Raised Face-manufacture,factory,supplier from China

Face finish: The finish on the face of flange is measured as an Arithmetical Average Roughness Height(AARH). The finish is determined by the standard used. For example, ANSI B16.5 specifies face finishes within a range 125AARH-500AARH(3.2Ra to 12.5Ra). Other finishes are available on requst, for example 1.6 Ra max,1.6/3.2 Ra, 3.2/6.3Ra or 6.3/12.5Ra. The range 3.2/6.3Ra is most common.Product Specification: 1. Standard:ASME B16.5; ASME B 16.47 Series A(MSS SP-44); ASME B 16.47 Series BAWWA C2072.

A flanged joint is composed of separate and independent, although interrelated components: the flanges, gasket, and bolting, which are assembled by another influence, the assembler. Proper controls must be exercised in the selection and application for all these elements to attain a joint that has acceptable leak tightness. Special techniques1.

Flange types:Weld NeckThis flange is circumferntially welded into the system at its neck which means that the integrity of the butt welded area can be easily examined by radiography. The bores of both pipe and flange match, which reduces turbulence and erosion inside the pipeline. The weld neck is therefore favoured in critical applications.Slip OnThis flange is slipped over the pipe and then fillet welded. Slip-on flanges are easy to use in fabricated applications.BlindThis flange is used to blank off pipelines, valves and pumps, it can also be used as an inspection cover.

Flanges Introduction:A flange is a approach of connecting pipes, valves, pumps and other gear to form a pipework system. It additionally provides handy access for cleaning, inspection or modification. Flanges are typically welded or crewed into such systems and then joined with bolts.Product Specification:1.

flange connections, which are used for two kinds of pipes, fittings, or devices, are first fixed in a flange flange, and between the two flanges, flange pads are bolted together, which completes the connection. Some pipe fittings and equipment have their own flange, also belong to the flange connection. Flange connection is an important connection mode in pipeline construction. Flange connection is easy to use and can withstand greater pressure. Flange connection is widely used in industrial pipeline. In the home, the pipe diameter is small, and is low pressure, not visible flange connection.
