ARAKI TECHNICAL & RESEARCH CO., LTD.Ver. 1.37.2
FLOW ENGINEERING / SINCE 1974
Half a century of flow engineeringTurning ideas into reality
Taking piping possibilities beyond conventional design.
50 years of pipe branching expertise.
We propose materials, geometry, and manufacturing methods before drawings are finalized.
Together, we turn flow, strength, and manufacturability requirements into the right solution.
1974 founded
Diameter range 1/8〜60 inch
Weld points up to one-third
Projects that began with,'Can this be made?'
From unusual sizes to one-off parts, start by telling us your requirements.

Burring Headers
Stainless steel, carbon steel, aluminium, titanium, copper and more. Talk to us about multi-outlet branches from prototype through to production.

Large-Diameter & Slotted Burring
Sizes and shapes that ordinary equipment struggles with, including large vacuum vessels and energy plant.

Metal AM & Special Fittings
For complex shapes that standard fittings cannot cover, we combine special processing with metal 3D printing.
Manufacturing Services
Choose the manufacturing service that best fits your objective.

Burring Forming
Branches are formed directly from the main pipe to reduce welding, improve strength, flow performance, dimensional accuracy, and quality control, and enable more compact units.

Metal AM & Special Fittings
Flow paths that are difficult to achieve with standard parts or welded assemblies are integrated through metal additive manufacturing and special processing. We work through application, flow, strength and post-processing to arrive at a manufacturable form.

Machine Development & Dedicated Equipment
We design and build burring machines and dedicated equipment for each application, and support the whole process — sharing our know-how, establishing machining conditions, and assisting with improvements.
View details and capabilities
Welding & Fabrication
Machined parts through to welding and fabrication, handled in house. We build piping, vessels, frames and ducts to suit each application, at consistent quality.

On-Site Survey & Pipe/Fitting Reconstruction
We measure on site the partial piping, special fittings and headers that plant maintenance requires replacing or repairing. The existing geometry is reverse engineered, then proposed and produced in a manufacturable form.

Jigs & Prototyping
From form and fit checks with polymer 3D printing through to working prototypes combining metal additive manufacturing and machining. Machining jigs and inspection fixtures are also designed and built to suit each application.
View details and capabilitiesEven before drawings are finalized,talk with our engineers.
Our engineers review your idea directly, even at the early 'can this be made?' stage.
-
01
Share requirements
Drawings are not required. Tell us the application, material, size, quantity and the problem you are facing.
-
02
Engineering review
We look beyond whether it can be machined, weighing safety, quality and cost across welding and fabrication too.
-
03
Method and quotation
We explain the recommended method, any prototyping required, the expected lead time and the quotation.
Engineering tomorrow,
one step ahead.
Fifty years spent on pipe branching. From our works in Jike-cho, Yokohama, we have pursued new ways to branch piping — machining, machine development and sharing know-how. Being a small organisation means our engineers work close together on every problem.
