Pipe Fittings

I. Comprehensive Product Range to Meet Diverse Working Condition Needs

Our product portfolio is comprehensive, accurately matching the pipeline installation requirements under different working conditions. Core products include:

(I) Full Range of Multiple Materials

• Carbon steel elbows: Made of high-quality carbon steels such as Q235 and 20#, featuring economic cost and reliable mechanical strength. Suitable for transporting neutral media like water, steam, and oil under normal temperature and pressure, serving as the preferred solution for general industrial scenarios.

• Stainless steel elbows: Covering mainstream materials including 304, 316, and 316L, with excellent corrosion resistance, high-temperature resistance, and hygiene performance. Suitable for scenarios with corrosive media or high cleanliness requirements such as chemical industry, food, pharmaceutical, and seawater treatment.

• Alloy steel elbows: Adopting low-alloy high-strength steels like 16Mn and Cr5Mo, with outstanding high-temperature resistance, creep resistance, and wear resistance. Specifically designed for harsh working conditions such as high temperature, high pressure, and high wear in power plant boilers and petroleum cracking units.

• Special material elbows: Customizable products made of copper alloy, titanium alloy, non-metallic materials (PVC, FRP, etc.), adapting to special scenario needs such as refrigeration systems and strong corrosive media (chlor-alkali, seawater desalination).

(II) Multiple Specifications and Full Angles

• Complete angles: Regular 90°, 45°, and 180° (U-type) elbows are supplied in batches. Special angles such as 30°, 60°, and 120° can be customized on demand to meet the steering needs of complex pipeline layouts.

• Size coverage: Nominal Diameter (DN) ranges from DN10 to DN2000, with wall thickness grades covering Sch5 to Sch80. Both long-radius (R=1.5DN) and short-radius (R=1.0DN) elbows are in stock, which can accurately match your pipeline specifications.

• Flexible connections: Providing elbows with various connection methods such as butt welding, socket welding, threading, and flanging, adapting to the installation requirements of different pipeline systems to ensure firm connection and reliable sealing.

(III) Multiple Processes and High Quality

• Hot-pushed elbows: Formed by hot pushing process, with uniform wall thickness and high dimensional accuracy. Suitable for medium and low-pressure general pipeline systems, featuring high mass production efficiency and controllable cost.

• Stamped elbows: Mature technology and cost-effective, suitable for mass supply of small-caliber and low-pressure elbows, meeting the basic needs of conventional working conditions.

• Forged elbows: Dense material and extremely high mechanical strength, specially built for harsh high-temperature and high-pressure working conditions. Suitable for core scenarios such as high-pressure pipelines in petrochemical industry and main steam pipelines in power plants.

• Welded/cast elbows: Capable of producing large-caliber and complex-shaped products, adapting to special equipment layouts or low-pressure corrosive medium scenarios, and supporting customization of special-shaped structures.

II. Strict Quality Control to Build a Solid Line of Defense for Pipeline Safety

We have always regarded product quality as the core competitiveness, establishing a full-process quality control system from raw material incoming to finished product delivery:

• Raw material control: Select high-quality billets from well-known domestic steel mills, and strictly inspect the material composition through spectral analysis, chemical analysis and other methods to eliminate unqualified raw materials from entering the factory.

• Process control: Real-time monitor process parameters (temperature, pressure, speed, etc.) during production, and assign special personnel to inspect key processes to ensure stable forming quality.

• Finished product inspection: Each batch of products must undergo appearance inspection and dimensional accuracy measurement (with calipers, angle rulers, etc.). For high-temperature and high-pressure products, additional non-destructive testing such as Radiographic Testing (RT) and Ultrasonic Testing (UT), as well as hydrostatic/pneumatic testing, are performed to ensure no cracks, leaks, or other defects.

• Standard compliance: The entire product series strictly complies with national standards such as GB/T 12459 and GB/T 13401, and can also be produced in accordance with international standards such as ASME B16.9 and EN 10253-2, ensuring compatibility and interchangeability with various domestic and foreign pipeline systems.

III. Customized Solutions to Accurately Match Exclusive Needs

In response to your potential special working conditions and non-standard specification requirements, our company has professional customized service capabilities:

• Working condition-adapted customization: Based on medium characteristics (corrosiveness, temperature, pressure), flow rate requirements, etc., recommend the optimal material, wall thickness, and structural elbow solution for you, avoiding problems of"over-engineering"or"material mismatch".

• Specification and size customization: Support customization of products with non-standard nominal diameter, angle, bending radius, and wall thickness, adapting to space-constrained or special-shaped demand scenarios such as internal pipelines of equipment and special layouts.

• Special process customization: Adopt special manufacturing processes (such as high-precision cold pushing, high-temperature forging) according to requirements, and customize detailed structures such as bevels and flange sealing surfaces to ensure installation adaptability.

IV. Full-Cycle Service Support for Worry-Free Cooperation

We not only provide high-quality products but also strive to offer full-cycle professional services for you:

• Pre-sales consultation: A professional technical team answers your questions about product selection, working condition adaptation, and standard compliance, helping you determine the optimal procurement plan.

• In-sales support: Provide complete documents such as product quality inspection reports and certificates of conformity, and offer on-site installation guidance if needed to ensure correct installation and stable operation of products.

• After-sales guarantee: In case of quality problems within the product warranty period, we will respond immediately and provide solutions such as return, replacement, or repair. Meanwhile, we offer long-term product maintenance consultation services to support the long-term operation of your pipeline system.

Over the years, relying on stable product quality, rich product range, professional customization capabilities, and attentive services, our company has won the trust and long-term cooperation of numerous industrial customers. We look forward to cooperating with you to provide more reliable and suitable pipe elbow solutions for your pipeline system!
