Seamless Butt Welding Reducer 22”*12” SCH-20 Alloy 600 ASTM/UNS N06600

Introduction

Reducer, also known as reducer, is one of the chemical pipe fittings, which is used for the connection of two different pipe diameters. It is also divided into concentric reducer and eccentric reducer.

The big and small heads whose center is in a straight line are called concentric big and small heads. The commonly used forming process is reduced diameter pressing, expanded diameter pressing or reduced diameter plus expanded diameter pressing. Stamping can also be used for reducing pipes of some specifications.

Overview and features:Alloy K-600

UNS n06600 alloy has corrosion resistance to various corrosive media. The composition of chromium makes the alloy have better corrosion resistance than nickel 99.2 (alloy 200) and nickel 99.2 (alloy 201, low carbon) under oxidation conditions. At the same time, the high nickel content makes the alloy have good corrosion resistance under reducing conditions and alkaline solution, and can effectively prevent chloride iron stress corrosion cracking. Alloy 600 has good corrosion resistance in organic acids such as acetic acid, acetic acid, formic acid and stearic acid, and medium corrosion resistance in inorganic acids. High purity water used in primary and secondary recycling in nuclear reactors has excellent corrosion resistance. The outstanding performance of 600 is that it can resist the corrosion of dry chlorine and hydrogen chloride, and the application temperature is 650 ℃. At high temperature, the alloys as annealed and solution treated have good anti-oxidation spalling properties and high strength in air. The alloy can also resist ammonia, nitriding and carburizing atmosphere, but when the redox conditions change alternately, the alloy will be corroded by some oxidizing media

application area

1. Production of organic or inorganic chlorides and fluorides: resistance to chlorine and fluorine corrosion

2. Nuclear reactor

8. Curved neck bottles and parts in heat treatment furnace, especially in carbonization and nitriding atmosphere

4. Alloy 600 is recommended to be used in the application of catalytic regenerator in petrochemical production above 700 ℃ to obtain a long service life
