316L EHA 300*3 Dished Tank Head: Reduce Connector Costs, Smooth Structure Transition

Core Parameters

Model Specification: 316L EHA 300*3 Dished Tank Head (Reduced Opening), featuring high strength and strong corrosion resistance, suitable for small and medium-sized pressure-bearing equipment.
Dimension Details: Standard inner diameter of 300mm, with a customizable reduced opening size ranging from 80mm to 250mm, compatible with small- and medium-sized storage tanks and pressure vessels in chemical, new energy, and other fields.
Thickness Specification: Nominal thickness 3mm, balancing load-bearing optimisation and structural stability, applicable for working pressures of 0.2MPa-12MPa.

Core Advantages

The development of reduced-opening head closures has minimised welding workload for clients in industries such as pressure vessels, reduced costs for components like gaskets, bolts, and flanges, and enabled smooth structural transitions in equipment.
Superior Corrosion Resistance: The dense oxide film on the surface of 316L stainless steel can resist erosion from the atmosphere, acid and alkali media.
Integrated Reduced Opening Design: Eliminates the need for secondary welding of pipe connections, reduces leakage risk, and cuts the cost of connectors such as gaskets, bolts, and flanges.
Stable and Efficient Structure: The elliptical structure evenly distributes internal pressure, enhances overall pressure resistance, and enables smooth transition of equipment structure.
High-Quality Material Guarantee: Raw materials sourced from certified suppliers with complete Material Test Certificates (MTC).

Applications & Certifications

Complies with ISO 9001:2015 Quality Management System, ASME "U" Stamp and PED Module H certification standards.
Widely used in small and medium-sized storage tanks, pressure vessels and other pressure-bearing equipment in chemical, new energy and other fields.
