CAMTOP SMLOCK Hub Clamp | API 16A | 1/2"-7-1/16"

Description

CAMTOP SMLOCK Hub Clamp — API 16A Компактный Clamp Разъём

The CAMTOP SMLOCK Hub Clamp is a compact, high-pressure clamp connector designed and manufactured in full compliance with API 16A specification for wellhead and Christmas tree equipment. Engineered for fast make-up and break-out of hub-type connections, the SMLOCK design eliminates the need for heavy hammer unions and provides a leak-tight seal across all standard pressure classes (2,000 / 3,000 / 5,000 / 10,000 / 15,000 PSI).

Manufactured with appropriate forged materials for specific pressure ratings, the CAMTOP SMLOCK Hub Clamp is available in standard A105 carbon steel and AISI 4130 low-alloy steel, with full customisation to other carbon, low-alloy, and stainless-steel grades per customer specification. Sizes cover the full range from 1/2″ to 7-1/16″ NPSO diameter, with all PSL grades (PSL 1 through PSL 4) and CL temperature classes (CL KU, EE, FF, HH, LL, and exotic classes) available.
