Actually, most of the heat in high-pressure lines comes form the socket weld itself—if you’re running a system above 600°F, the forged carbon steel holds up better than cast alternatives, and the Sch80 wall thickness gives you a solid margin for thermal cycling.
The 6000lb rating is what we typically stock for chemicla transfer lines, though the 9000lb option exists for sour gas service (we usually have stock, but confirm lead time—25 to 35 days depending on the batch). That hexagon head code isn’t just for looks, it lets you get a wrench on the union during assembly without marring weld prep.
We’ve shipped these to refineries in the Middle East and petrochemical plants in Houston, and the blasting treatment removes mill scale that would otherwise contaminate your weld pool—something a lot of buyers don’t think to ask about. It’s certified CE/PED/ISO, so if you’re dealing with European pressure equipment directives, this will satisfy the paperwork without extra testing.
What it does is give you a forged, equal-diameter union in medium carbon steel with either oil coating or hot-dip galvanized finish—choose the galvanized if you’re burying the line, but for above-ground hydrocarbon service the oil coating is better. The connection is socket welding, so you’ll need a proper preheat for carbon steel over 0.5” wall; skip that and you risk hydrogen cracking.
Anyway, to order you’ll need to specify the pressure rating (3000lb, 6000lb, or 9000lb), the size—2 inches is our standard, but our company can do OEM or ODM custom sizes—and whether you want the standdard wooden case packaing or something more rugged for sea freight. HS code is 73079200 for customs.
This union is available in Sch80 wall thickness as standard, but we can customize to other schedules if needed. Just let us know your requirements during the order.
Our MOQ typically starts at 100 pieces for standard specs, but we can negotiate lower quantities for first-time orders or prototypes. Contact us with your exact needs.
Yes, we supply CE, PED, and ISO certificates with each shipment upon request. Just specify which certification you need when placing the order.
Along with blasting, you can opt for oil coating or hot-dip galvanized finish. These are all available as standard surface options for this socket weld union.
We pack in wooden cases with cartons to ensure safe shipping. Lead time is 25 to 35 days from order confirmation, depending on quantity and customization level.
