08Х17Н14М2 Extruded Round Pipe

As a professional manufacturer in China, Jilaida factory would like to provide you durable 08Х17Н14М2 Extruded Round Pipe, which offers superior pitting corrosion resistance compared to 304-grade stainless steel and is suitable for chloride-containing environments such as seawater desalination, coastal cooling systems, and offshore platforms.

Decoding the GOST Number

08Х17Н14М2 looks like a code, and it is — but a readable one. 08 means the carbon ceiling sits around 0.08%. Х17 signals roughly 17% chromium. Н14 points to approximately 14% nickel. And М2 is the key letter: molybdenum around 2%. That last element is what separates this grade from 08Х18Н10 (the GOST name for 304). Without molybdenum, stainless resists general corrosion in mild environments. With it, the 08Х17Н14М2 extruded round pipe withstands pitting in chloride-bearing waters — the kind that runs through desalination brine lines, coastal cooling circuits, and offshore utility headers from the Persian Gulf to the Strait of Malacca.

What Your Project Calls It

Why the Round Shape Came from Extrusion

Round pipe can be made several ways — welded, drawn, or extruded. When the spec calls for seamless and the wall is thick relative to the bore, extrusion is the most direct route. A heated cylindrical billet is pushed through a die with a mandrel inside, and the pipe forms in one continuous motion. No seam to x-ray. No weld filler to qualify. No heat-affected zone to worry about in service. For the 08Х17Н14М2 extruded round pipe, this means every meter carries the same structural integrity as every other meter — no weak link, no suspect section. Jiangsu Ji Lai Da Nickel-Based Alloy Co., Ltd. maintains a yield rate above 95% on this process, with wall thickness uniformity within ±0.3 mm and inner surface roughness that meets pickled-finish requirements without secondary honing.

Where the Pipe Ends Up

CIS-designed plants in Uzbekistan and Kazakhstan that still reference GOST specifications. New-build desalination units in Abu Dhabi and Jeddah where the purchase order cites ASTM A312 but the design consultant originally sized the line to GOST pipe schedules. Indian refinery expansion projects that need IS-certified material with ASTM-equivalent documentation. Vietnamese and Indonesian chemical plants sourcing from China under the GB/T designation and converting to local standards at inspection.

The 08Х17Н14М2 extruded round pipe also feeds cold-drawing shops in Maharashtra and Tamil Nadu that produce thin-wall instrumentation tubing for domestic and export markets. Jiangsu Ji Lai Da Nickel-Based Alloy Co., Ltd. supplies these workshops with consistent semi-finished hollows — the extrusion quality upstream determines the drawing yield downstream, and our process is built to support that chain.

Placing Your Order

Tell us the designation your project uses — GOST 08Х17Н14М2, ASTM A312 TP316, GB/T 14976 06Cr17Ni12Mo2, IS 6911 04Cr17Ni12Mo2 — and we certify to that standard on the EN 10204 3.1 certificate. No cross-reference guesswork at your end. Factory-direct China manufacturer, FOB / CIF / DDP to Jebel Ali, Hamad Port, Nhava Sheva, Chennai, Tanjung Priok, or Cat Lai. ISO 9001 plus four additional quality certifications. Submit your RFQ with grade, OD, wall thickness, length, and quantity — we return pricing and production schedule within one working day. Jiangsu Ji Lai Da Nickel-Based Alloy Co., Ltd. handles the documentation in the language and standard your inspector expects.

FAQ

Q1: 08Х17Н14М2 vs 10Х17Н13М2Т — what's the difference?

A: The 'Т' in 10Х17Н13М2Т stands for titanium — it's a stabilized grade, roughly equivalent to 316Ti. Titanium prevents sensitization during welding and prolonged high-temperature exposure. 08Х17Н14М2 is the unstabilized standard grade, equivalent to 316. If your design calls for 10Х17Н13М2Т, you need the titanium-stabilized variant, not this one. We produce both.

Q2: Can this pipe handle sour service (NACE MR0175)?

A: 316 in the solution-annealed condition is listed as acceptable for sour service under NACE MR0175 / ISO 15156 for certain conditions — typically moderate H₂S partial pressure and no elemental sulfur. If your project falls under NACE requirements, provide the service conditions and we'll confirm whether 316 qualifies or if you should move to a higher alloy.

Q3: What about 03Х17Н14М2 — is that the L-grade?

A: Yes. 03Х = ~0.03% carbon max, which is 316L (022Cr17Ni12Mo2 under GB/T). The lower carbon prevents intergranular corrosion in the weld heat-affected zone. If you're welding the pipe and can't anneal after, specify the 03 variant. We carry both carbon levels in our production program.

Q4: Do Gulf EPC contractors accept GOST-certified material?

A: For new-build projects in the Gulf, ASTM A312 is the default specification, and that's how we normally certify for those shipments. The GOST designation becomes relevant when the design was originally done to Russian codes — common in Central Asian projects with Gulf-based EPCs. We can issue dual-designation MTCs when the standards overlap, which covers both scenarios.

Q5: Is hydrostatic testing included?

A: Yes, every pipe is hydro-tested to the pressure required by the applicable standard — typically 1.5× the rated working pressure for the wall thickness and grade. Results are recorded on the MTC. Eddy current or ultrasonic testing is available as a supplementary NDE method on request.

Q6: Packing for sea shipment to the Gulf?

A: Bundles in steel straps with timber bearers, ends capped, VCI anti-corrosion wrap, and outer steel sheet if required by the contract. For UAE and Saudi destinations, we follow the handling specs your forwarder provides. Containerized or break-bulk — we pack to match.
