AstroForge Fitting Industries

ASME B16.47 / ANSI / ASME B16.5 Slip On Flange Manufacturer

Astroforge Fitting Industries are Manufacturers, Suppliers, and Exporters of Slip-on Flanges in India. We are Manufacturing high-quality Slip-on Flanges which are suitable for low-pressure applications. Our qualitative range of Slip-on Flanges is exclusively designed for several piping applications of varied industries. Slip-on Flanges that are precision engineered using the simplest quality material. We also customize these industrial flanges as per the necessities of the clients.

Slip-on Flanges are typically given a raised or flat face. When a raised face is important for slip-on pipe flanges, the quality height is 1/16″ for slip-on pipe flanges under 400#. For slip-on pipe flanges of 400# and up, the quality slip-on-pipe flange raised face height is 1/4″. Slip-on Flange is actually a ring that’s placed over the pipe end, with the flange face extending from the top of the pipe by enough distance to use a weld bead on the within diameter.

Slip-on Pipe Flanges altogether steel material grades, including carbon slip-on pipe flanges, chrome steel slip-on pipe flanges, and alloy slip-on pipe flanges. We even have many various slip-on pipe flanges available and ready to ship. Slip-on pipe flanges available include AWWA slip-on pipe flanges, ANSI Slip-on Pipe Flanges, Pressure Vessel slip pipe flanges, and slip-on pipe flanges that match the OD and drilling of ASME flanges. The slip-on flange can also be used joint flanges if type b or Type C stub ends are used.

ASME B16.47 / ANSI B16.5 Slip On Flanges Application Industries

ASME B16.47 / ANSI B16.5 Slip On Flanges Inspection

Our qualified inspection engineer performed inspection on Slip On Flanges based on reference standards of ASME B31.1, B31.3, B16.5, ASME II , V , VIII , IX , DIN, AS/NZ standards etc. A visual test performed to identify surface porosity, cracks, and open structure defects. A dimensional inspection performed to confirm that the different types of flange, in this case its Slip on Flange, Raised Face Slip on Flange, Flat Face Slip on Flange, etc. are manufactured according to the ASME Specification, that specifies the dimensions and indicates the design tolerances. A tensile test is conducted to test the yield strength, the tensile strength, and the elongation restrictions. A hardness test is conducted to check micro-hardness and surface hardness to confirm the acid environment performance and material performance. Magnetic particle inspection is performed to detect locating surface and near subsurface discontinuities in ferromagnetic materials, if some surface cracks, folds, thrust fault, pit or gas hole.

ANSI B16.5 Slip On Flanges Packing & Forwarding

We follow the packing procedure of Slip On Flanges to insure damage free delivery of BS10 Slip On Flange to our valuable customers in India and overseas. usually the packing way include wooden pallet, wooden box, iron & steel pallet, iron & steel cage etc. Because of the normal wooden pallets or wooden boxes have to do fumigation treatment, we choose plywood box or case or plywood pallet to pack Series A and Series B Slip On Flange without fumigation treatment. Whatever plywood or iron & steel packing way, we make sure that it must be strong, seaworthy, waterproof. All details of ASME B16.5 Slip On Flange are also stick with flanges packing so that it can be easy to understand and we insure that packing can ease the process of loading and unloading of goods.
