Introduction

Vacuum Insulated Piping System, namely Vacuum Jacketed Piping System, is constructed in a high vacuum and multi-layer multi-screen special insulated materials, and passes through a series of extremely strict technical treatments and high vacuum treatment, which is used for LO₂, LN₂, Lar, LH₂, LHe and LNG.

Three Connection Types

In order to maximize the different needs of customers, Vacuum Insulated Pipe has developed three connection types, namely Vacuum Bayonet Connection Type with Clamps, Vacuum Bayonet Connection Type with Flanges and Bolts and Welded Connection Type. They have different advantages and are suitable for different working conditions.

	Vacuum Bayonet Connection Type with Clamps	Vacuum Bayonet Connection Type with Flanges and Bolts	Welded Connection Type
Connection Type	Clamps	Flanges and Bolts	Weld
Insulation Type at joints	Vacuum	Vacuum	Perlite or Vacuum
On-site Insulated Treatment	No	No	Yes, perlite filled into or vacuum pump out from the Insulated Sleeves at joints.
Nominal Diameter of Inner Pipe	DN10(3/8")~DN25(1")	DN10(3/8")~DN80(3")	DN10(3/8")~DN500(20")
Design Pressure	≤8 bar	≤16 bar	≤64 bar
Installation	Easy	Easy	Welder
Length	1~8.2 meter
Material	Stainless Steel 304, 304L, 316, 316L
Medium	LN2, LOX, LAr, LHe, LH2, LNG

Nominal Diameter of Inner Pipe:

Recommended ≤ DN80 or 3". Or selects the Welded Connection Type (from DN10, 3/8" to DN500, 20"), Vacuum Bayonet Connection Type with Clamps (from DN10, 3/8" to DN25, 1").

Nominal Diameter of Outer Pipe:

Recommended by the Enterprise Standard of HL Cryogenic Equipment. It also can be produced according to requirement of the customer.

Design Pressure:

Recommended ≤ 16 bar. Or selects Welded Connection Type (≤64 bar).

Material of Outer Pipe:

Without special requirement, the material of inner pipe and outer pipe will be selected the same.

Power Condition:

The site needs to supply power to the vacuum pumps and inform HL Cryogenic Equipment the local electricity information (Voltage and Hertz)

Dynamic and Static Vacuum Insulated Piping System

	Dynamic Vacuum Insulated Piping System	Static Vacuum Insulated Piping System
Introduction	Compared with Static Vacuum System, the vacuum degree of Dynamic Vacuum System is more stable and does not decrease with time.	VJP completes the vacuum insulation work in the manufacturing plant.
Advantages	Recommended to install in a place where the room is too small for future maintenance.	More economical investment and simple on-site installation
Vacuum Bayonet Connection Type with Clamps	Applicative	Applicative
Vacuum Bayonet Connection Type with Flanges and Bolts	Applicative	Applicative
Welded Connection Type	Applicative	Applicative

Dynamic Vacuum Insulated Piping System: Consist of Vacuum Insulated Pipes, Jumper Hoses and Vacuum Pump System.
