Gasket Packing Q&A No. 20 Torque Management Guidelines

Gasket Packing Q&A No. 20 Torque Management Guidelines

Is there a guideline for torque management when tightening bolts?

It is difficult to implement torque management for all flanges. Please refer to the following for an idea of the force generated by tightening. Guidelines for pulling force Generated force F - An adult pulling with just wrist strength → 50–100 N - An adult pulling with one arm strength → 100–200 N - An adult pulling with upper body strength → 200–400 N

Expandable graphite gasket "D4000"

Expandable graphite gasket "D4000"

It has a heat resistance temperature equivalent to that of asbestos sheets and is also excellent in corrosion resistance!

"D4000" is a gasket material that has a long-standing high performance record in Europe, where non-asbestos materials have been advanced, and can be used over a wide temperature range from high to extremely low temperatures. Expanded graphite is a material obtained by treating high-purity graphite crystals with chemicals and then heat-treating them at high temperatures. By inserting stainless steel plates (SUS316) into the core material, it becomes a gasket with excellent mechanical strength. 【Features】 ■ Excellent heat resistance and chemical resistance ■ Sealing performance and chemical resistance comparable to asbestos joint sheets ■ Excellent corrosion resistance ■ Wide temperature range from high to extremely low temperatures ■ Excellent compressibility *For more details, please download the PDF or feel free to contact us.

Introduction to Processing Equipment: Press Processing Machine

Introduction to Processing Equipment: Press Processing Machine

We have a large number of press machines, including 300t and 100t large presses and high-speed automatic machines, enabling mass production!

We would like to introduce the "press processing machines" that we own. The manufacturing of sheet gaskets using press processing machines and Thomson dies is an efficient processing method that combines high productivity with the ability to accommodate diverse shapes. Especially in mass production, using Thomson dies, which have relatively low mold production costs, makes it possible to reduce the cost per product. Our company owns a number of presses, including large presses of 300t and 100t, as well as high-speed automatic machines, enabling mass production. 【Features】 ■ An efficient processing method that combines high productivity with the ability to accommodate diverse shapes ■ In mass production, using Thomson dies, which have relatively low mold production costs, makes it possible to reduce the cost per product ■ Owned presses: large presses (300t/100t), high-speed automatic machines, etc. *For more details, please download the PDF or feel free to contact us.

What is the difference between O-rings and gaskets/packings?

What is the difference between O-rings and gaskets/packings?

We will also explain the details of each, such as how they are used and their shapes!

O-rings, gaskets, and packing are all types of seals that prevent the leakage of liquids and gases, but they differ in their usage and shape. An O-ring is a ring-shaped seal with a cross-section that is O-shaped, as its name suggests. It utilizes the elasticity of the material to be compressed when fitted into a groove, thereby achieving a sealing effect. When used for motion, it is a type of packing, and when used for fixing, it is a type of gasket. Due to its simple structure, low cost, and high sealing performance in a compact space, it is used in a wide range of fields, including automobiles, hydraulic and pneumatic equipment, and home appliances. *For more detailed information, please refer to the related links. For further inquiries, feel free to contact us.

Case Study on Measures for Leakage Prevention in PVC Piping

Case Study on Measures for Leakage Prevention in PVC Piping

We will introduce "D Packing," which contributes to reducing water leakage risks and improving construction quality!

Are there any issues regarding leak prevention in PVC piping? "When I tried to stop the leak by tightening it strongly, the flange broke." "The tightening is inconsistent among workers, leading to unstable construction quality." "I thought I had tightened it properly, but it's still leaking." Unlike metal, PVC piping cannot be tightened with excessive force. Therefore, a delicate balance is required with standard sheet gaskets to ensure that they "do not leak but also do not break from over-tightening," which always carries the risk of leakage. *For more details, you can view the related links. Please feel free to contact us for more information.

What is the difference between a gasket and a packing?

What is the difference between a gasket and a packing?

We will also introduce the criteria that are clearly defined depending on the place of use!

Gaskets and packing are both sealing materials that prevent the leakage of liquids and gases, but they are clearly distinguished by the "movement" of the places where they are used. In simple terms, gaskets are used in stationary places, while packing is used in moving places. A gasket is a sealing material used in stationary parts. When fixing parts together with bolts or similar fasteners, it is inserted between them to eliminate gaps, preventing internal fluids from leaking and external foreign substances from entering. *For more detailed information, please refer to the related links. Feel free to contact us for further inquiries.*

What is the RCF (Refractory Ceramic Fiber) regulation?

What is the RCF (Refractory Ceramic Fiber) regulation?

We will also introduce what our company has implemented and the products in response to the RCF regulations!

As of November 1, 2015, the amendment to the Labor Safety and Health Act has made Refractory Ceramic Fibers (RCF) subject to regulations aimed at preventing health hazards to workers. With this amendment, RCF has been designated as a substance that requires labeling and classified as a Category 2 substance under the management of specific chemical substances, thus subjecting it to stricter preventive regulations. In response to this RCF regulation, Daiko has completely switched from traditional ceramic cloth to a safer, bio-soluble ceramic cloth. *For more detailed information, please refer to the related links. For further inquiries, feel free to contact us.*
