Small size elbow

We supply a full range of Small size elbow schedules ranging from SCH 5 thru Double Extra Heavy, we deliver Small size elbow with Exceptional sizes & Quality.


When the two ends differ in size, the fitting is called a reducing elbow or reducer elbow.

Normally long radius elbows are used in piping as pressure loss is less as compared to short radius elbow. It required more space than short radius elbow.

Small size elbow is curved connecting pieces that join straight lengths of pipe, commonly at a 90° or 45° angle, allowing obstructions to be avoided in plumbing, ventilation, welding, and automotive applications.

 

Sunny Steel is the most acclaimed manufacturer, exporter, distributor and supplier of industrial Small size elbow with required test certificates. You can also Order small quantities, we will be happy to quote best price for small and large quantities & can typically deliver the Small size elbow in minimum time frame anywhere around the globe.

Small size elbow is used to be installed between two lengths of pipe or tube allowing a change of direction, usually these carbon steel elbows distinguished by connection ends. The ends may be machined for butt welding , threaded , or socketed , so the carbon steel elbows are consist of butt weld, thread elbow socket elbow and other series. The material is selected according to the application use such as high temperature use, sanitary fitting, regular industrial use etc.



A324 WP elbow is the manufacturing process of ASTM A234 WPB.

  • W = WELDABLE / wrought
  • P = RELATED TO P NUMBER OF ALLOY MATERIAL

Process

Killed steel, with forgings, bars, plates, sheet, and seamless or fusion-welded tubular products with filler metal added. Forging or shaping operations performed by hammering, pressing, piercing, extruding, upsetting, rolling, bending, fusion welding, machining, or by a combination of two or more of these operations.

Heat Treatment

After forming at an elevated temperature, fittings are cooled to a temperature below the critical range under suitable conditions to prevent injurious defects caused by too rapid cooling, but in no case more rapidly than the cooling rate in still air. Heat treatment temperatures specified are metal (part) temperatures. Heat-treated fittings are to be treated according to paragraph 7 in Specification A960/A960M.

ANSI/ASME B16.25 standard specification

ANSI/ASME B16.25 is the standard covers the preparation of butt welding ends of piping components to be joined into a piping system by welding. The standard includes the butt welding ends information of General scope, Welding Bevel designs, Preparation of inside diameter of welding ends and the tolerances involved. ANSI/ASME B16.25, Buttwelding Ends Following are the dimensions of the butt welding pipe ends according to ANSI B16.25. It includes requirements forwelding bevels, for external and internal shaping of heavy-wall components, and for preparation of internal ends (including dimensions and tolerances). Coverage includes preparation for joints with the following: (a) no backing rings (b) split or noncontinuous backing rings (c) solid or continuous backing rings (d) consumable insert rings (e) gas tungsten arc welding (GTAW) of the root pass Details of preparation for any backing ring must be specified when ordering the component.

How to Calculate a Pipe Bend?

Pipe fittings are necessary to join together pipes, or to change the direction of an existing pipe. Pipes and pipe fittings are made of a variety of materials, depending on the fluid or gas being transported. Most pipe fittings tend to be either threaded or able to slip over the pipes they connect. Whether you are using steel pipes of PVC pipes, a chemical solvent is required to create a seal between the pipe and the fittings. Calculate a Pipe Bend Measure the required length of the pipe to be installed, keeping in mind the extra length required where the pipe will be inserted into the fitting. Mark this length on the pipe. How to Calculate a Pipe Bend Whether you are bending pipe for running electrical conduit or a metal project, calculating the bend for the start and end point can be an important factor. While there are different types of pipe benders on the market, they all share a common identification for the operation. Identified on all pipe benders is the size of pipe the unit w

ISO, the International Organization for Standardization

ISO (International Organization for Standardization) is the world’s largest developer of voluntary International Standards. International Standards give state of the art specifications for products, services and good practice, helping to make industry more efficient and effective. Developed through global consensus, they help to break down barriers to international trade. What we do ISO develops International Standards. We were founded in 1947, and since then have published more than 19 000 International Standards covering almost all aspects of technology and business. From food safety to computers, and agriculture to healthcare, ISO International Standards impact all our lives. Story of ISO The ISO story began in 1946 when delegates from 25 countries met at the Institute of Civil Engineers in London and decided to create a new international organization ‘to facilitate the international coordination and unification of industrial standards’. In February 1947 the new orga
