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.

Raw Materials

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.

Flange materials according to ASTM

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 Rust Prevention for Steel Flanges

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.

The Packing Works for Steel Flanges

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.

Marking on the flange

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))
  • Size
  • Thickness (Schedule)
  • Heat No
  • Special marking if any QT (Quenched and tempered) or W (Repair by welding)

Dispatch

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.
