Three constraints affect the cross-sectional dimensions of welded tube:

1 Outside diameter (OD)

2 Gauge (wall thickness)

3 Inside diameter (ID)

An welded tube manufacturer can control the OD and gauge of the tube. Since the tube is manufactured from the outside by a series of rolls that ultimately produces the final OD size of the tube, the ID varies by the combination of the final OD and gauge. Tight tolerance tubing reduces ID variation compared to that of conventional tubing produced to American Society for Testing & Materials (ASTM) standard 513. For fabricators, this reduction helps to provide improved quality, reduced scrap, and the possible elimination of processing steps.

We can classify the seamless steel pipes as cold drawn seamless pipe and hot rolled seamless pipe due to the producing process. It is widely used in bolier water tube, fire tube, superheater tube , Air preheater pipe etc.

Production Flow:

1. Steel billet → heating → punching → head making → annealing → pickling → copper plating → cold drawing → semi-finished pipes → heat treatment → straightening → water pressure test → labeling → warehouse entry.

2. Round billet→ pickling→ cut off→ heating→ piercing→ pointing→ pickling→ cold-drawing (cold-rolling) → semi-finished pipe→ heat treatment→ physical chemistry test→ straightening→ corps end cutting off→ surface and size inspection→ eddy current inspection→ UT testing→ marking/painting/bundling→ warehouse/shipping

Each step is under strict control to ensure you a high quality pipe.

Classifications of Cold Drawn Seamless Pipe:

In our company, we mainly produce the cold drawn steel pipes in modus of SCH40, SCH80 and SCH160 with the size of 6m.

We can manufacture cold drawn pipe as follows:

1.common seamless tube

2.low pressure boiler steel pipe

3.high pressure boiler tube

4.alloy-steel tube

5.antirust cold drawn steel pipe

6.petroleum cracking pipe


Applicable to boiler tube etc.
