1. What standards are the pipes manufactured to?
Answer:
Our nickel alloy and stainless steel pipes are manufactured according to international standards such as ASTM, ASME, EN, and DIN. Common standards include ASTM B444 (Inconel 625), ASTM B423 (Incoloy 825), ASTM B165 (Monel 400), ASTM B622 (Hastelloy C276/C22), and ASTM A790 (Duplex 2205 / Super Duplex 2507). Certificates can be provided upon request.
2. What are the main applications of these alloys?
Answer:
These materials are widely used in industries requiring high strength and corrosion resistance, including oil & gas, chemical processing, marine engineering, power generation, aerospace, and offshore platforms. For example, Inconel 625 and 718 are suitable for high-temperature and high-pressure environments, while Duplex 2205 and 2507 are commonly used in seawater and chloride-rich applications.
3. What sizes and forms are available?
Answer:
We supply seamless and welded pipes in a wide range of sizes. Typical outer diameters range from 6 mm to 1000 mm, with custom wall thickness and length available. Pipes can be supplied in random length, fixed length, or cut-to-size according to customer requirements.
4. What testing and inspection procedures are performed?
Answer:
All products undergo strict quality control procedures, including chemical composition analysis, mechanical testing (tensile, yield, elongation), hardness testing, ultrasonic testing (UT), hydrostatic testing, and PMI (Positive Material Identification). Third-party inspection (such as SGS, BV, TUV) is available upon request.
5. What surface finishes and additional processing options are available?
Answer:
Pipes can be supplied with pickled & annealed surface, bright annealed finish, or sandblasted surface. Additional services such as cutting, beveling, machining, polishing, and special packaging for export are also available based on customer specifications.
