and striving for mutual growth with its customers
as a technology partner.

Tokyo Boeki Engineering Ltd. has established a system for solution development,
manufacturing, and strong service optimized for a variety of energy and
chemical products in the fluid loading field of the energy industry.

With a track record of more than half a century since 1955, the company provides loading arms,
swivel joints, cryogenic butterfly valves, and other high-quality products used for fluid loading
at ports which are critical to stable distribution of energy.

Using its outstanding technological capabilities, the company contributes to the
stable distribution of energy in Japan and around the world,
and contributes to society through fair and free competition as well as operating judiciously.
In the transition to next-generation energy, the company will continue to be a manufacturer that grows alongside

Major Products and Services

Marine Loading Arms

We develop and manufacture various kinds of loading arms suitable for tailored applications. Our products are available for tankers of the several-hundred-ton class through the 500-thousand-ton class. The liquid types handled include chemicals such as concentrated sulfuric acid, cryogenic liquid (-162℃) such as LNG, and liquids with a high freezing point such as molten sulfur (120℃) and asphalt (180℃), in addition to oil-related products. Our marine loading arms are also used to transport slurry in which certain solids are mixed with liquid for conveyance.

Cryogenic Butterfly Valves

We provide a secure sealing mechanism for long term and low torque operation by the combination of a double eccentric disc, a sealing mechanism applying sealing techniques used in the swivel joint for LNG service, and a double ball valve on ERS unit.

Swivel Joints

The TEN swivel joint permits 360-degree rotation allowing smooth flow radii for minimum flow restriction and enables the piping to be configured in any direction as required. In particular, the TEN swivel joint specially designed for cryogenic use features safe and reliable liquid loading performance. Widely used for various applications especially in the food and construction industries.

Butterfly Valves

TEN butterfly valves have various series according to the application and are selectable depending on the quality of the material to meet several applications such as high temperature, high pressure and vacuum. Excellent sealing performance, as well as anti-corrosion and long life are realized. Development is underway for TEN butterfly valves that meet the increasing need for up-sizing for systems growing in size, as well as automation.

Absorption Chillers

We design and manufacture clean and energy conserving absorption chillers that use silica gel as an adsorbent. We provide adsorption chiller products that demonstrate stable freezing capability in compliance with various standards so that they can flexibly cope with the requirements that might be imposed depending on the installation atmosphere and application.
