01 / APPLICATION & COMPONENTS

Seawater intake & piping castings

At the seawater intake, casting requirements arise in isolation valves, strainer housings and pipe connections. Boat thru-hulls and seacocks are shown separately from commercial-ship sea valves; hull sea chests are not treated as generic bronze castings.

CASTING COMPONENT

Strainer housing

Seawater intake or circulation pipework

Contains the removable basket and directs seawater through it. The basket, cover and housing may use different materials.

Material options

UNS C84400Leaded semi-red brass

Used in some marine strainer housings. Offers good casting and machining characteristics; seawater service and lead restrictions require project-specific review.

Select the grade against the drawing, duty conditions and applicable material standard. These candidates are not interchangeable and do not establish confirmed manufacturing scope.

Information for your quotation

Application duty: Identify vessel type, below- or above-waterline position, connected alloys, thread or flange standard, seawater condition and design pressure.
Housing & connections: Drawing, inlet/outlet sizes, flange or thread standard, installation envelope and flow direction.
Basket & cover fit: Basket seating dimensions, removal clearance, cover bolt pattern and gasket interface.
Operating conditions: Design pressure/temperature, flow rate, water quality, basket material and housing pressure-test requirements.
Material specification: Alloy grade, governing material standard, casting condition and any restricted substances.
Order & acceptance: Drawing revision, quantity, delivery condition, critical tolerances, inspection methods and required documentation.

Custom casting enquiries are welcome to your drawing, specified alloy grade and applicable material standard. Manufacturing scope is confirmed during quotation.

CASTING COMPONENT

Seacock body

Boat below-waterline intake

Forms the housing of a boat seacock at the hull connection. Commercial-ship sea valves and hull sea chests are separate component categories.

Material options

UNS C84400Leaded semi-red brass

Used in some marine strainer housings. Offers good casting and machining characteristics; seawater service and lead restrictions require project-specific review.

Select the grade against the drawing, duty conditions and applicable material standard. These candidates are not interchangeable and do not establish confirmed manufacturing scope.

Information for your quotation

Application duty: Identify vessel type, below- or above-waterline position, connected alloys, thread or flange standard, seawater condition and design pressure.
Body configuration: Base flange, mounting holes, internal passages and closure arrangement.
Hull & pipe interfaces: Thru-hull thread standard, hose or pipe port, installation thickness and available space.
Service requirements: Below-waterline duty, applicable equipment standard, pressure and required inspection.
Material specification: Alloy designation, governing standard, casting condition and any restricted substances.
Order & acceptance: Drawing revision, quantity, delivery condition, critical tolerances and required inspection records.

Custom casting enquiries are welcome to your drawing, specified alloy grade and applicable material standard. Manufacturing scope is confirmed during quotation.

CASTING COMPONENT

Globe-valve body

Drawing-defined globe valve

Forms the pressure boundary and flow passage, with interfaces for the bonnet, pipework and valve seat.

Material options

EN CC491K · CuSn5Zn5Pb5-CLeaded gunmetal

Used in pump and valve castings for its castability, machinability and corrosion resistance. Confirm service conditions and any restrictions on lead.

UNS C95800Nickel-aluminium bronze

An option for seawater-wetted castings where corrosion resistance and strength are important. Casting condition, water quality and flow conditions require review.

Select the grade against the drawing, duty conditions and applicable material standard. These candidates are not interchangeable and do not establish confirmed manufacturing scope.

Information for your quotation

Application duty: Identify vessel type, below- or above-waterline position, connected alloys, thread or flange standard, seawater condition and design pressure.
Valve configuration: Drawing and 3D model; straight or angle pattern, nominal bore, face-to-face dimension and port geometry.
Connections & seat: Flange or thread standard, bonnet bolt pattern, seat arrangement, machining datums and sealing surfaces.
Design & acceptance: Design pressure/temperature, applicable valve standard, pressure-test scope and inspection acceptance criteria.
Material specification: Alloy grade, governing material standard, casting condition and any restricted substances.
Order & acceptance: Drawing revision, quantity, delivery condition, critical tolerances, inspection methods and required documentation.
