The technology of carbon steel elbow is briefly introduced

Carbon steel elbow technology is the use of a layer of mold to form a definite color.Because the alloy push elbow utilizes an ever-present layer of film, it does not fade and does not require the same maintenance as paint.Color alloy push elbow can also be molding treatment, even in the bend will not have any adverse effect on the color.The process is closely related to the operation time, how much the steel elbow, time different colors will change.The order of color changes is brown, gold, red, purple and green.A major feature of this process is that its final appearance can reflect the original surface of the material.

The process of the carbon steel elbow is to soak the alloy push elbow in a solution tank, steel elbow, solution containing 250 grams of Cr203 per liter, 490 grams of sulfuric acid per liter is also acceptable, the temperature range is 80-85 degrees, soaking time depends on the color required, not more than 25 minutes, the alloy push elbow is used in clean cold water after rinsing,Then it was placed in A liquid of 250 g /1 l chloric acid and 2.5 g /1 l phosphoric acid at room temperature for approximately 10 min with A current density of 0.2-0.4A/dm2.

Seamless elbow manufacturers: elbow material

Elbow materials include cast iron, stainless steel, alloy steel, malleable iron, carbon steel, nonferrous metal and plastic, etc.There are direct welding (commonly used) flange connection, hot melt connection, electric fusion connection, threaded connection and socket connection, etc.According to the production process can be divided into: welding elbow, stamping elbow, push elbow, casting elbow, etc.Other names: 90 degree bend, right Angle bend, love and love bend, etc.

Description: Seamless elbow is a kind of pipe fittings commonly used in plumbing installation. It is used to connect the bend of the pipe and change the direction of the pipe.Other names: 90° elbow, right Angle bend, love bend, stamping elbow, press elbow, machine elbow, welding elbow, etc.
