What is your return policy for defective or non-compliant ASTM A350 LF2 slip on flanges?
Trusted manufacturing practices and stringent quality measures ensure these flanges are defect-free and application-compliant. However, ASTM A350 LF2 slip on flanges can get returned under warranty in case of defects or non-compliance issues. The standard timeline to issue returns in original, unused condition and packaging is 14 to 30 days after delivery.
The company will issue a refund for the ASTM A350 LF2 Cl1 SORF flange. The industry standard for the return policy may not cover shipping costs under refundable charges.
What is the best method to prevent corrosion on an A350 LF2 SORF flange?
These flanges exhibit moderate corrosion resistance, boosted by a protective coating. An A350 LF2 SORF flange can receive anti-rust painting or galvanisation (zinc coating). High-quality, tested components cut corrosion risks.
We recommend routine cleaning and inspection to remove dirt or debris from the surface. Any damage should get promptly resolved with maintenance equipment.
How do I choose SA 350 LF2 slip on flanges thickness?
Manufacturers can produce SA 350 LF2 slip on flanges in application-specific thicknesses. The metric varies by the pressure exerted and the piping diameter.
Customers can select the dimensions by checking the allowable stress and the corrosion allowance. The internal diameter of the gasket also factors in the calculation.

Which industries commonly use A350 Gr LF2 slip on raised face flanges?
Slip-on flanges with raised faces are easy to install with limited accuracy requirements. A350 Gr LF2 slip on raised face flanges operate in oil and gas production and petrochemicals.
Power generation industries use these components for boilers, pressure vessels, nozzles, and valves.
What are the dimensional standards and specifications for ASTM A350 Gr LF2 SORF plate flanges?
These flanges follow dimensional specifications under ASTM A350. They cater to Classes 150, 300, and so on, up to 2500. ASTM A350 Gr LF2 SORF plate flanges or slip-on raised face components get produced in dimensions of 15 NB to 200 NB, i.e., 1/2 to 8 inches.
The specification also mandates notch toughness testing for the flanges.
What is the manufacturing process for an ASTM A350 LF2 Class 1 slip on threaded flange?
The manufacturing process involves melting and forging. An ASTM A350 LF2 Class 1 slip on threaded flange material is produced by melting using an electric furnace, vacuum-induction melting, etc. Forging allows the manufacturer to obtain desired dimensions without introducing surface defects.
SA 350 LF2 Class 1 slip on flat face flanges operate in crucial sectors, making strict quality control essential during production.
Frequently asked questions:
What is the difference between A105 LF2 and A350 LF2 slip on flanges?
Both specifications cater to forged flanges of carbon steel. However, A350 LF2 Cl1 slip on pipe flanges operate at low temperatures. A105 covers products for higher temperatures.
What is the minimum temperature for A350 LF2 slip on pipe flanges?
It stands at -46°C or -50°F for SA 350 Gr LF2 slip on flanges of Class 1. The valuation for Class 2 is 0°F or -18°C.
What is the difference between A350 LF1 and LF2 reducing slip on flanges?
These two differ in impact test temperatures. LF1 flanges need testing at -20°F, unlike -50°F or -0°F for A 350 LF2 reducing slip on flanges.
What is the chemical composition of A350 LF2 cl2 slip on flat face flanges?
These flanges use carbon steel with small amounts of manganese, silicon, and chromium. They may include minor proportions of molybdenum, phosphorous, sulphur, and copper. This material encompasses elements like niobium and vanadium in traces.
