Heat resistant stainless steel pipe

on
The auction is for 6 metre length of prime quality grade 409 stainless steel tubing with a 1.2mm wall thickness x 38.1mm (1 1/2") diameter.

This grade of stainless steel is suitable for the manufacture of vehicle or other motor exhausts.

These stainless steel have the good heat-resisting performance, is suitable in the steam environment or 550℃ and the above temperature.

  • 310S Stainless steel is a combination of good strength and corrosion resistance in temperature up to 2100oF (1149℃). Due to its relatively high chromium and nickel content it is superior in most environments to 304 or 309 stainless.
  • 309S High corrosion-resistant, chromium nickel grade with carbon limited to .08 to reduce carbon precipitation during welding. Maximum Recommended Service Temperature Continuous 1100℃ /Intermittent 980℃
  • 304H the carbon content is controlled to a range of 0.04-0.08 to provide improved high temperature strength to parts exposed to temperatures above 800°F (427℃)
  • 321H advantage an excellent resistance to intergranular corrosion following exposure to temperatures in the chromium carbide precipitation range from 800 to 1500°F (427℃ to 816°C).
  • 347H in higher elevated temperature allowable stresses for these stabilized alloys for ASME Boiler and Pressure Vessel Code applications. The 321 and 347 alloys have maximum use temperatures of 1500°F (816°C)

Heat exchanger Tubes are used in all types of process industries. Characteristic requirements are: bead worked weld, fixed lengths and extensive testing.

In order to meet the demand for rapid delivery, we have a strip stock with both standard and special grades of steel in the most common thicknesses.

We supply both seamless and welded tubes which meet the requirements for shell and tube heat exchangers:

Size range 6.35mm - 76.2mm OD x 0.91mm – 3.25mm wall thickness

Heat exchanger tubes are supplied in Standard Wire Gauge (SWG) or Birmingham Wire Gauge (BWG)

Popular grades: 1.4306 (304L), 1.4404 (316L)

Steel pipe world standards

Pipe manufacturing refers to how the individual pieces of pipe are made in a pipe mill; it does not refer to how the pieces are connected in the field to form a continuous pipeline. Each piece of pipe produced by a pipe mill is called a joint or a length (regardless of its measured length). In some cases, pipe is shipped to the pipeline construction site as “double joints”, where two pieces of pipe are pre-welded together to save time. Most of the pipe used for oil and gas pipelines is seamless or longitudinally welded, although spirally welded pipe is common for larger diameters. 1.

Orifice Flanges

Orifice flange for run installation should be so constructed, machined and attached to the that the inner surface of the passage extends through the orifice flange so that there is no recess at the orifice plate. Orifice flanges are used instead of the standard pipe flanges when orifice plate or flow nozzle is used. The basic purpose for this is to measuring the flow rate of either gases or liquids in the respective pipeline. These flanges are used in various industrial applications and are available in various sizes and materials. Orifice Flange manufacturer Sunny Steel supplies Orifice Flanges, Plate Flanges, Datasheets and dimensional information ANSI 300 Flange - Orifice, Weld Neck, ANSI Class 300, B16.36 (in) ANSI 400 Flange - Orifice, Weld Neck, ANSI Class 400, B16.36 (in) ANSI 600 Flange - Orifice, Weld Neck, ANSI Class 600, B16.36 (in) ANSI 900 Flange - Orifice, Weld Neck, ANSI Class 900, B16.36 (in) ANSI 1500 Flange - Orifice, Weld...
