Stair Fitting Elbow Lost Wax Castings

Product Introduction

In piping systems, elbows are pipe fittings that change the direction of the piping. According to the angle, there are three most commonly used ones: 45° and 90°180°, and other abnormal angle elbows such as 60° are also included according to engineering needs. 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 commonly used way) flange connection, hot-melt connection, electric fusion connection, thread connection, socket connection, etc. According to the production process, it can be divided into: welding elbow, stamping elbow, push elbow, casting elbow, butt welding elbow, etc. Other names: 90-degree elbow, right-angle bend, etc.

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

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

Uses: Stair Fitting Elbow Lost Wax Castings are used to connect two pipes with the same or different nominal diameters so that the pipes can make turns of 90°, 45°, 180°, and various degrees.

A bending radius less than or equal to 1.5 times the pipe diameter belongs to the elbow, and greater than 1.5 times the pipe diameter belongs to the elbow.

Application

A pipe fitting is commonly used in pipeline installation to connect two pipes with the same or different nominal diameters to make the pipes turn at a certain angle, and the nominal pressure is 1-1.6Mpa.

Features

1. Since most of the pipe fittings are used for welding, in order to improve the welding quality, the ends are beveled, with a certain angle and a certain edge. This requirement is also relatively strict, such as the thickness of the edge, the angle and the deviation The scope is specified. The surface quality and mechanical properties are basically the same as the pipe. For the convenience of welding, the steel grade of the pipe fittings and the pipes to be connected is the same.

2. All pipe fittings must undergo surface treatment, and the oxide scales on the inner and outer surfaces are sprayed off by shot blasting, and then coated with anti-corrosion paint. This is for export needs, and moreover, in the country, it is also for the convenience of transportation to prevent rust and oxidation and work in this area must be done.

3. Requirements for packaging. For small pipe fittings, such as export, it is necessary to make a wooden box, of about 1 cubic meter. It is stipulated that the number of elbows in this box should not exceed one ton. This standard allows packages, that is, large sets of small, But the total weight generally cannot exceed 1 ton. For large pieces y, they must be packaged individually, such as 24″, they must be packaged individually. In addition, there are packaging marks, which must indicate the size, steel number, batch number, manufacturer’s trademark, etc.
