Picking Two C-Series Heads from Five SKUs: A Turkish Workshop's 1/2-Inch to 4-Inch Sanitary Tube Configuration on FXT20
Welding 1/2-inch through 4-inch 316L and 304L stainless sanitary tube on a Turkish workshop floor is rarely a single-head specification. A buyer in Ankara asked for a line-item configuration review across five closed-head SKUs — C5/C10, C40, C80, C120, and C170 — all on the FXT20 power source. The right answer was not five line items. It was a coverage map: pick two heads that overlap in the middle of the buyer's actual OD band, and let the rest wait until a project earns them. The FYID-Feiyide pipe welding machine catalogue is built so two C-series heads on one FXT20 power source cover most sanitary scopes from 6.35 mm through 168 mm OD without a second power-source purchase.
What the C-Series Coverage Map Actually Looks Like
Each closed head spans a specific OD band — overlaps are not accidental
The C5/C10 head covers 1.6–10 mm OD on micro-tubing and instrumentation lines. The C40 head spans 6.35–38.1 mm OD for 1/4-inch through 1.5-inch sanitary work. The C80 head covers 12.7–76.2 mm OD for 1/2-inch through 3-inch. The C120 head reaches 19–114.3 mm OD for 3/4-inch through 4-inch. The C170 head extends 50.8–168 mm OD for 2-inch through 6-inch sanitary tube. Together those five heads cover from instrumentation tubing all the way through 6-inch sanitary process line on a single 220 V single-phase power source.
Why most sanitary workshops only buy two heads
A Turkish workshop quoting a 1/2-inch through 4-inch sanitary scope needs exactly two C-series heads. C40 covers 6.35–38.1 mm; C120 covers 19–114.3 mm. The 19–38.1 mm overlap is where either head produces a qualified weld, which means a recipe drift on one head still has a fallback on the other. Buying C5/C10, C80, and C170 on top of that is a project-driven decision, not a coverage one. The FYID-Feiyide automatic orbital welding machine kit is right-sized this way deliberately.
How the FYID-Feiyide Tube Welder Configuration Was Scoped
Picking the right two heads from five SKUs
For a sanitary line that walks from 1/2-inch (12.7 mm) to 4-inch (114.3 mm), C40 + C120 is the cleaner pair. C40 handles the small-diameter end with 0.5–2.5 mm wall coverage; C120 handles the large-diameter end with 0.5–3.0 mm wall. Both run from the same FXT20 host. The FYID-Feiyide FXT-Series stores 50 recipes addressable from the 10-inch HMI — supervisor-side lock prevents the line welder from silently retuning a qualified WPS during a shift change.
Spec comparison the buyer needed to see, not a configuration list
| Spec | C5 | C10 | C40 | C80 | C120 | C170 |
|---|---|---|---|---|---|---|
| OD range (mm) | 1.6–10 | 6.35–38.1 | 12.7–76.2 | 19–114.3 | 50.8–168 | |
| OD range (inch) | 1/16–3/8 | 1/4–1.5 | 1/2–3 | 3/4–4 | 3–6 | |
| Wall coverage (mm) | 0.3–1.5 | 0.5–2.5 | 0.5–3.0 | 0.5–3.0 | 0.5–3.0 | |
| Head weight (kg) | 1.8 | 3.5 | 5.0 | 6.5 | 8.5 | |
| Sanitary fit | instrumentation | small CIP | 1/2–3 in | 3/4–4 in | 3–6 in |
How a Two-Head Decision Performs on Sanitary 316L
Coverage map versus catalogue line dump
A workshop that buys C40 + C120 and runs both from one FXT20 typically logs reject rates between 1.5% and 2.5% on 1-inch through 4-inch 316L and 304L sanitary tube once recipes are qualified to ASME BPE. The same workshop buying all five heads usually logs the same reject rate — three of the heads sit on a shelf for nine months waiting for a smaller-diameter or larger-diameter project. The FYID-Feiyide stainless steel tube welder pair tracks the work, not the catalogue.
Where the FXT20 power source actually limits the choice
The FXT20 host runs single-phase 220 V at 4.5 kVA, 5–200 A output, 100% duty at 155 A. That power band is sized for 0.5–3.0 mm wall on 316L and 304L stainless and 0.5–4.0 mm wall on smaller-diameter Duplex 2205 transitions. C170 at the top of its 4.0 mm wall coverage approaches the FXT20 duty edge — fine for sanitary work, marginal for any 6-inch industrial pipe at 5 mm wall or above. The FYID-Feiyide automated pipe welding system in the FXT40 Pro build is the answer for heavier wall, not a different C-series head.
Practical Project Considerations for a Turkish Sanitary Workshop
Power, certification, and supply lead time
The FXT20 host plugs directly into a 220 V single-phase shop panel — no three-phase service upgrade required. The FYID-Feiyide food grade orbital welding machine documentation pack covers ASME BPE for pharmaceutical sanitary segments and 3-A 63-03 for dairy and food-contact joints; CE certification is on the host enclosure. Stocked configuration manufactures in 2–4 days; FCA Shanghai is the default Incoterm for Turkish consignees. Air freight into Ankara is the fastest mode; consolidated sea + final-mile truck into Turkey is the configuration most workshops scope on the second pass.
Reference customers and ODM logo customization
ODM logo on the host enclosure is a one-time tooling step set up in the production scheduling window; it does not add per-unit assembly time once the artwork is locked in. Reference customers in the Turkey region are available on request — the documentation pack lists 304L and 316L sanitary line projects already shipped into the EU and Middle East, with EN ISO 14732 operator qualification cross-mapped to the C-series closed heads.
Frequently Asked Questions
Q: Can a single FXT20 drive all five C-series heads on the same project? A: Yes — the FYID-Feiyide C-Series and FXT-Series share a common head interface, and the FXT20 power source is qualified to drive C5/C10, C40, C80, C120, and C170 from the same plug at 5–200 A. The 50-recipe library stores each head's programs supervisor-side.
Q: Why not buy all five heads for full OD coverage? A: Coverage and utilization are different problems. A 1/2-inch to 4-inch sanitary scope is fully covered by C40 + C120 with overlap in the 19–38.1 mm band. The other three heads sit on the shelf unless a separate project needs them. The FYID-Feiyide pipe welding machine kit is right-sized to the work, not the catalogue.
Q: Does the FYID-Feiyide orbital tube welder handle 3 mm wall on 4-inch 316L? A: Yes. The C120 head at 0.5–3.0 mm wall coverage handles 3 mm 316L on 4-inch (114.3 mm) OD at the upper edge of its qualified range, with FXT20 output at 155 A continuous matching the 100% duty band.
Q: How does the FXT20 handle Turkey's 220 V single-phase shop panel without a power upgrade? A: FXT20 at 4.5 kVA single-phase 220 V plugs directly into a standard Turkish shop circuit. No three-phase service is required. The internal closed-loop water circuit cools the C-series head from the host with no external chiller.
Q: What standards does this configuration qualify under? A: ASME IX for procedure qualification, ASME BPE for pharmaceutical sanitary work, 3-A 63-03 for food-contact joints, EN ISO 14732 for operator qualification, AWS D18.1 for sanitary stainless welding, and CE on the host enclosure.
Q: How long is delivery into Ankara, and what is the Incoterm? A: 2–4 days manufacturing plus transit time depending on mode. FCA Shanghai is the default Incoterm; air freight into Ankara is the fastest mode, with consolidated sea + final-mile truck typically the most cost-effective scope.
