We, Indooverseas put into assets, advances and a workforce that is best, we are producers, providers and exporters of Raised Face Flanges that serve the sustenance handling, nourishment and drink and FMGC industry. A Stainless Steel Raised Face (RF) Flange is the most oftentimes utilized spine write in process plant applications. Monel RF ribs are effortlessly recognized, as the gasket surface of the rib is raised over the blasting circle confront. Accordingly, they are called ‘raised’ face spines. The basic role of a Carbon Steel RF spine is to distillate more weight on a littler gasket zone; along these lines increment the weight regulation ability of the joint. ANSI B16.5 Hastelloy Raised Face Flanges empower the utilization of a scope of gasket outlines like level ring sheet compose, winding injury and twofold jacketed.
Our manufacturing process is highly sophisticated and is divided into various departments supervised by experienced industry experts. We use only quality raw materials that are procured from only established and reliable vendors. We have adopted rigorous quality control practices and procedures to ensure the production of only quality products matching industry standards and parameters.

Requirements are valid for normal situation, in special you have to contact us to introduce.
Our machining and assembly operations have a complete line of metal removal equipment including turning, boring, milling, drilling, grinding, polishing, welding and have testing equipment to manufacture forged steel fittings and valves. This facility also contains all the necessary equipment to support these operations including work holding and cutting tool needs.
The usual materials of flanges include stainless steel, carbon steel, aluminum and plastic.Beginning with this process,the system controls the quality of all incoming materials as per the raw material test certificate of the material. Mild Steel Flanges ( MS ) are of premium quality that ensures high durability, strength and resistivity to varied non-supporting conditions. Also, checking in each size for chemical and physical properties of these materials at Government approved laboratory.
Dimensions from carbon steel and stainless steel flanges are defined in the ASME B16.5 standard. The material qualities for these flanges are defined in the ASTM standards.
The normal rust prevention treatment for steel flanges include yellow (Golden) paint Coating, black paint coating or black phosphating treatment, varnish paint coating, varnish antirust oil coating, electro galvanizing coating (Cold), hot dip galvanizing coating etc.
Steel flanges must be packed with seaworthy packing method then delivery to customers, usually the packing way include wooden box, wooden pallet, iron & steel cage, iron & steel pallet etc. Because of the normal wooden boxes or wooden pallets have to do fumigation treatment, we usually use plywood pallet or plywood case or box to pack steel flanges without fumigation treatment. Whatever plywood or iron & steel packing way, they must be seaworthy, strong, waterproof and easy for loading and unloading.
Shipping mark stick to outside of package. Following shall be marked on flange body
- Manufacturer logo
- ASTM material code
- Material Grade
- Service rating (Pressure-temperature Class))
- Thickness (Schedule)
- Heat No
- Special marking if any QT (Quenched and tempered) or W (Repair by welding)
The final process of dispatch is the most tedious of all , and heavy duty cranes are used for it. With the help of our extensive delivery chain we can ensure time critical deliveries at the behest of our esteemed clients. We are indeed privileged to be able to serve and live upto their expectations and occupy unparalleled postion of Flange makers in China.
