Our Complete Range of Cryogenic Manifolds & Spools
AMI supplies a full spectrum of manifold and spool products for both industrial and medical applications. Here's what we offer:
1. Industrial & Medical Cylinder Manifolds
Up to 4,500 psig of cylinder filling and charging is possible with our industrial and medical manifolds. They accept a variety of cylinder bank sizes, ranging from 10×10 to 80×80 cylinder manifolds, and are available in floor-mounted or wall-mounted configurations. Perfect for industrial facilities, hospitals, labs, and gas stations.
2. Gas & Vacuum Control Manifolds
Integrated gas and vacuum control panels with alarm systems are part of AMI's control manifolds. When the manifold starts to draw from the secondary bank or when the cylinder pressure drops to a predetermined level, the alarm panel alerts the operator, providing your team all the information they need to take action before a supply interruption happens.
3. High-Purity Analyzer Manifolds
Designed for precision gas analysis applications, our analyzer manifolds analyze the mix ratio of gases inline. They are excellent for R&D labs, quality control settings, and specialty gas distribution. They are offered in brass and stainless steel (MOC) formats with single, double, and quadruple cylinder arrangements.
4. Custom Engineered Piping Spools
The diameter, length, material grade, kind of end connector, and pressure rating of our specially designed piping spools are all made to your exact specifications. Before being delivered, these spools are checked to ensure they meet all applicable cryogenic piping standards and fit easily into your vacuum jacketed pipe systems.
5. Manifolds & Spools Vaporizer Integration
In order to complete the connection between your storage tanks, distribution manifolds, and ambient or electric vaporizers, AMI also provides and installs manifolds and spool vaporizer assemblies. This guarantees a constant supply of gas under pressure control with no product loss.

What Is the Standard for Cryogenic Piping?
"What is the standard for cryogenic piping?" is a common question from engineers and compliance teams. The following are the main guidelines that control cryogenic pipe system design, construction, and testing:
- ASME B31.3: Process Piping — widely applied for cryogenic process piping in industrial facilities.
- ISO 21013: Cryogenic vessels — hose assemblies and piping for stationary use.
- EN 13480: Metallic industrial piping standard used in European and GCC projects.
- BS 8010: Specification for pipelines, applicable for medical gas distribution systems.
- NFPA 50 & 55: For bulk storage and handling of cryogenic fluids in the US market.
All cryogenic manifolds and specially designed piping spools are designed and manufactured by AMI in accordance with the relevant regulations for your area and use. Pressure test results, weld inspection records, and material certificates are all included in our documentation package.
630 Series Cryogenic Manifold — Built for High-Performance Distribution
Trusted by industries across the GCC — the 630 Series delivers where it counts.
High-pressure cryogenic distribution systems frequently use the 630 Series cryogenic manifold, a professional-grade manifold valve assembly. For cryogenic pipes that must function dependably at extremely low temperatures—without seat leakage or operational failure—the 630 Series cryogenic manifold is especially made for use with manifold valves. Key features of the 630 Series include:
- Compatible with many cryogenic media, including LOX, LIN, LAR, and LCO₂
- Low operating torque and positive shut-off
- Multiple port combinations are available to accommodate the size of your cylinder bank
- For secondary bank switchover, it works in tandem with integrated alarm panel
If you're building a brand-new stationary cryogenic storage tank distribution system from the ground up or improving an old one, the 630 Series cryogenic manifold is a reliable choice. Contact AMI to talk about your settings.
Cryogenic Tank Maintenance — The Role Your Manifold Plays
Inspection and maintenance of the manifold assemblies attached to your stationary cryogenic storage tanks are part of routine cryogenic tank maintenance. An unmaintained manifold may result in:
- Increased product evaporation losses (boil-off) due to excessive heat leakage into the storage vessel
- Uncontrolled gas escaping due to valve seat deterioration and leakage
- Oxygen service line corrosion or contamination poses a major risk to public safety
- Overpressure is more likely when the pressure relief mechanism is circumvented
AMI's field service team offers complete cryogenic tank maintenance packages that include manifold inspection, valve replacement, pipe spool checks, and complete recommissioning. Not only do we operate with AMI-supplied equipment, but we also deal with manifolds attached to stationary cryogenic storage tanks from all major manufacturers.

Insulated Piping for Cryogenic Liquids — Making the Right Connection
The quality of a manifold depends on the piping system to which it is connected. For cryogenic liquids, AMI provides and installs insulated piping, such as vacuum jacketed piping systems (VJP), which offer better thermal performance than foam-insulated substitutes.
Vacuum jacketed pipe (VJP) benefits:
- Thermal efficiency: 10× better than conventional foam insulation — dramatically reducing product boil-off.
- No condensation: The vacuum jacket prevents moisture condensation on the outer surface, protecting your facility floor from ice formation.
- Extended maintenance intervals: VJP systems require far less routine maintenance than foam-insulated lines.
- Clean appearance: Suitable for food, pharma, medical, and semiconductor environments where cleanliness is paramount.
AMI creates specially designed piping spools to fill every void in your vacuum jacketed piping systems, whether you require extensive distribution runs throughout a plant or small spool connections between tanks and manifolds.

What are the components of a cryogenic pump?
A cold end cylinder, piston/plunger, suction and discharge check valves, cryogenic seals, warm-end drive assembly, pressure safety valve, and inlet strainer make up a cryogenic pump. For a completely integrated system, AMI offers complete cryogenic reciprocating pumps in addition to manifolds.
Which materials can be used in cryogenic service?
The most popular materials are aluminum alloys, nickel-based alloys, copper alloys (brass), and austenitic stainless steel (SS 304/SS 316). The choice of material is influenced by the pressure rating, fluid compatibility, and operating temperature. The best option for your particular cryogenic liquid gases is recommended by AMI.
What is a cryogenic valve for liquid nitrogen?
It has a full-bore design, an enlarged bonnet, and low-temperature-rated seats and seals (PTFE or metal). For cryogenic plumbing, AMI provides manifold valves that are appropriate for LIN, LOX, LAR, and LCO₂ services.
What is the 630 Series cryogenic manifold?
A common high-pressure manifold valve assembly in cryogenic cylinder distribution systems, the 630 Series cryogenic manifold has a rating of up to 4,500 psig. It is renowned for its ability to shut down positively and for working with a variety of cryogenic liquid gases.
