Did you know?

DN50 is NOT 50 mm pipe diameter.

DN and NPS are nominal pipe sizes, not actual dimensions.

For example:

NPS 2" = DN50

Pipe OD = 60.3 mm

Using the wrong reference can result in ordering the wrong fl**ge.

We created a free DN ↔ NPS conversion table for engineers and buyers:

πŸ”¬ Science Corner: What is Metallographic Analysis β€” and why does every Fulihua fl**ge go through it?
Steel can look perfect on the outside and still have invisible internal defects β€” inconsistent grain size, uneven phase distribution, micro-cracks that only show under pressure.
That's why we don't just test the surface. We go all the way down to the grain level.
Here's how it works in 6 steps:
1️⃣ Grinding β€” Surface prepared through progressively finer abrasive paper
2️⃣ Polishing β€” Mirror-smooth finish achieved on a rotating polishing wheel
3️⃣ Etching β€” Chemical solution reveals the hidden grain boundaries inside the steel
4️⃣ Drying β€” Cold air stops the reaction at exactly the right moment
5️⃣ Microscope β€” Technician examines grain structure at high magnification
6️⃣ Digital Analysis β€” Software documents grain size, phase distribution & structural uniformity
Every result is recorded. Every batch is traceable. Every fl**ge is verified β€” from the inside out.

πŸ”¬ Science Corner: What is a Charpy Impact Test β€” and why does it matter for your pipeline?
A fl**ge might look flawless on the surface, but real-world pipelines face sudden pressure surges, temperature swings, and mechanical shocks every day.
The Charpy Impact Test is the industry-standard method to measure how much energy a metal can absorb before it fractures. Here's how it works:
1️⃣ A notched specimen is cut from the fl**ge material
2️⃣ It's placed on a fixed anvil inside the testing machine
3️⃣ A pendulum is released and strikes the specimen with controlled force
4️⃣ The absorbed energy β€” measured in joules β€” tells us exactly how tough the material is
At Fulihua Pipeline Equipment, we run this test 3 times per specimen and average the results β€” because one data point is never enough when safety is on the line.
Low joules = brittle = fracture risk ⚠️
High joules = tough = safe under pressure βœ…

πŸ”¬ This is what material verification looks like at Fulihua Pipeline Equipment.

Before any fl**ge leaves our factory, every batch goes through PMI β€” Positive Material Identification β€” our in-house chemical composition analysis process:

πŸ”§ Step 1: Grind the surface to expose fresh, unoxidized metal
πŸ’§ Step 2: Cool the sample β€” eliminating heat interference for accurate readings
🧹 Step 3: Wipe clean β€” removing all contamination before testing
πŸ” Step 4: Place onto our spectrometer analyzer
πŸ’» Step 5: Chemical composition displayed instantly β€” Carbon, Chromium, Molybdenum, Nickel, and more β€” all verified against material specification

Why does this matter?

Because when you order A105, F316L, or F22 fl**ges β€” you need to know that's exactly what you're getting. Not a substitution. Not a mislabeled heat.

At Fulihua, material traceability is not optional. It's standard.

βœ… PMI testing on every batch
βœ… Full material certificates provided
βœ… ASME Β· EN Β· GB/HG standards

πŸ”© This is how every Fulihua fl**ge is drilled to perfection.

Watch our CNC drilling process from start to finish:
βš™οΈ Each fl**ge is carefully loaded and clamped onto the CNC machine
πŸ”§ High-speed drilling cuts through hardened steel β€” every hole positioned to exact tolerance
🧹 Once complete, the operator blows away every last metal chip from the surface
πŸ” Each piece is inspected at the machine β€” hole diameter, face finish, and bolt circle all verified on the spot
πŸš› Only then does it move to the next production stage

Quality starts on the shop floor β€” not only in the lab.

This is a tensile test β€” where we stretch a metal specimen to its
breaking point to measure strength, ductility, and toughness.

The fracture moment isn't a failure. It's data that guarantees
every Fulihua fl**ge meets international standards.
