Cast Iron Bucket Type Steam Trap (Screwed) Supplier
Cast Iron Bucket Type Steam Trap (Screwed) is designed to discharge condensate from suitable steam systems while helping prevent the unnecessary loss of live steam. Its inverted-bucket operating mechanism responds to changes in steam and condensate conditions to control the discharge cycle.
The referenced product specification describes a cast-iron body and bolted cover, female BSP screwed ends, and renewable stainless-steel working parts. Allarakhu and Sons provides industrial product enquiries from Surat, Gujarat, for buyers looking to confirm product specifications and sourcing requirements.
Product Overview
The Cast Iron Bucket Type Steam Trap (Screwed) uses an inverted bucket mechanism to operate the trap’s internal valve. As condensate enters the trap, the bucket’s position changes and allows condensate to discharge. Steam entering the bucket changes its buoyancy and operating position, helping the valve close and limit live-steam loss under suitable operating conditions.
The sourced model features a cast-iron body and cover with stainless-steel internal working components. Its female BSP screwed ends are intended for compatible threaded pipe connections. The bolted cover provides access to the internal assembly for inspection and maintenance in accordance with the manufacturer’s instructions.
This product is intended for steam service. Before selecting it, verify the actual operating pressure, temperature, condensate load, connection size and system backpressure against the product’s rated limits.

Design / Construction
Cast-Iron Body and Cover
The product specification identifies cast iron for both the body and cover. The source lists IBR 86 to 93 Grade A for these components. Confirm the applicable documentation for the actual supplied model if certification or traceability is required for a project.
Inverted-Bucket Mechanism
The inverted-bucket design uses the position and buoyancy of the internal bucket to operate the valve. This mechanism responds to the presence of condensate and steam within the trap, supporting automatic condensate discharge under suitable operating conditions.
Stainless-Steel Working Parts
The source specifies stainless-steel working components, including Type 304 valve parts and a Type 304 valve seat. It also lists a Type 410 stainless-steel plug. These material details should be checked against the current product datasheet for the exact configuration being supplied.
Bolted Cover
The bolted cover provides access to internal parts for inspection and servicing. Follow the manufacturer’s maintenance procedure and ensure the trap is safely isolated, depressurised and cooled before service.
Pressure Information
The product source specifies these pressure values:
-
Maximum working pressure: 10.55 kg/cm²g (150 psig)
-
Shell hydrostatic test pressure: 21.10 kg/cm²g (300 psig)
These figures describe different conditions. The hydrostatic shell test pressure must not be treated as the allowable working pressure.
When selecting the trap, check the system’s normal and maximum steam pressure, pressure differential across the trap, condensate backpressure and start-up conditions. Confirm suitability with the current manufacturer datasheet and the operating requirements of the installation.
Applications
The Cast Iron Bucket Type Steam Trap (Screwed) is intended for suitable steam applications where condensate needs to be removed from a steam system.
Potential application areas include:
-
Steam distribution lines.
-
Condensate drainage points in suitable steam pipework.
-
Industrial process steam systems.
-
Steam-line maintenance and replacement projects.
-
Plant utility systems that operate within the trap’s rated limits.
These are general application contexts for the product type. Confirm suitability for the specific equipment, condensate load, operating pressure and backpressure before installation. The referenced product listing identifies steam as the suitable service.
Product Selection Guide
Choose the appropriate trap by checking the following:
-
Operating pressure: Confirm that the normal and maximum steam pressure remain within the rated working limit.
-
Temperature: Verify that the operating temperature does not exceed the listed maximum of 220°C.
-
Condensate load: Establish the expected condensate quantity during normal operation and start-up.
-
Pipe size: Match the trap’s nominal size to the intended pipeline connection.
-
Thread compatibility: Confirm the female BSP connection is compatible with the existing pipework.
-
Backpressure: Consider the pressure in the condensate return system, as it affects trap operation.
-
Material requirements: Check the cast-iron body and stainless-steel internal materials against the system conditions.
-
Maintenance access: Allow sufficient space for inspection and servicing of the bolted-cover assembly.
For critical steam applications, use the manufacturer’s sizing and installation guidance rather than selecting a trap by pipe size alone.
