Size Range and Custom Manufacturing

 

We provide standard and customized dimensions to satisfy distinct engineering applications across global supply chains.

Outside Diameter: Small precision tubes for instrumentation to large-diameter industrial pipes for fluid distribution.

Wall Thickness: Thin-wall configurations for sanitary systems and heavy-wall configurations for high-pressure infrastructure.

Length: Standard mill lengths or custom cut-to-length production to optimize container loading and minimize on-site waste.


Pipe End Configurations:
Plain End (PE): Square cut and deburred for standard couplings or socket welding.

Beveled End (BE): Precision-machined ends (strictly to ANSI B16.25) to facilitate rapid, high-quality butt welding on site.

Threaded End (TE): Male or female threading (NPT/BSP) for secure mechanical joint systems.

 

Available Stainless Steel Grades

Different working environments require different material properties. We supply pipes manufactured from commonly specified stainless steel grades.

 

GradeTypical CharacteristicsCommon Applications
304Excellent general corrosion resistance and good formabilityFood processing, water systems, construction
304LLower carbon content for improved weldabilityFabrication projects and welded assemblies
316Enhanced resistance to chlorides and marine environmentsChemical plants, offshore facilities
316LLow-carbon version with improved welding performancePharmaceutical and marine applications
310SHigh-temperature oxidation resistanceFurnaces and thermal processing equipment
321Stabilized alloy suitable for elevated temperaturesExhaust systems and heat exchangers
Duplex 2205High strength with superior corrosion resistanceOil and gas, desalination, offshore engineering

 

Quality Control

Reliable industrial piping requires more than visual inspection. Quality verification typically includes multiple checkpoints throughout production.

 

 

Raw Material Verification: 100% inspection and chemical checks on inbound steel billets and strips.

 

Chemical Composition Analysis: Optical Spectrometer and PMI (Positive Material Identification) validation.

 

Dimensional Measurement: Strict monitoring of Outer Diameter, Wall Thickness, straightness, and ovality tolerances.

 

Nondestructive Testing (NDT): 100% Hydrostatic pressure testing and Eddy Current testing to guarantee zero leaks.

 

Advanced Inspections: Ultrasonic testing or X-ray radiography when specified by project engineers.

 

Surface & Weld Inspection: High-resolution surface quality checking along with specialized weld seam visual and automated reviews.

 

Nondestructive Testing (NDT): 100% Hydrostatic pressure testing and Eddy Current testing to guarantee zero leaks.

 

Support for Custom Projects

 

Many industrial projects require specifications beyond standard catalogs.

We support customized manufacturing for:

Special outside diameters and custom wall thicknesses (heavy wall parameters)

Project-specific tolerances, fixed lengths, and special stainless steel grades

Targeted surface treatment requirements (specific grit polishing or targeted pickling)

Continuous OEM marking, customized packaging, and project-specific labeling

FAQ

 

 

Q: What is the difference between seamless and welded stainless steel pipe?

A: Seamless pipes are manufactured without a weld seam and are commonly used in high-pressure or high-temperature applications. Welded pipes are made from stainless steel strip or plate and offer a cost-effective solution for general industrial and structural use.

Q: Which grade is better, 304 or 316 stainless steel pipe?

A: Grade 304 is suitable for most general-purpose applications and provides excellent corrosion resistance. Grade 316 offers better resistance to chlorides and chemicals, making it ideal for marine and harsh industrial environments.

Q: Can you manufacture custom sizes?

A: Yes. We can produce custom diameters, wall thicknesses, lengths, and surface finishes based on your drawings or technical requirements.

Q: What standards do your stainless steel pipes comply with?

A: Our products can be manufactured to international standards such as ASTM, ASME, EN, DIN, and JIS, depending on your project requirements.

Q: Do you provide Mill Test Certificates (MTC)?

A: Yes. Mill Test Certificates (MTC) are available upon request and include key material and inspection information for traceability.

Q: What is your minimum order quantity?

A: The MOQ depends on the product specification and order type. Please contact us with your requirements for a customized quotation.

Q: Can I request samples before placing a bulk order?

A: Yes. Samples are available for many standard products so you can verify quality and specifications before mass production.

Q: How long is your production lead time?

A: Lead time varies by order size and product specifications. Standard orders are usually completed faster than customized projects.

Q: What surface finishes are available?

A: We offer No.1, 2B, BA, pickled, brushed, and mirror polished finishes to suit different industrial and decorative applications.

Q: How do you ensure product quality before shipment?

A: Every order undergoes material verification, dimensional inspection, and final quality checks before shipment. Testing reports and certificates can also be provided when required.
