FAQ Section Thick Walled Stainless Steel Tube to Brazil
1. Why choose 304 stainless steel for thick-walled tubes?
304 stainless offers optimal cost-performance for industrial applications requiring corrosion resistance and strength. Its 8% nickel content ensures durability in humid climates like Brazil’s.
2. Can KCM produce diameters beyond 300 mm?
Yes. Our facilities support heavy-walled stainless steel tubes up to 1020 mm OD with wall thicknesses up to 80 mm.
3. How was the 15-day timeline achieved?
- Pre-negotiated raw material stocks.
- Dedicated non-standard production line.
- Strategic logistics partnerships.
4. What standards compliance?
ASTM A312, EN 10216-5, ASTM A511 and GOST JIS. MTC are available or 3rd Party Inspection is acceptble.
5. Does KCM stock standard-sized thick-walled tubes for urgent orders?
Yes. We maintain inventory for common dimensions (e.g., 219×20mm, 325×25mm) in 304/316L grades. For non-standard sizes like 242×31mm, production can begin within 24 hours after design confirmation. Contact our sales team to check stock availability.
6. What is the minimum order quantity (MOQ) for custom tubes?
KCM accommodates both small-batch prototyping and bulk orders. MOQ starts at 1 tube for non-standard large diameter stainless steel pipes, ideal for R&D or critical repairs.
7. How does KCM ensure precision for heavy-walled tubes?
- CNC-controlled extrusion: Guarantees ± 3mm wall thickness uniformity.
- Laser scanning: Validates OD and straightness (<0.2% deviation).
- Density testing: X-ray diffraction ensures 7.93–8.00 g/cm³ (±1–2%).
8. Can KCM combine custom and standard tubes in one shipment?
Absolutely. We optimize logistics by merging non-standard thick-walled stainless steel tubes with standard inventory items (e.g., flanges, fittings) to reduce costs and lead times.
9. What surface treatments are available?
- Pickling & Passivation: Removes oxide layers and enhances corrosion resistance.
- Polishing: Achieves Ra ≤0.8 μm for sanitary or aesthetic applications.
- Heat Treatment: Stress-relieving for high-pressure environments.
10. How does KCM handle post-delivery quality issues?
We provide a 12-month warranty on material and workmanship. Our team conducts root-cause analysis within 48 hours of notification and offers replacements or refunds if defects are confirmed.
11. Are there restrictions on tube length?
Our mills produce seamless tubes up to 12 meters in length. Longer tubes can be supplied as welded sections (subject to application requirements).
12. Does KCM assist with design optimization?
Yes. Our engineers use FEA (Finite Element Analysis) to recommend cost-effective adjustments, such as reducing wall thickness without compromising strength for heavy-walled stainless steel tubes.
13. What packaging is used for international shipping?
- Wooden crates: For heavy tubes (OD >200mm), with anti-corrosion VCI paper.
- Stretch wrapping: For standard tubes, with edge protectors to prevent dents.
- Custom packaging solutions available for fragile or oversized orders.

Yes. We produce tubes in 316L (marine environments), 321 (high-temperature), Duplex 2205 (high chloride resistance), and super austenitic grades (e.g., 904L).
16. What testing methods validate tube quality?
- Hydrostatic testing: Up to 1.5x working pressure.
- UT (Ultrasonic Testing): Detects internal flaws.
- PMI (Positive Material Identification): Verifies alloy composition.
17. How are pricing and payment terms structured?
- Small orders: Full payment upfront.
- Bulk orders: 30% deposit, 70% before shipment.
- Competitive pricing for thick-walled stainless steel tubes due to in-house billet production.
