A815 UNS S32750 Long Radius Buttwelding Pipe Fittings Stainless Steel WELDING EQUAL 90 Degree Elbow

Introduction

Elbow materials include cast iron, stainless steel, alloy steel, malleable cast iron, carbon steel, non-ferrous metals and plastics. The ways to connect with the pipe are: direct welding (the most common way) flange connection, hot melt connection, electrofusion connection, threaded connection and socket connection, etc. According to the production process, it can be divided into: welding elbow, stamping elbow, hot pressing elbow, push elbow, casting elbow, forging elbow, clip elbow, etc. Other names: 90° elbow, right-angle elbow, love and bend, white steel elbow, etc.

Stainless steel elbow

The main difference between stainless steel elbows and carbon steel elbows is the difference in material, and the chemical composition it contains will keep the surface of the elbow from rusting and corroding for a long time. According to the standard production can be transformed into:

1. According to the manufacturing standard, it can be divided into national standard, ship standard, electric standard, water standard, American standard, German standard, Japanese standard, Russian standard, etc.

2. According to the production method, it can be divided into pushing, pressing, forging, casting, etc.

90° stainless steel elbow is mainly used as a connecting pipe fitting in pipeline installation, which is used for the connection of pipeline bends. Connect two pipes with the same or different nominal diameters to make a 90° turn.

Stainless steel

It is usually formed by adding a high proportion of Cr, Ni and other alloys on the basis of carbon steel, and the content ratio can reach more than 20%. Common steel grades are: 304, 304L, 321, 316, 316L, 1Cr18Ni9Ti, 0cr18ni9. The first several steel grades represented by numbers are Japanese and American steel grades, and the last one (1Cr18Ni9Ti) is the domestic steel grade representation method.

Characteristics of stainless steel: The strength and toughness index are the best among all kinds of steel. Its most prominent advantage is corrosion resistance. Stainless steel must be used in highly corrosive occasions such as chemical papermaking. Of course, the cost is also high!
