Seamless Butt Welding Straight Tee 22”*22” SCH-STD Alloy 400 ASTM/UNS N04400

Introduction

It is generally a professional term. Tee is a pipe fitting and pipe connector, which is used at the branch pipe of the main pipe. Equal diameter tee is a kind of tee. There are two kinds of tee: General equal diameter tee and reducing tee. It is named because the three ends can be connected with the pipe.

Equal diameter tees are widely used in the construction and maintenance of petrochemical, petroleum and natural gas, liquefied gas, chemical fertilizer, power plant, nuclear power, shipbuilding, papermaking, pharmaceutical, food hygiene, urban construction and other industries. The pressure of this kind of pipe fitting is high in industry, and the maximum pressure can reach 600kg. The pressure of water pipe in life is low, generally 16KG

Overview and features:Alloy 200

Alloy 400 is a nickel copper alloy (about 67% ni-23% Cu), which is resistant to seawater and steam, salt and corrosive solutions at high temperatures. Alloy 400 is a solid solution alloy that can only be hardened by cold work. The nickel alloy has good corrosion resistance, good weldability and high strength. The low corrosion rate in fast flowing salt water or seawater, the excellent resistance to stress corrosion cracking in most fresh water and its resistance to various corrosion conditions lead to its wide use in marine applications and other non oxidizing chloride solutions. This nickel alloy is particularly resistant to hydrochloric acid and hydrofluoric acid during degassing. As expected by its high copper content,

Alloy 400 has good mechanical properties at sub zero temperature and can be used at temperatures up to 1000 ° F. its melting point is 2370-2460 ° F. However, alloy 400 has low strength in the annealed state, so various tempering can be used to increase strength.
