ASTM A234 WP5 WP9 WP11 Alloy Steel Pipe Fittings

Description

Alloy elbow is a general term for a variety of elbows. It is used to connect the two pipes with the same nominal diameter to make the pipe turn at 90 ° or other angles. Alloy elbow materials are various and widely used.

The common bronze alloy elbow is common in the general water pipe, but with the improvement of living standard, many water pipes use stainless steel elbow.

The alloy elbow made of manganese steel is usually used in concrete pipeline, mud pipeline and other pipelines with serious wear consumption because of its excellent performance of bearing impact, extrusion and material wear.

The high manganese steel alloy elbow is used in the pipeline with intense fluid flow and strong impact. The nickel steel alloy elbow is usually used in the normal temperature pipeline with high concentration of oxidizing acid (nitric acid, sulfuric acid). 

Specification

1. ASTM a234 Wp1 wp5 wp9 wp11 wp22 A420 wpl6 wpl3 a860 whpy42 / 52 / 60 / 65 / 70 / 80 / 100 by material.

2. It can be divided into pushing, pressing, forging, casting, etc.

3. Manufacturing standards can be divided into national standards, electricity standards, water standards, American standards, German standards, Japanese standards, Russian standards, etc.

4. According to its curvature radius, it can be divided into long radius elbow and short radius elbow. Long radius elbow refers to the outer diameter of the pipe whose radius of curvature is equal to 1.5 times, that is, r = 1.5D.

5. Short radius elbow means that its radius of curvature is equal to the outer diameter of the pipe, that is, r = 1.0D.

Characteristic

1.  The metal compressed at the inner arc flows and compensates to other parts thinned due to the expanding, so as to obtain the elbow with uniform wall thickness.

2.  Hot push forming has the characteristics of beautiful appearance, uniform wall thickness and continuous operation, which is suitable for mass production.

3.  Therefore, it has become the main forming method of carbon steel and alloy steel elbow, and it is also used in the forming of some specifications of stainless steel elbow.

4.  Stamping elbow is the first forming process used in the mass production of seamless elbow.

5.  It has been replaced by hot pushing or other forming processes in the production of common elbow specifications.

6.  However, it is still used in some elbow specifications due to the special requirements such as small production quantity, too thick or too thin wall thickness.

7.  The tube blank equal to the outer diameter of the elbow is used for the stamping of the elbow, and the press is used to directly press the elbow in the die.

8.  Compared with the hot push process, the appearance quality of the stamping process is not as good as the former; the outer arc of the stamping elbow is in the drawing state during the forming. 

9.  And there is no extra metal in other parts to compensate, so the wall thickness at the outer arc is about 10% thinner.

10  However, due to the characteristics of single piece production and low cost, stamping elbow technology is mostly used in the manufacture of small batch and thick wall elbow.

Avaliable

1.,But it will be severely corroded in the pipeline with reducing acid (hydrochloric acid, dilute sulfuric acid, etc.), unless the concentration of hydrochloric acid is very low.

2, The martensitic alloy elbow has higher high temperature strength, oxidation resistance and water vapor corrosion resistance under 650 ℃,but its weldability is poor. Therefore, it is often used in high temperature water vapor pipeline and water gas pipeline.

3. The manufacturing process of alloy elbow can be divided into hot push forming and stamping forming.

4. The hot push forming process of alloy elbow is a process in which the blank sheathed on the die moves forward under the push of the pusher, and is heated, expanded and bent during the process.

5. The characteristic of hot push forming is to determine the diameter of tube blank according to the law that the volume before and after the plastic deformation of metal materials is constant.

6. The diameter of tube blank is smaller than the diameter of elbow. The deformation process of billet is controlled by the core die.

Application

1,  There are many kinds of alloy elbows, which can be widely used in power powder conveying, ash conveying, desulfurization and flue, mine tailings conveying and washing system.

2,  It can be used in coal washing system, metallurgical blast furnace powder conveying, dust removal, slag flushing, flue and nitrogen ash removal system, ship dredging and sand pumping system.

3,  And also can be used in cement plant ash conveying, kiln mouth, silo and chute system, petroleum, chemical industry, metallurgy and ship Industries.

4,  Such as shipping, papermaking, electric power, pharmacy, water treatment, chemical fiber, urban construction and mechanical equipment.
