ASTM B729 Tubing

Manufacturer, Supplier and Exporter of ASTM B729 Tube, ASTM B729 Tubing, ASTM B729 Pipe, ASTM B729 UNS N08020

We, Steel Tubes India, are a world class manufacturer and supplier of ASTM B729 Pipe Tube and these pipes and tubes are available with us in lengths lying within 13,500 mm and sizes ranging between 6.00 mm OD to 914.4 mm OD. These pipes/tubes can be procured from us in grades of UNS N08026, UNS N08024 and UNS N08020. The thicknesses of these tubes that are available with us are 0.3 mm – 50 mm, SCH 80, SCH 5, SCH 160, SCH10, SCH 80S, SCH 40 and SCH XXS. These pipes/tubes can be obtained from us in two types, namely Seamless Pipes and Seamless Tubes. This alloy goes by another name also and that is - Carpenter 20.

Alloy 20 Tube has far greater resistance to seawater, as compared with Grade 316 stainless steel. In most environs, ASTM B729 Alloy 20 tubes display very good resistance to general corrosion. These pipes/tubes also have superb resistance to localized corrosion, inclusive of the likes of crevice corrosion, pitting and inter–granular. At a temperature of up to 150 °C, such pipes and tubes can also resist chloride stress corrosion cracking. This alloy ensures very good protection from corrosion and as such it is used in many industries and applications such as plastic manufacturing, pulp and paper industry, off-shore oil drilling, chemical substances, energy generation, petrochemicals, food production, pharmaceutical manufacturing, sea water equipment, etc.

ASTM B729 N08020 performs very well in environs in which austenitic grades have premature failure. This alloy also prevents chloride ion rust and pitting. In the specification of ASTM B729 UNS N08020, is covered the standard grades of seamless pipes and tubes such as UNS N08024, UNS N08026 and UNS N08020. ASTM B729 is an alloy of chromium-nickel-molybdenum stainless-steel and pipes and tubes that are made from this material are designed for use in applications and processes that use sulfuric acid. The copper content in this material protects it from sulfuric acid.
