Overview

Stainless Steel Tube for Condenser is made by heating a round tube billet and producing it by cold rolling, cold drawing or hot extrusion. It is made of high quality stainless steel but is available in various versions depending on the actual metal content. Our product is a seamless tube with a polished, smooth and burr-free surface. It is available in a wide range of diameters and lengths to suit different needs. Our Stainless Steel Tube for Condenser is used in the chemical, mechanical, electronic and electrical industries.

Our Stainless Steel Tube for Condenser is resistant to high temperature steam, impact corrosion and corrosion. In addition, it is resistant to scaling, staining and corrosion. Our products have a long service life, reduce maintenance time and save money. Furthermore, it is very safe and reliable to use because of its good tube fitting process and direct tube replacement. In short, you will not be disappointed if you choose our products.

Standards: ASTM A213, ASME SA213, ASTM B163, ASME SB163, EN10216-5, JIS G3463, DIN17458
Specification: OD 6mm to 1016mm; WT 0.5mm to 30mm; Length Max 25m.
Tests: all tubes should be hydro static tested, non-destructive tested (ET and/or UT).

The chemical composition of part of above materials which could be used for heat exchanger tubes are as following. This table list material from TP316/S31600 to N8800/800. Other material composition would be listed in other products.

Manufacture and Condition—Tubes shall be made by the seamless process and shall be either hot-finished or cold-finished, as specified. Grade TP347HFG shall be cold finished.

Heat Treatment:

Ferritic Alloy and Ferritic Stainless Steels—The ferritic alloy and ferritic stainless steels shall be reheated for heat treatment in accordance with the requirements of Table 3. Heat treatment shall be carried out separately and in addition to heating for hot forming.

Austenitic Stainless Steels—All austenitic tubes shall be furnished in the heat-treated condition, and shall be heat treated in accordance with the requirements of Table 3. Other than for Grades S30815, S30942, S31272, S33228, and H Grades, seamless tubing immediately following hot forming may be individually quenched in the water or rapidly cooled by other means, provided that the temperature of the tubes after hot forming is not less than the minimum specified solution temperature (direct quenched). For H grades, as well as Grades S30815, S30942, S31272, S33228, and S30432, the tubes shall be reheated to the specified solution treatment temperature for the required time before quenching.

If any controlled structural characteristics are required, these shall be so specified in order as to be a guide as to the most suitable heat treatment.

Unstraightened Tubes

When the purchaser specifies tubes unstraightened after final heat treatment (such as coils), the minimum yield strength of Table 4 shall be reduced by 5 ksi [35 MPa]. S3.2 On the certification, and wherever the grade designation for unstraightened tubing appears, it shall be identified with the suffix letter “U” (for example, 304-U, 321-U, etc.).
