Buy & Import Orifice Flange Assembly from Asp Instrumentation - Wholesale Supply

The Orifice Flange Assembly from Asp Instrumentation integrates a flange with machined pressure tapings to host an orifice plate or flow nozzle. It is manufactured from carbon steel ASTM A105N and low‑temperature steel ASTM A350 LF2, both complying with ANSI/ASME standards. Size offerings start at 1 inch nominal bore and extend to 24 inch, with pressure class ratings from Class 300 to 2500 lbs. Each assembly is supplied as a complete unit ready for installation.

In typical practice, ASTM A105N serves standard temperature applications while ASTM A350 LF2 is selected for sub‑ambient environments, providing a reliable match to the operating conditions of upstream oil and gas or refining processes. The assemblies are usually finished mill‑smooth or hot‑dip galvanized, and the bolt pattern follows ASME B16.5 tables. Temperature limits for these steels generally range from - 20 °F to 850 °F, which aligns with most process plant requirements. Such typical specifications help ensure seamless integration with standard orifice plates and transmitters.

Primary users include engineering firms, EPC contractors and plant operators that need precise flow metering for custody transfer or process optimisation. Prospective buyers should request mill‑test certificates, confirm the pressure class and size, and discuss any special surface‑treatment requirements. Details of MOQ, lead‑time and Incoterms are not disclosed in the listing and must be clarified with Asp Instrumentation before finalising a contract.

Asp Instrumentation supplies the assembly in carbon steel ASTM A105N and low‑temperature steel ASTM A350 LF2. Request the mill‑test report to verify the exact grade for your application.

Sourcing Orifice Flange Assembly from Asp Instrumentation - India Import Guide

Before committing to a purchase, obtain the mill‑test report, material grade certification and confirmation of the pressure class. Verify the supplier’s registered address and request any third‑party inspection reports that may be available. Clear documentation of these items reduces the risk of receiving non‑conforming assemblies.

Logistics for Indian‑origin flange assemblies typically involve sea freight from ports such as Mundra or Nhava Sheva. Discuss Incoterms, expected lead‑time and preferred payment method directly with Asp Instrumentation, as these details are not disclosed in the listing. Agreeing on these terms early helps avoid unexpected delays or cost adjustments.

Arrange a pre‑shipment inspection by an accredited agency to check dimensions, material markings and surface finish. Upon arrival, request a certificate of conformity and any required customs documentation. Maintaining records of inspection results and certificates supports downstream quality assurance and regulatory compliance.
