The provided source material details specifications for black iron reducing elbows, a type of pipe fitting used in various industrial and construction applications. The information comes from product pages and manufacturer data sheets, focusing on technical standards, material properties, and available sizes. This article summarises the key facts from the source data, presenting them in a clear format for professionals and enthusiasts in the UK seeking to understand these components.
Product Overview and Standards
Black iron reducing elbows are cast fittings designed to connect pipes of different diameters at a 90-degree angle. According to the manufacturer data, these fittings are manufactured from malleable cast iron, conforming to material standards ASTM A-197 and ASTM A47. The production technology is casting, and the fittings are available in three weight types: Light, Medium, and Heavy. This allows for selection based on the required pressure rating and application demands.
The fittings are produced to meet several international and regional standards. Key standards cited include ASME B16.3 and B16.14, as well as BS EN 10242. The manufacturer, LAMAT PIPING, holds certifications including UL/FM, CE, BSI, and ISO 9001, indicating compliance with safety and quality management systems. The pressure ratings are specified as 150LBS, 300LBS, and PN25. For context, PN25 equates to 2.5 Mpa or 363 PSI, which is also classified as Class 150 or 25 Bar. The maximum operating temperature is 200°C (392°F). The hardness is listed as 350MPA with a Brinell hardness of HB150, and the tensile strength is 10%.
Thread Types and Surface Finishes
A critical specification for pipe fittings is the thread type, which ensures compatibility with other system components. The source data indicates that black iron reducing elbows are available with several thread types: BSPT (British Standard Pipe Tapered), NPT (National Pipe Taper), DIN, and ISO. This variety supports use in different regional plumbing and industrial systems.
Surface finishes are also an important consideration, particularly for corrosion resistance and aesthetic purposes. The available finishes include Steam Black, Electrical Zinc Plated, Cold Galvanised, and Hot Dipped Galvanised. These options cater to different environmental conditions and project requirements, from indoor applications to those exposed to moisture or chemicals.
Available Sizes and Configurations
The source data provides extensive lists of specific sizes and configurations for black iron reducing elbows. The size range is broad, from 1/8" up to 6" (DN6 to DN150). The products are listed as "Black Reducing Elbow" or "Black Reducing Street Elbow," with the latter being a specific type of elbow with threads on both ends for a straight-line connection.
From the product listings, a selection of available sizes includes:
- 1/4″ x 1/8″
- 3/8″ x 1/8″
- 3/8″ x 1/4″
- 1/2″ x 1/4″
- 1/2″ x 3/8″
- 3/4″ x 3/8″
- 3/4″ x 1/2″
- 1″ x 1/2″
- 1″ x 3/4″
- 1-1/4″ x 1/2″
- 1-1/4″ x 3/4″
- 1-1/4″ x 1″
- 1-1/2″ x 3/4″
- 1-1/2″ x 1″
- 1-1/2″ x 1-1/4″
- 2″ x 3/4″
- 2″ x 1″
- 2″ x 1-1/4″
- 2″ x 1-1/2″
- 2-1/2″ x 2″
- 3″ x 2-1/2″
This list demonstrates that reducers are available for a wide range of pipe size transitions, from small-scale domestic projects to larger industrial pipework.
Applications and Packaging
The fittings are designed for use in a variety of demanding sectors. The specified applications include Petrochemical & Gas Industry, Chemical processing, Machinery, Electric Power, Ship Building, Construction, Water Works, and the Valve Industry. This indicates their suitability for high-pressure and high-temperature environments as well as general plumbing and structural work.
For distribution, the manufacturer offers several packaging options: Plywood Cases, Plywood Pallets, or Boxes. The brand is identified as LMP (LAMAT PIPING), and the company highlights advantages such as high quality, ready stock, faster delivery, and the ability to provide customised solutions.
