Wall options

SCH 5S, 10S, 40S, 80S and 160. State the pipe schedule and the fitting wall follows it.

▦︎

Thin wall sizes

SCH 5S and 10S fittings to MSS SP-43 share B16.9 lengths; OD at the bevel differs slightly.

↔︎

Small bore

1/8, 1/4 and 3/8 in come as forged socket weld or threaded items, not buttweld.

✎︎

Takeoff tip

Subtract the A, C or H figure from your centreline dimension to get the pipe cut length.

Ni 200 Reducer Welding Guide

Fabricators follow joint advice from our Nickel 200 Pipe Fittings team.

Filler Metal

• ERNi-1 wire for GTAW and GMAW
• ENi-1 electrodes for SMAW
• Titanium in the filler controls porosity

Joint Cleanliness

• Remove oil, grease, paint and crayon marks
• Sulfur and lead cause hot cracking
• Clean 25 mm each side of the bevel

Shielding and Backing Gas

• Pure argon for torch and root purge
• Avoid nitrogen mixes, they cause porosity
• Keep the purge until the root is cool

Heat Input

• No preheat needed
• Stringer beads, low interpass temperature
• Use stainless brushes kept only for nickel

Corrosion Resistance for ASTM B366 UNS N02200 Cap

Chemical plants rely on ASTM B366 UNS N02200 Buttweld Fittings for alkali duty.

✓︎

Caustic Soda

Strong resistance to sodium and potassium hydroxide, from dilute to concentrated and hot.

≈︎

Salts and Seawater

Handles neutral and alkaline salt solutions; avoid stagnant seawater, where pitting can start.

◆︎

Dry Halogens

Suits dry chlorine, hydrogen chloride and fluorine lines at moderately raised temperature.

◈︎

Food and Organic Media

Keeps product colour and taste intact, with good resistance to many organic acids.

▲︎

Sulfur Warning

Sulfur-bearing gases above 315 °C embrittle the metal, so pick another alloy for that duty.

✖︎

Avoid

Nitric acid, ferric chloride, hypochlorite and wet aerated ammonia attack it; choose differently.

Nickel 200 vs Monel 400, Inconel 600, 316L and C276 Pipe Fittings

Grade choice stays simple with a Nickel 200 Pipe Fittings Supplier.

Nickel 200 vs Monel 400

Pick Monel 400 for HF acid and fast seawater; Nickel 200 wins in hot caustic.

Monel 400

Nickel 200 vs Inconel 600

Pick Inconel 600 where the line runs hot or oxidizing beyond Nickel 200 limits.

Inconel 600

Nickel 200 vs 316L

Pick 316L for mild duty and lower cost; it cracks in hot concentrated caustic.

316L

Nickel 200 vs Hastelloy C276

Pick C276 for mixed oxidizing and chloride media, accepting a much higher price.

C276

Nickel 200 vs Nickel 201

Pick Nickel 201 when the design temperature crosses 315 °C for long periods.

Nickel 201

When Nickel 200 is right

Pick it for caustic, dry halogens and product-purity lines below 315 °C.

Werkstoff Nr. 2.4066 Stub End Pressure Rating

Design pressure checks come first for Pure Nickel 200 Buttweld Fittings.

☰︎

Buttweld Rating

ASME B16.9 fittings are rated like seamless pipe of the same material and wall.

▦︎

Forged Classes

ASME B16.11 uses classes 2000, 3000 and 6000 threaded, 3000, 6000 and 9000 socket weld.

◷︎

Temperature Limit

Allowable stress falls as temperature rises; Nickel 200 stays within its 315 °C ceiling.

Alloy 200 Buttweld Fittings vs Alloy 200 Forged Fittings

Forged types ship from this Nickel 200 Pipe Fittings Supplier in Secunderabad.

Buttweld (ASME B16.9)

• Made from B161 pipe or B162 plate
• NPS 1/2 to 48, wall follows the pipe schedule
• Bevelled ends to ASME B16.25
• Class WP-S seamless or WP-W welded
• Full penetration girth weld, no crevice

VS

Forged (ASME B16.11)

• Made from B160 bar or B564 forging stock
• NPS 1/8 to 4, socket weld or threaded
• Socket weld classes 3000, 6000, 9000
• Threaded classes 2000, 3000, 6000
• NPT standard; BSP on request

▲︎

Choose buttweld when

Line size is 2 in and above, the fluid must not sit in a socket gap, or the code asks for radiographed joints.

⚙︎

Choose forged when

Bore is 1 1/2 in or smaller, instrument and drain connections need quick make-up, or pressure class ratings are specified.

✓︎

One PO, both routes

Mixed kits are packed per isometric, each piece tagged with its own heat and class.

Nickel 200 vs Nickel 201 Pipe Fittings

Temperature decides grade, advises this Nickel 200 Pipe Fittings Supplier in Visakhapatnam.

Nickel 200, WPN (N02200)

• Carbon 0.15% max
• Rated for service to 315 °C (600 °F)
• Annealed pipe basis: 380 MPa tensile, 105 MPa yield
• W.Nr. 2.4066, BS NA 11
• Lower cost, larger stock

VS

Nickel 201, WPNL (N02201)

• Carbon 0.02% max
• Preferred above 315 °C
• Annealed pipe basis: 345 MPa tensile, 80 MPa yield
• W.Nr. 2.4068, BS NA 12
• Same B366 spec, same B16.9 sizes

♨︎

Why the 315 °C line

Held for long periods between roughly 425 and 650 °C, the 0.15% carbon in Nickel 200 comes out as graphite and ductility falls.

◈︎

Dual-certified fittings

A heat under 0.02% carbon can be certified WPN and WPNL together; we mark both on the MTC when the melt qualifies.

✓︎

What to write on the PO

Give the design temperature and the pipe grade; the fitting grade is then matched so the weld joint is one chemistry.
