DIRECT MANUFACTURING · JIANGYIN, CHINA
NOKX FACTORY
Direct manufacturing support for welded pipes, fittings, flanges, forgings and precision-machined components—from drawing review to inspection and export preparation.
FACTORY AT A GLANCE
Two Manufacturing Sites. One Coordinated Route.
NOKX began with stainless welded-pipe manufacturing in 2015. The production scope expanded to seamless pipes and pipe fittings in 2020, followed by a new forging and CNC machining site in 2024 and additional non-destructive testing resources in 2026.
Both Jiangyin sites operate under the same ownership and manufacturing coordination. The Meiyuan Street site focuses on welded pipes, seamless pipes and fittings; the Qingyang Town site supports hot-die forging, open-die forging, CNC machining and radiographic inspection.

MANUFACTURING CAPABILITIES
One Coordinated Manufacturing Route
Product geometry, material grade, standard, dimensions and inspection scope are reviewed against each enquiry before a manufacturing route is confirmed.
Welded Pipes
Stainless, duplex, nickel-alloy and selected carbon or alloy steel welded pipes. The submitted manufacturing range is OD 108–2000 mm with 5–200 mm wall thickness, subject to drawing, material and standard review.
- Representative grades: 1.4301 / TP304, 1.4404 / TP316L and 1.4462 / 2205
- Standard systems: ASTM / ASME, EN, GB/T, JIS and KS
Pipe Fittings
Elbows, tees, reducers and caps coordinated with the pipe specification. Manufacturing routes can include forming, push-forming, welded fabrication, heat treatment and final inspection.
- Materials coordinated with the welded-pipe range
- Dimensions and wall thickness reviewed per drawing or standard
Flanges & Tube Sheets
Standard and custom forged flanges, weld-neck configurations, flange blanks and tube sheets supported from forging through machining and inspection.
- ASME, EN, GB/T, JIS and KS systems reviewed
- Pressure class and final geometry confirmed from the project specification
Hot / Open-Die Forgings
Crankshafts, lifting lugs, rings, discs, shafts, flange blanks and drawing-based components.
- 6000-ton hot-die forging press with 1.8 × 1.8 m working table
- 13000-ton friction screw press and 1000-ton open-die forging hammer
CNC Machined Components
Automotive and industrial parts manufactured from approved drawings using machining centres and coordinated turning, milling, drilling and boring operations.
- Stainless, carbon and alloy steels reviewed by project
- Final tolerance and machining envelope confirmed after drawing review
MANUFACTURING FLOW
From Requirement to Delivery
Each project follows a coordinated route defined by product type, drawing and acceptance requirements.

FACTORY FAQ
Questions Before You Send a Drawing
Practical information for international buyers, engineers and project procurement teams.
Is NOKX a direct manufacturer?
Yes. NOKX is the unified sales brand for two Jiangyin manufacturing sites under the same ownership. The Meiyuan Street site focuses on pipes and fittings, while the Qingyang Town site supports forging, CNC machining and radiographic inspection.
What products are manufactured by NOKX?
The current scope includes welded pipes, seamless pipes, pipe fittings, flanges and tube sheets, hot-die and open-die forgings, and CNC machined components.
Can NOKX manufacture from customer drawings?
Yes. Drawings, materials, standards, quantities and inspection requirements are reviewed before a manufacturing route is confirmed.
Which materials and standards are supported?
Representative materials include austenitic and duplex stainless steels, nickel alloys and selected carbon or alloy steels. ASTM/ASME, EN, GB/T, JIS and KS requirements can be reviewed against the specific product and drawing.
What inspection documents can be supplied?
Depending on the agreed inspection plan, documentation can include material certificates, dimensional reports, NDT records, mechanical test reports and packing documents.
Can customers arrange a factory visit?
