Lap Joint Flange

Steel Blind Flanges | ASME EN GOST Standard | Reliable Pipeline Sealing End Solution

Lap joint flange is a two-piece pipe connection assembly consisting of a flange ring and a stub end. When bolted, the tightening force of the bolts presses against the gasket through the lip of the stub end, thus achieving a seal.

As a professional lap joint flange manufacturer, Pengrun mainly supplies carbon steel lap joint flanges, with steel lap joint flanges available for custom orders. All products meet ASME B16.5 standards and fit standard stub end dimensions.

    FAQs

    What is a lap joint flange?

    A lap flange is a two-piece pipe connection assembly consisting of a flange ring and a stub end. When bolted, the tightening force of the bolts presses against the gasket through the lip of the stub end, thus achieving a seal.

    What is the difference between lap joint and slip on flanges?

    A lap joint flange has a rotatable backing ring, ideal for frequent pipeline disassembly. A slip on flange is a single welded piece, more cost-effective for permanent low-pressure connections.

    Do you accept custom orders?

    Yes. We maintain a certain inventory of standard-sized flanges to ensure the fastest delivery time. We have the complete equipment and can fully accept custom orders.

    What standards do your flanges follow?

    We can meet various international standards such as ASME, ANSI, EN, DIN, JIS, and GOST.

    Can you provide matched stub ends with the flanges?

    Yes. As a professional lap joint flange manufacturer, Hebei Pengrun supply both backing flanges and matched stub ends.
