Is it something to do with chloride stress corrosion cracking, can anybody explain what is chloride stress corrosion cracking.

why ASTM A TP pipe used for dimeneralised water

This guide covers standard specification for seamless, straight-seam welded, and cold worked welded austenitic stainless steel pipe intended for high-temperature and general corrosive service. Pipe having other dimensions is permitted to be ordered and furnished provided such pipe complies with all other requirements of this a32.

They exhibit excellent corrosion resistance to a wide range of corrosive environments. It has excellent corrosion resistance and forming characteristics. The safe operation of oil refineries in the United States is under constant r If required we arrange for packaging also for sea freightsupply plastic caps or protection rings at the pipe ends and organise special marking.

So please participate and share knowledge just as you have in the past.

Impact testing may, under certain circumstances, be required. SS L piping is much costlier and generally not reqd not a service requirement. Question is why TP pipe used for DM water?? Our Overseas Sales Office. Several grades of steel shall conform to the required chemical composition for carbon, manganese, phosphorus, sulfur, silicon, chromium, nickel, molybdenum, titanium, columbium, tantalum, nitrogen, vanadium, copper, cerium, boron, aluminum, and others.

ASTM A312 Grade Tp304

Sensitization is the precipitation of Cr rich carbide M23C6 at grain boundaries, when heated betn C as happens during welding etc. If exact equivalents are needed original specifications must be consulted.


Chloride stress corrosion is a type of intergranular corrosion and occurs in austenitic stainless steel under aatm stress in the presence of oxygen, chloride ions, and high temperature.

We have a full range of expertise for Export Packing. Type Stainless Steel has excellent welding and deep drawing characteristics – it is easy to fabricate, easy to clean and aesthetically pleasing to the eye. Our stock range consists of the following:. Weld annealing is only necessary in applications where stress loads are excessive.

ASTM A312 TP 304 Stainless Steel Seamless Pipe

The steel pipe shall undergo mechanical tests such as transverse or longitudinal tension test and flattening test. Our team of project coordinators communicates all relevant facts about inspection, testing and quality control and assures ASTM A TP Stainless Steel Welded Pipe will be supplied against the agreed terms for packaging and transportation. Our broad product range makes your individual wishes possible and also x312 the extraordinary demands.

All Projects t3p04 careful planning to ensure a good result and correct material selection. If nothing is specified in the customer purchase order, our standard packing style is followed. Historical Version s – view previous versions of standard. Grade H cannot be included in this equation due to the steel’s higher carbon content which is intended for use in elevated temperature applications.

Even t3p04 SS you have to maintain a minimum flow aztm and if there is any stagnancy SS can also get pitted and punctured due to local concentration cell. The stainless steel alloy resists most oxidizing acids and will withstand ordinary rusting though this does not mean that the steel will not tarnish over time.

As a result, Astmm L stainless steel is a sort after material for use in severely corrosive conditions. Vishal Steel will gladly perform any special services that you may require such as cut to length, threading, grooving, etc. NOTICE When migrating the old forums over to our new forums we were unable to retain the identity of the authors, so the old posts will show up as “anonymous”.


Large Diameter Size Tubing Schedule: Combining values from the two systems may result in non-conformance with the standard. In order to guarantee these standards, we are certified in accordance with the strict guidelines of ISO All materials can be prepared for shipping by truck, by bulk vessel or container vessel. Grain size determination and weld decay tests shall be performed.

Our all ASTM A TP Stainless Steel Welded Pipe are tested in accordance to internationally recognized standards or our own more stringent internal test procedures, which is developed considering a132 harsh field conditions. asym

Feel free to contact! DM Water is often callled ‘Hungry Water” as it invites metals in it. All materials can be prepared for shipping by truck, fp304 bulk vessel or container vessel. ASTM A Grade Tp are known to deliver exceptional performance and are generally developed for meeting the demands. Physical properties of grade stainless steel in the annealed condition.

TP has a carbon 0. These grades of austenitic Stainless Steels are the most versatile and widely t304 Stainless Steels. Great care is taken during operation and transportation.

Discussion Forums – The Hendrix Group. For example, materials with chromium or nickel content outside the AISI ranges, and for material with carbon content exceeding 0.

Page 1 of 1. Grade L is more resistant to carbide precipitation and can be heated into the above temperature range.

It can be used as a fabricated material where high temperature petroleum gases or steam production gases are stored such as pressure vessels. These comparisons are approximate only. However, by this process DM water will be degraded.
