MicroGroup, Inc., Minitul

United States

MicroGroup is a leading worldwide distributor of small-diameterthin walled tubing offering quick shipments from over 7, 000, 000 feet (2, 100, 000 meters) in stock one of the worlds largest inventories available in alloy, 304, and 316 stainless steel tubing, both welded and seamless. Click on any stock material in the menu immediately above for detailed information.Stock stainless steel and other alloys are typically manufactured to an OD and wall dimensions. To purchase standard stock tubing please visit our Online Store For non-stock dimensions see Quick Turn, Custom Sized Tubing.

MicroGroup typically stocks seamless 304 stainless steel metric tubing and 316 stainless steel metric tubing, usually in the annealed temper condition manufactured to OD and wall dimensions. Metric tubing is generally used with standard metric compression fittings and other commercial applications that require corrosion resistance and strength.

MicroGroups comprehensive range of drawing, centerless grinding and straightening equipment can alter the OD, ID andor wall thickness of tubing to achieve custom sizes that are not stocked while maintain short lead times. Tube Drawing MicroGroup tube formingdrawing equipment (shown at right) reduces the ID and OD of stock tubing to custom dimensions, andor can increase its tensile strength through the reduction process. Custom tubing can be sourced almost instantly from over 7, 000, 000 feet (2, 100, 000 meters) of tubing in inventory, to meet your ID requirements from .005 to 1, with ID tolerances as low as .001 on some larger sizes, and .0005 on smaller hypodermic tube sizes. MicroGroup can draw any grade of stainless steel tubing from 302 to 455, and can also draw copper, nickel, brass, Inconel and other tubing. MicroGroup offers two methods of tube drawing (Sink Drawing and Plug Drawing) and has the ability to create custom shapes using these methods. SinkDrawSink Drawing reduces the diameter of a tube by pulling it through a die without the use of a mandrel. In sink drawing, the ID is determined by the OD and wall thickness of the pre-drawn tube. This is the fastest form of drawing, and suitable for drawing of thick walled tubing, as well as drawing of tubes smaller than .062 OD where using a mandrel is not possible.

Fractional tubing is often used in commercial applications that require corrosion resistance and good strength. MicroGroup fractional tubing starts at 132 OD and is generally stocked in 304 stainless steel and 316 stainless steel but is also available in many other metals and alloys in a variety of specifications. It is typically stocked in the annealed temper condition and is available as welded tubing (welded and drawn) or seamless tubing.Fractional stainless steel is normally available in commercial ratings such as ASTM-A-269, DFARS, ROHS, Mil-T-8504 and ASM-5570. Note that MicroGroup offers the in-house capability to produce custom sizes and hold the chemical composition of the starting specification to reduce lead times.

Hypodermic tubing is welded and drawn to tight OD and ID tolerances, and is sold and stocked in gauge sizes.MicroGroup maintains both 304 stainless steel and 316 stainless steel tubing in stock, typically in full-hard temper condition. 304 stainless steel hypodermic tubing is stocked in all sizes and wall thicknesses. 316 stainless steel hypodermic tubing is stocked in all gauges but primarily stocked in Regular Wall (RW) and Thin Wall (TW). MicroGroup hypodermic tubing is ideal for medical and industrial components applications that require strength, uniformity, and corrosion resistance. Not manufactured for pressure service. Wide selection, economical and quick delivery.
