Seamless Butt Welding 45° Length Radius Elbow 6”SCH-40 ASTM N08825 Alloy 825

Introduction

Elbow is a commonly used connecting pipe fitting in plumbing installation. It is used for the connection at the bend of the pipeline and to change the direction of the pipeline.

Other names: 90 ° elbow, right angle bend, love bend, stamping elbow, pressing elbow, machine-made elbow, welding elbow, etc.

Purpose: connect two pipes with the same or different nominal diameter to make the pipeline turn 90 °, 45 °, 180 ° and various degrees.

Bending radius less than or equal to 1.5 times of pipe diameter belongs to elbow, and bending radius greater than 1.5 times of pipe diameter belongs to elbow

Overview and features

The comprehensive performance of the alloy is reflected in the Nuclear Combustion dissolver with various corrosive media, such as sulfuric acid, nitric acid and sodium hydroxide are treated in the same equipment. It is used in various industrial fields with service temperature not exceeding 550 ℃, such as heating pipe, container, basket and chain for sulfuric acid pickling plant, seawater cooling heat exchanger, marine product pipeline system, acid gas environment pipeline, heat exchanger in phosphoric acid production, evaporator, washing and impregnation pipe, air heat exchanger in petroleum refining, food engineering, chemical process, flame retardant alloy for high-pressure oxygen application, etc.

N08825 process performance and requirements

The alloy heating environment contains sulfur, phosphorus, lead or other low melting point metals, and the nicrofer 6023 / 6023h alloy will become brittle. Impurities come from marked paint, chalk, lubricating oil, water, fuel, etc. The sulfur content of fuel should be low. For example, the impurity content of liquefied gas and natural gas should be less than 0.1%, the sulfur content of urban gas should be less than 0.25g/m3, and the sulfur content of petroleum gas should be less than 0.5%.
