinsing, neutralizing, drying, lubricating, etc.;

(3) Cold working (cold rolling or cold drawing);

(4) Finishing of finished products includes heat treatment of finished products, straightening, sampling, cutting heads and tails, inspection ( Manual inspection and various flaw detection), hydraulic test, oiling, packaging, storage, etc. Different products have different finishing contents.

Application

1. Automotive and mechanical pipes
2. Petroleum cracking pipes
3. High Pressure Boiler Pipe
4. Low and middle pressure fluid transportation pipeline
5. Chemical fertilizer equipment pipe
