Stainless Steel 45 Degree Elbow

Stainless Steel 45 Degree Elbow is a pipe fitting that is shaped at a 45 degree angle. This elbow can be used to change the direction of flow in a piping system so that it is at a 45 degree angle. It is usually used in industrial fields, such as chemical, petroleum, paper and other piping systems, for connecting and steering pipes. It has excellent performance and ensures the stability and reliability of the piping system..

Product Introduction

45 degree elbow is second common use after 90 degree elbow.

45 degree elbow of long radius

The pipe elbow is mounted between two pipes so that the fluid direction can be changed to 45 degrees. Compared to 90 degree elbow, 45 degree elbow produces less friction, and with the lower pressure.

45 degree elbow of short radius

SR Elbow in 45 degree is usually attached to copper, plastic, steel, cast iron and lead, and can also be connected to stainless and rubber fixtures. It is widely used in chemical, food, water supply facilities, electronic industry, chemical pipelines, horticulture, agriculture production, solar equipment pipelines, air conditioning pipeline and other fields.

Stainless Steel Elbow Material

There are various stainless steels to be adapted for pipe elbow used in different applications, as we know that stainless steel exhibits excellent properties to resist corrosion, heating and high pressure, thus, stainless steel elbow is often used in critical applications.

304 and 316L are the most used stainless steel grades, they are both high chromium austenitic grades and can be met the most cases, and other grades are available, such as 321/321H and 347/347H. Some special alloys are usually for the elbow as well, like 904L, and 2205.
