Trusted supplier of seamless steel pipes, finned tubes, nickel alloys, and high-alloy materials for oil & gas, power generation, refineries, offshore drilling, and shipbuilding.
Explore Our ProductsJiangsu Haohua Industry Group Corporation, established in 1995, is one of China's leading suppliers of industrial tubes and pipes for the petroleum, heat exchanger, and machining industries. Approved by the Ministry of National Industry, we operate as a wholly national group with strategic alignment to China Haohua Chemical Group and China Haohua Energy Resource Co., Ltd.
Our group comprises over five subordinate factories across mainland China, including:
With decades of experience, we deliver precision-engineered piping solutions that meet international standards and serve critical applications in power plants, refineries, offshore platforms, and shipbuilding.
Enhanced heat transfer tubes used in heat exchangers, boilers, and HVAC systems. Available in carbon steel, stainless steel, and alloy variants.
High-performance alloys including Inconel, Incoloy, Monel, and Hastelloy for extreme temperature and corrosive environments.
Seamless and welded stainless steel pipes (ASTM A312, A269) for chemical, pharmaceutical, and food processing industries.
Precision bent U-tubes in stainless steel, alloy steel, and copper for shell-and-tube heat exchangers.
ASTM A335, A213 compliant pipes for high-pressure and high-temperature service in power and petrochemical plants.
High-strength, corrosion-resistant duplex stainless steel (e.g., S32750) for offshore and chemical processing.
Lightweight, highly corrosion-resistant titanium tubes for seawater cooling, desalination, and aerospace applications.
High-integrity cast alloy pipes for extreme thermal cycling and mechanical stress environments.
Durable, corrosion-protected carbon steel pipes for structural and low-pressure fluid transport.
ASTM B111 compliant copper and copper alloy tubes for refrigeration, HVAC, and instrumentation systems.
API 5L, API 5CT compliant line pipes and casing for upstream and midstream oil & gas operations.
Precision-machined tubesheets for heat exchangers and pressure vessels in compliance with ASME standards.
Utilizing rotary piercing and cold drawing techniques to produce high-precision seamless pipes with consistent wall thickness and superior mechanical properties.
High-frequency induction (HFI) welding ensures strong, leak-proof seams. Post-weld heat treatment enhances durability and stress resistance.
CNC-controlled bending processes ensure precise radius control and minimal ovality for optimal heat transfer efficiency.
Mechanical finning, extrusion, or welding methods create high-surface-area tubes for enhanced thermal performance.
Annealing, normalizing, and quenching processes optimize microstructure and mechanical behavior for specific service conditions.
Comprehensive inspection including UT, Eddy Current, Hydrostatic, and PMI ensures every product meets stringent quality standards.
