Blind Pipe Flange is used whenever a line must be capped of at a flange. It is good practice to install blind pipe flange at the end of header or at location where future tie-ins are anticipated.
Blind pipe flanges are also used extensively for manways, in which case a davit is recommended for ease in handling the unbolted manway cover.
Blind pipe flange is specified by ANSI B16.47.
Mingda offers blind pipe flange in A105, A105N, SS316, SS304, A20, High Yield & Nickel Alloys.
A pipe flange connects piping and components in a piping system by use of bolted connections and gaskets.
Most commonly used flanges are weld neck flange, slip on flange, blind flange, socket weld flange, threaded flange and lap joint flange (RTJ Flange). This type of connection in a pipe flange allows for ease of disassembly and separation for repair and regular maintenance. Most common specification for carbon steel and stainless steel flange is ANSI B16.5 / ASME B16.5.
Metal flanges are commonly used for industrial, commercial, and institutional application. Steel pipe flanges are available in variety of styles and pressure classes. Metal flanges are classified from 150 to 2500 # rating. In addition to specifying pressure class, certain flanges such as weld neck flange & socket weld flange also require specifying the pipe schedule. This ensures the pipe bore will match the bore of the weld neck or socket weld flange.
Mingda offers wide variety of pipe flanges in carbon steel, stainless steel and nickel alloy. We can also provide special flanges such as long weld neck flange, special material request and high-yield pipe flanges.
