Frequently Asked Questions
The class number refers to the pressure rating. Class 3000 is designed for medium-to-high pressure applications, while Class 6000 is for extreme high-pressure environments. The wall thickness and material density increase as the class number rises.
Yes, we offer these unions in various stainless steel grades (such as 304 and 316) specifically to prevent galvanic corrosion and ensure compatibility with stainless steel systems.
Yes, our manufacturing facility can produce both National Pipe Thread (NPT) for North American markets and British Standard Pipe Taper (BSPT) for international standards.
Forging compresses the metal grain structure, eliminating internal voids and gas pockets common in casting. This results in significantly higher tensile strength and better resistance to pressure spikes.
Our products are supplied with Mill Test Certificates (MTC) according to EN 10204 3.1, confirming chemical composition and mechanical properties.
While highly durable, we recommend annual visual inspections and pressure testing every 2-3 years, depending on the corrosivity of the medium being transported.
