Inner Diameter 2000mm Stainless Steel Ellipsoidal Head For Water Treatment Filtration Equipment
Brand Overview
Henan Guojiang Precision Formed Head is a leading domestic manufacturer of precision pressure vessel components, with over 12 years of expertise in R&D, production, and customisation of heads. Our products are distributed in more than 10 countries and regions worldwide, focusing on meeting the high standards for reliability and precision in water treatment and other industries, and are trusted by customers at home and abroad.
Product Features
Structural Reliability: The combination of 2000mm inner diameter and 12mm thickness with cold-formed elliptical design ensures uniform stress distribution under pressure, reducing the risk of deformation and leakage, and guaranteeing long-term stable operation of water treatment equipment
Corrosion Resistance & Cleanliness: Stainless steel material with surface roughness Ra ≤ 0.8μm resists corrosion from water treatment media, avoids secondary pollution, and meets the cleanliness standards of the water treatment industry
Cost-Efficiency: Optimised thickness and material selection balance performance and procurement costs, and the durable design reduces long-term maintenance expenses
Global Compatibility: Compliant with multiple international standards and certifications, enabling seamless integration into the global water treatment equipment supply chain
Forming Technology: Cold Forming
The cold forming process is suitable for the characteristics of the stainless steel material of this model, avoiding thermal deformation and fully retaining the original mechanical properties of the material (such as ductility and weldability). The company is equipped with 6,000-ton hydraulic presses to ensure uniform forming of the elliptical structure, strictly following the 2:1 major-to-minor axis ratio specified in GB/T 25198 and ASME standards to ensure balanced stress distribution under pressure.
Quality Assurance
Inspection Protocols: 100% full coverage inspection for key performance indicators, including ultrasonic testing (UT) for internal defects, penetrant testing (PT) for surface flaws, and dimensional accuracy verification using 3D laser scanners.
Applicable Standards: Compliant with GB/T 25198-2023 (China), ASME BPVC Sec.VIII Div 1 (North America), and PED 2014/68/EU (Europe), ensuring global market access.
Certifications: ISO 9001:2015 Quality Management System, ISO 14001:2015 Environmental Management System, and ASME "U" Stamp approval.
