CNG Cylinders For Small Industrial Users
Jul 26, 2017



CNG is the English abbreviation of compressed natural gas. Compressed natural gas generally refers to the gaseous gas (methane as the main ingredient) that can be used for vehicle engines as fuel by multi-stage pressurization to about 20MPa. CNG cylinders-a high-pressure vessel used to store compressed natural gas, CNG Steel Cylinders a high-pressure container with inflammable and explosive gases that is an explosive and dangerous pressure vessel. The gas storage pressure of the car gas cylinder is 20MPa. CNG cylinders are divided into four categories

The first type is steel or aluminum alloy metal bottle (CNG-1);

The second type is steel or aluminum lined with a barrel through the "hoop-wound" resin impregnated with long fiber reinforced composite gas cylinders (CNG-2);

The third category is steel or aluminum lined with "whole winding" CNG Steel Cylinders resin impregnated long fiber reinforced composite gas cylinders (CNG-3);

The fourth category is plastic lining gaga "whole winding" CNG Steel Cylinders resin impregnated long fiber reinforced composite gas cylinders (CNG-4).

Characteristics of CNG cylinders

Non-standard design, flexible and changeable configuration mode, according to the user's use of gas design;

Multi-port design to ensure safe storage and transportation;

The gas storage is flexible and changeable, which reduces the cost of user investment;

Light weight, can be transported by a variety of goods vehicles;

Beautiful appearance, a unique rain-proof design;

Especially suitable for CNG field;

First, CNG cylinder gas supply system process

The CNG cylinder trailer loaded from the compressed natural gas station is transported by road or waterway to the supply site of the central town, CNG Steel Cylinders which is discharged through a high-pressure hose and a quick-fitting joint, CNG first-class heat exchanger, and then into the A-level regulator decompression, followed by the two-level heat exchanger, two-level regulator, or after the three-level regulator, CNG Steel Cylinders pressure to the town pipe network operating pressure, after the metering into the town transport distribution network.

II. Characteristics of gas supply for CNG cylinders

1. Stable price and remarkable economic benefit. CNG Cylinder gas supply system can replace the LPG bottle Group Gas supply system, the gas source price is significantly lower than the LPG, the price of gas users is relatively low, the user can accept, the economic benefits of gas enterprises are also significantly improved.

2. Convenient and flexible gas supply. According to the different amount of gas users can configure different cylinders, no power, gasification complete, no residual liquid, suitable for small industrial users and community gas supply.

3, less investment, can be used as one of the means of gas enterprise market development, for the city gas pipeline network is not exposed to the regional gas supply, when the time is ripe to directly replace the pipeline natural gas.

Three, CNG cylinder gas supply should pay attention to problems

(1) The total volume of gas cylinders should not be greater than that of $number M3, and the total geometrical volume of the cylinder group should not be greater than 4 m3.

(2) The total storage volume of gas cylinders should be calculated at 1.5 times times the monthly average daily gas supply.

(3) CNG cylinder gas supply station should be set at the edge of the gas supply area, the scale of gas supply should not be greater than 1000 households.

(4) The cylinder group shall be set at the station fixed location. The location and construction of gas cylinder group and natural gas bleeder, pressure regulating device to open flame emitting spark shall not be less than the "town Gas Design Code" (gb50028-2006) Compressed natural gas cylinder Group Gas Supply Station table 7.4.3.

(5) Outdoor compressed natural gas pipeline should be buried, CNG Steel Cylinders the top of the pipe from the ground depth should not be less than 0.6m.
