How does the size of alloy steel elbow affect their price?

Larger sized alloy steel elbows cost more because:

  • They require more raw materials.
  • The manufacturing process is more complex and thus, they may be more challenging to produce.
  • They are heavier which leads to higher shipping prices.

How do you ensure the quality of alloy steel fittings during manufacturing?

To ensure quality, alloy steel fittings manufacturer in India suggests the following:

  • Thoroughly inspect the raw materials to verify their chemical composition, mechanical properties, etc.
  • Implement strict process control measures at every stage of manufacturing.
  • Conduct regular inspections to detect any defects.
  • Use precise measurement tools to verify the dimensions and tolerances.

What is the maximum pressure rating for chrome moly fittings based on the schedule?

Higher the schedule for chrome moly fittings, the greater their pressure rating. To determine the exact pressure rating, you can refer to the relevant industry standards.


What are the different coatings that can be applied to alloy steel weld fittings?

  • Zinc coatings protect the chromoly weld fitting from corrosion.
  • Fusion Bonded Epoxy coatings are applied through a fusion process and provide excellent adhesion and resistance to corrosion, chemicals and abrasion.
  • Polyethylene coatings protect against corrosion and are used in underground or submerged applications.
  • PP coatings provide resistance to corrosion, chemicals and high temperatures.
  • PTFE coatings have non stick properties and they can resist alloy steel weld fittings from chemicals and high temperatures.
  • Polyester coatings provide protection against corrosion and offer various color options for aesthetic purposes.

Can you explain the various methods used for joining alloy steel seamless fittings to pipes?

The alloy steel seamless fitting can be joined using buttweld and socket welding. Threaded and flanged connections can also be used for seamless AS fittings. Compression fittings use a ferrule to compress and create a seal between the fitting and the pipe.


Under which pressure can I use alloy steel forged fittings?

The pressure at which you can safely use alloy steel forged fittings depends on its specific type and pressure rating. It also depends on the temperature of the operating environment. The forged alloy steel fitting are available in different pressure classes ranging from 2000# to 9000#.

To determine the appropriate pressure rating, consider a few factors. This includes the type of fitting, its size, material grade, the temperature of the fluid being transported, and the design standards followed by the manufacturer.
