Yoshitake ES-10-200 is a sleeve type expansion joint designed for steam, air, cold and hot water, oil, and other non-dangerous fluids. It complies with SHASE-S003 standards and features a large expansion and compression length, which significantly reduces the need for multiple pipe joints and anchors in the piping system. The sleeve surface is hard chrome plated, providing outstanding corrosion and wear resistance for long-term reliability.

Features

1. Complies with SHASE-S003 Sleeve Type Expansion Joints.
2. Large expansion/compression length can lessen the pipe joint and anchor.
3. No need for lubrication and easy maintenance by original packing. Smooth sliding and excellent airtightness.
4. Outstanding corrosion resistance and wear resistance due to hard chrome plating on the sleeve surface.

Precautions before installation

1. Provide anchors, guides, and pipe supporting device when installing the product. The function of the product will not be fulfilled due to equipment breakage, piping bending, abnormal product growth, etc.
2. Please use the product within the range from the minimum length to the maximum length. If the product is not within the specified range, the product will not function due to abnormal expansion and contraction.
3. Install the product correctly so that the inlet and outlet are correct. There is a display on the body showing the direction of fluid flow. Installation in the wrong direction may not only affect the original performance, but may also lead to an accident.
4. Install so that there is no misalignment in both horizontal and vertical piping. Misalignment may lead to noise or damage from the inner cylinder, which may not only affect the original performance, but may also lead to an accident. In particular, vertical piping is prone to misalignment, so provide anchors, guides, and pipe supporting device to prevent misalignment.

Installing Anchors, Guides, and Pipe Supporting Devices

Secure anchors and guides are required to make full use of the function of the joint connected to piping. The piping system shall be equipped with main anchors at the following positions:

1. End part of straight piping with shut-off plate.
2. Portion of bent pipe where the flow direction changes.
3. The portion between two expansion joints where the piping systems are changed by reducer.
4. The portion of piping between two expansion joints where a valve is installed.
5. The entrance of a side branch containing an unrestrained expansion joint into the main piping.

Load Acting on the Main Anchor of Straight Pipe

Mount a main anchor at both ends of the piping, each branch point, and the location where a reducer or valve is installed. These main anchors need to be strong enough to withstand the force required to stretch or contract the sleeve plus the internal pressure thrust resulting from the effect of the internal fluid pressure.

F_MA = F_S + F_M + F_G

Where:

• F_MA: Load acting on the main anchor (N)
• F_S: Pressure thrust of expansion joint (N) = a × P × 100
• F_M: Frictional force of expansion joint (N)
• F_G: Frictional force of guide elements (N)
• a: Effective area of expansion joint (cm²)
• P: Internal pressure (MPa)

Caution on Vertical Piping

In case of vertical piping, the piping mass and fluid mass are further loaded, so when calculating the anchor strength, add them together. Make sure to install the product with no misalignment of the piping. Misalignment may lead to noise or damage from the sleeve.

Piping Example

Installation Interval of Guide Elements

In a piping using expansion joints for absorbing axial movements, guide elements (G) shall be installed to align the pipe joint and pipe and transmit the force necessary for axial movement smoothly to the anchor.

Keep the misalignment of 125A and smaller piping within ±2 mm and that of 150A and larger piping within ±3 mm. Adjust the parallelism of piping to ±0.5° or less.

Installation of Expansion Joints

The thermal expansion or contraction length of piping (Δℓ) shall be obtained according to the formula: Δℓ = β(T - t1)ℓ

Where:

• β: Linear expansion coefficient of piping (°C⁻¹)
• T: Maximum working temperature of pipe (°C)
• t1: Minimum working temperature of pipe (°C)
• ℓ: Length of piping (mm)

Table 2: Linear expansion coefficient of piping (×10⁻⁶/°C)

Temperature (°C)	Carbon steel, Low chrome steel	Austenitic stainless steel
0	10.75	16.27
100	11.53	16.84
200	12.24	17.25
220	12.38	17.32

Operating Procedure

Warning

1. Be sure to confirm that there is no leakage after ventilation. If there is a leak, retighten the bolts and nuts. (Tightening pressure may drop due to the packing properties during product transportation and installation.)
2. Do not cause the occurrence of water hammer. Otherwise, the expansion joint may be damaged, causing external leakage.
3. When using high temperature fluid, do not touch the product with bare hands. Failure to follow this notice may result in burns.
