2. Product Information
2.1 Description
The PC10HP pipe connector is designed for use with the universal connector steam traps listed above, operating up to the maximum pressure/temperature limits of the selected steam trap. The connector can be installed in any vertical or horizontal pipeline, and the steam trap can be rotated through 360° to ensure correct orientation during operation.
The principle is that the pipe connector can be fitted into the pipeline without installing the steam trap, which is subsequently connected using only two bolts. The steam trap can be removed/replaced simply and quickly to minimise system downtime and reduce maintenance resources.

3. Installation
Note: Before carrying out any installation, observe the “Safety information” in Section 1.
To ensure that the rotary connector steam trap operates correctly and effectively removes condensate, several conditions must be met. Refer to the installation and maintenance instructions, product markings and Technical Information sheet to check that the product is suitable for the intended installation:
3.1 Check the materials and maximum pressure/temperature values. If the maximum operating limits of the product are lower than those of the system in which it is installed, ensure that a safety device is included in the system to prevent overpressure.
3.2 The correct steam trap and end connections must be selected to meet the system design conditions.
3.3 The steam trap connector bolts are supplied with the selected steam trap.
3.4 The connection between PC10HP and the steam trap is sealed with a high-integrity spiral-wound gasket. During installation, the gasket faces must be protected from damage to the steam trap gasket face caused by welding spatter, impact or similar hazards. Therefore, particular care is required when installing PC10HP in the pipeline. It is recommended that the steam trap be installed as soon as PC10HP has been installed in the pipeline. Alternatively, the steam trap may be connected to PC10HP before installation.
3.5 Determine the correct installation position and fluid flow direction. PC10HP must be installed in the direction indicated by the arrow. The flow direction may be horizontal (in either direction), vertical or inclined. The flow direction is clearly marked on the steam trap body or pipe connector.
Note: Unless otherwise stated in the specific installation and maintenance instructions supplied with the product, the connection face of the selected universal connector steam trap must always be in a vertical plane.
3.6 Before installation in steam or other high-temperature applications, remove the protective covers from all connections, where applicable.
3.7 Suitable isolation valves must be installed to enable safe maintenance and replacement of the steam trap. When the steam trap discharges into a closed return system, a check valve should be installed downstream to prevent backflow.
3.8 Always open the isolation valves slowly until normal operating conditions are reached - this will prevent system shock. Check for leaks and correct operation.
3.9 Always ensure that the correct tools, safety procedures and protective equipment are used.
3.10 When installing socket-weld versions, welding must be carried out using a qualified welding procedure in accordance with recognized standards.
3.11 Pipe welding for socket-weld versions
It is difficult to provide a general welding procedure covering the requirements of different national and international standards and codes - particularly in relation to the welding process, welding conditions (number of passes, welding consumable size, current, voltage and polarity), welding consumable storage, and welding consumable manufacturer/model, as there are many applicable welding consumable suppliers.
Welding recommendations based on British Standards are available. Please contact Spirax Sarco to discuss your welding requirements. Welding may be carried out in accordance with the applicable ASME IX or BS EN standard.
Important notes
- If the steam trap discharges to atmosphere, ensure that it discharges to a safe location. The temperature of the discharged fluid may be as high as 100 °C (212 °F).
- After installation, it is recommended that the PC10HP pipe connector be insulated to minimize radiant heat loss and protect personnel from the risk of burns. Note that some steam trap types should not be insulated.
4. Commissioning
After installation and maintenance, ensure that the system is fully operational. Test any alarm or protective devices.
5. Available spares and maintenance
Please note that the PC10HP pipe connector has no spare parts.
If spare parts are required for the steam trap connected to PC10HP, we recommend referring to the installation and maintenance instructions for that specific product.
