We supply carbon steel pipe flanges (weld neck, slip-on, blind, threaded, socket weld and lap joint), butt-weld elbows, tees and reducers, plus stainless steel flanges in common grades. Sizes and pressure classes follow ASME B16.5 and B16.9.

There is no strict minimum. Standard items in stock can be mixed in one order, and a small trial order is always welcome so you can check our quality before placing a full order.

Yes. We can prepare sample pieces for your quality check. The samples are free; the courier cost is on your side.

We accept T/T and, for established customers, L/C at sight. Payment terms are confirmed with the quotation before any order is placed.
5. What is your typical lead time?
Lead time depends on size, quantity and surface treatment. We confirm a firm production schedule in the quotation, so you know the delivery date before you order.
6. Which standards do your products follow?
Our main product line follows the ASME / ASTM system, including ASME B16.5, ASME B16.9, ASTM A105 and ASTM A106. Other standards are available on request through our custom service.
