Pipe, fittings, valves, hoses, sanitary and fresh water parts, fans, ducting and HVAC spares delivered to commercial vessels at U.S. ports.
Piping, plumbing and ventilation systems run through every part of a ship, from the engine room to the galley and accommodation. Leaking valves, corroded fittings and failed fans are everyday maintenance jobs, and the crew needs the right parts to fix them during the port call. Alpha Ship Supplies is a marine plumbing supplies and ventilation parts supplier for vessels calling at ports across the United States. Our Houston team matches each fitting, valve and fan to the size, material and pressure rating on board, quotes it with your other stores and delivers it to the berth.

On a ship, a fitting that is almost right is wrong. Thread standards, pipe schedules, flange ratings and materials all vary between systems, and the wrong part can leak or corrode quickly in sea water service. Ventilation and air conditioning parts must match the fan, motor and unit already fitted, or the system will not perform.
Engineers and superintendents send their plumbing and ventilation requisitions to us because:
For fleets with sister ships, we can record the pipe standards and fan models fitted on board, so repeat orders for the same valves, gaskets and filters are quoted faster each time the vessel calls.
Send the system, size, material and photos of the failed part. We confirm what can be supplied before sailing.
We supply plumbing and ventilation items for engine room, deck and accommodation systems:
If an installed valve or fan is obsolete, we can help identify a current replacement with matching connections and performance, and list any adapter pieces needed to fit it.
Tankers and chemical carriers need valves and fittings suited to cargo, inert gas and deck piping, plus explosion-protected ventilation in hazardous areas. Bulk carriers rely on hold ventilation fans and bilge piping that see heavy wear. Container ships and car carriers run large cargo ventilation systems where fan failures affect cargo care. Passenger and crew-heavy vessels depend on sanitary, fresh water and air conditioning systems for comfort and hygiene. Yachts and workboats use compact plumbing, marine toilets and small ventilation fans that need quick replacement. Each requisition is read with the vessel type and system in mind.
Offshore and fishing vessels working out of Gulf Coast ports also order regular hose, fitting and fresh water parts on the same terms.
Most requisitions combine piping, valves and ventilation consumables. We quote them on one document and deliver them with your other stores.
Complete valves plus seats, discs, stems, packing and actuator parts for sea water, fresh water, fuel and steam systems.
Threaded, welded and flanged fittings matched to pipe size, schedule and material, with gaskets and bolts to complete the joint.
Rubber, PVC and reinforced hoses for water, fuel and air, with stainless clamps and fittings. See hardware and fasteners.
Marine toilets, vacuum sewage system spares, taps, showers, water heaters and fresh water system parts for accommodation and galley.
Ventilation fans and motors, ducting, flexible connectors, dampers, grilles and air filters for engine rooms, holds and accommodation.
Air conditioning and provision plant consumables: filters, belts, gaskets and service parts. See electrical supplies.
Accurate specification is the foundation of every plumbing and ventilation quotation.
We check nominal size, pipe schedule, thread type and flange standard. Ships built in Europe or Asia often use metric and JIS or DIN standards, while U.S. stock is usually ANSI, so we flag any differences before quoting.
Sea water systems need corrosion-resistant materials such as bronze or copper-nickel, while fuel and steam lines need appropriate ratings. We match material to service, not just to size.
For fans and air conditioning parts we work from the unit nameplate, motor rating and voltage, so replacements fit the existing mounting and power supply.
Parts are packed by system, delivered with your other stores at the berth, and listed by size and material on the delivery note.
Valves and fittings for steam, compressed air and fuel service are quoted with their pressure and temperature ratings stated on each line. If you need test certificates or material certificates for class records, tell us on the requisition and we confirm what is available before you approve the order.
Tell us the standard used on board. Where U.S. stock differs, we quote adapters or metric parts so the repair fits.
A leaking sea water valve, a failed engine room fan or a broken sanitary system can need fixing before the vessel sails. Mark the requisition URGENT, include the size, material, ETD and port, and we will tell you quickly what can realistically be sourced and delivered before departure, and what is better planned for the next port. Requisitions can be sent through our form at any time, and urgent requests are prioritized by ETD.
Temporary repair items such as pipe repair clamps, wraps and epoxy kits can also be supplied to keep a system running until a permanent fix is made.
Ships built in Japan, South Korea, China and Europe often use JIS or DIN pipe and flange standards, and their technical departments sit in Greece, Germany, Singapore or Tokyo. We work by email across time zones and quote against the standard used on board, so approvals are fast and parts fit.
Where metric parts are not readily available in the United States, we show the lead time clearly and offer adapter solutions where they are acceptable to the technical department.
Container ships, car carriers and bulk carriers carrying sensitive cargo depend on cargo ventilation to control condensation and fumes. When a hold fan or damper fails, the cargo officer needs a quick replacement. We quote fan motors, impellers and dampers against the unit nameplate and can deliver them with the rest of your stores at the next U.S. berth.
Most plumbing quotation delays come from missing specification details. These steps avoid them.
Measure the outside diameter of the pipe, note the thread or flange type and photograph the part next to a tape measure.
Tell us what the system carries, for example sea water, fresh water, fuel, steam or sewage, and its working pressure.
Confirm whether the ship uses metric (JIS or DIN) or imperial (ANSI) fittings. This avoids receiving parts that will not connect.
Add gaskets, bolts, clamps and sealant to the list so the repair can be finished in one go.
Vessel name, IMO, berth or terminal, ETA/ETD, agent details and the item list with quantities. For spares add maker, model and part number.
Every line priced, substitutes and long-lead items flagged, and delivery or launch charges confirmed up front.
Approve by email or purchase order. Suppliers and transport are booked the same day.
Stores arrive in the agreed slot at your berth at any U.S. port we serve with a delivery note matching your requisition.
Invoice and supporting documents for your accounts, audits and vessel records.
Clear size, standard and material details at step one are the biggest factor in quotation speed. Every item is checked against the requisition before dispatch, and any substitution or adapter is shown on the delivery note before the engineer signs.
Send the size, standard, material and quantity to Alpha Ship Supplies. We quote the fittings and valves and deliver them to the vessel at its berth at U.S. ports we serve.
Yes, where available. We confirm the standard used on board and show lead times for metric parts, or offer adapters where the technical department accepts them.
Ventilation fans and motors, ducting, flexible connectors, dampers, grilles, air filters and air conditioning service parts.
Yes. We supply marine toilets, vacuum sewage system spares, taps, showers and fresh water system parts.

Yes. Plumbing and ventilation items are delivered with your provisions, deck and engine stores on one delivery to the vessel.
Yes. Filters, belts, gaskets and service parts for air conditioning and provision refrigeration plants are quoted against the unit details.
