Dot steel tubing

By Mikamuro

A DOM Round Steel Tubeis a welded mechanical round steel tube with the internal weld seam removed creating a smooth internal surface. DOM Round Steel Tube has been drawn over a mandrel to produce a tube having more exact dimensional accuracy and tolerances, and a very smooth inside and outside finish.

Pipe Inspection, Testing & Marking

DOM Round Steel Tube is ideal for more stressful applications requiring higher quality, increased mechanical properties, uniformity, strength, and soundness. Total footage ordered will be shipped.

There are some Special pipe inspection tests also carried out on the material when it is going to be used in aggressive environments.

These tests will ensure that pipe material is able to withstand in such aggressive environments also. Some of the tests are. These tests are performed when it is asked by the purchaser in his specification. In Destructive Testing- a sample from the pipe is cut to performed tests. These testing are. The pressure is monitored by the computerizing system. For welded pipe inspection, the test pressure should be held for a time, sufficient to permit the inspector to examine the entire length of the welded seam.

A hydrostatic test can be waived under certain conditions as set in the ASTM standard. During a dimensional inspection, following to be confirmed with standard. Permissible Variations depends on manufacturing standard.

Generally, the thumb rule is that 1 mm per meter is acceptable. However, most purchasers clearly specified a maximum acceptable limit for straightness. Once the pipe is cleared all test and inspection, it is marked as per the standard requirements. Please note that. To prevent the damage during transportation, pipe ends are covered with a cap. Spider supports at the end of the pipe are also installed in Large diameter pipe to protect the circularity of pipe.

Supplementary requirements are optional that the purchaser has to specify along with purchase requisition. Mainly these requirements are related to additional testing of the product such as low-temperature tensile, transverse tensile, restriction on Carbon Equivalent, etc.

Each standard lists these requirements at the end of the standard product requirements. Skip to main content Skip to primary sidebar.

Jan Carmen Rivera - clrivera gibraltar1. Thank you for your continued support.A few years ago, I was introduced to the wonderful world of rust-free copper-nickel tubing, for brake lines. I think the stuff is awesome, but how awesome is it, really?

It can rust out enough to spring a leak in as little as ten years. One alternative is to purchase pre-bent lines, but these can be expensive to purchase, delicate to ship, and sometimes even require removal of major components like a fuel tank to install.

Steel DOM Round Tubing

Sure, you could buy yourself some time by going with with poly-coated steel, but in salt states, that still only buys you a limited amount of time, compared to rust-free options.

But aside from the higher cost which might actually be worth it in the long runstainless steel can be finicky to work with due to the hardness of the material. Copper-nickel tubing, such as Cunifer or NiCoppoffers what appears to be a miraculous alternative.

In fact, its PSI ratings are only a little lower than that of steel, still more than strong enough for brake applications, which typically see a maximum of anywhere from to 1, PSI. In some cases, that number can get as high as 2, Copper-nickel tubing is rust-free. It flares easily, and readily conforms to make a seal when tightened into place. You do pay for it, though. But when you look at the job ahead of you, and the potential lifespan of the tubing, that higher cost can quickly start to look rather negligible.

And it holds up well for its age.

Sound too good to be true? After all, just imagine the consequences of losing brakes! Or springing a fuel leak! Like how some vehicles have wheel bearings that are held in by castle nuts The nickel, iron, and manganese content present in the alloy are key ingredients to roadworthiness, improving fatigue and general strength.

Unfortunately, articles on the subject range from long-form sleep-inducing technical gobbledygook to what almost comes across like a fearmongering upsell opportunity for shops to increase their profits.

Thanks to the limited information available, skepticism about this interior corrosion runs high, especially in this thread. But where is the copper even coming from, anyway? Examination of the inside diameter of a brake line at the braze joint Rather, they all tend to focus on the particles finding their way to the ABS components and wreaking havoc there. So it would seem that whatever corrosion does take place inside these lines, happens at a much slower rate, and a much smaller scale than the exterior rust that steel lines are prone to.

But that relatively small amount is still enough to mess with ABS parts and cause problems. Brake fluid contains corrosion inhibitors that lose their effectiveness with heat and age. But better than any additive, is simply changing that fluid on time, regardless of whatever material your vehicle has for brake tubing.

That probably has more to do with purging moisture from the lines, than it does with flushing copper particles out, though. Need more reasons to keep up on those fluid changes?Pipe size is an industry designation, not the actual size. View information about how to measure threaded and unthreaded pipe and pipe fittings.

In addition to handling low temperatures, these fittings can also withstand higher pressures than other push-to-connect D. Fittings connect to tubing with a push, and an internal gripping ring and O-ring hold the tubing tight. Fittings have a built-in tube support that slips inside the tubing to prevent it from collapsing. To disconnect, push on the release ring and pull the tubing out of the fitting. Fittings are also known as instant fittings. They have good corrosion resistance.

Metric male threads have a gasket to protect against leaks. For technical drawings and 3-D models, click on a part number. Fittings with tube stem insert into the push-to-connect end of another fitting in place of a length of tubing. Through-wall fittings are also known as bulkhead couplings and panel-mount couplings; they mount through your wall or panel to create an inlet or outlet.

Suitable for use in air brake lines, these fittings meet Department of Transportation FMVSS safety standards for low-temperature applications. Also known as instant fittings, they connect to tubing with a push, and an internal gripping ring and O-ring hold the tubing tight. The male threads have an acrylic sealant applied to protect against leaks. Plugs insert into the push-to-connect end of a fitting.
