Products for Boiler Servicing

Hawleys has a large range of products that are used when servicing a boiler. The interval of when a boiler is serviced is different per manufacturer and boiler type, but this is quite often conducted on a quarterly interval. During these services, many items on the boiler are changed out on a schedule. There are also other items in steam systems that will be changed out on an ad hoc basis. Items commonly used during these periods include Gaskets, Lagging, Gauge Mounts, Gauge Mount Consumables, Gland Packings and even some Valves.

Gaskets 

When a Valve, Gauge Mount or Flange are undone from a piping system it is quite common to replace the gasket at the same time. This is the same for the boiler service industry. Most commonly this will be the gaskets on the Boiler Gauge Mounts if they are removed. These are usually Tanged Graphite but other options such as Expanded PTFE are also commonly used. Hawleys has a complete range of gasket materials for these applications and CNC cutting facilities for a fast turnaround.

Lagging 

When servicing a Boiler or a Steam System, if there is any damage to the existing lagging or any deficiencies it may need to be replaced. Hawleys has a complete range of high temperature lagging designed specifically for this. This includes Fiberglass Tapes (Woven & Ladder), Fiberglass Rope and Ceramic Blankets.

Ball Valves

Ball Valves are quite often used when servicing boilers or associated steam equipment. Usually high temperature three piece ball valves are used as isolation valves on boilers and two piece ball valves will be quite often used on water feed lines. From time to time these may need to be replaced. On three piece ball valves the tie rods can be removed and the seats replaced however on two piece it is usually easier to change the complete valve. Hawleys has both options available depending upon the requirement.

Globe Valves

It is very common for boilers and the surrounding install to have Globe Valves on them. These are used not only as an isolation valve but a valve that allows a degree of throttling. This can be used to regulate the flow to some degree or allow the system to achieve a soft start up. These are replaced on an ad hoc basis if the valve is passing or is damaged. If there is a complete refurbishment all valves are often replaced. Hawleys has its own range of Globe Valves designed specifically for the steam and boiler industry.

Check Valves

Check Valves are usually used on boilers and around the installation of these. During service these may need to be changed out, especially where the seat may have worn and the check valve is now passing. There are many different kinds of check valves used and it is quite common to change out for the same type if it has been working well. Most commonly these will be three piece threaded inline check valves but they can be a variety of different options.
