Manufacture of cylinders – the main material of cylinders

First, the main material of the gas cylinder

Reasonable selection of materials is the prerequisite to ensure the quality of gas cylinders.

Basic requirements for cylinder body materials

1. Have enough strength, especially high pressure cylinders should have high strength and appropriate flexion strengthening, in order to reduce the weight of cylinders, and give full play to the potential of materials;

2. Having certain plasticity and toughness; And has good low temperature performance, to adapt to the characteristics of large flow of gas cylinders and complex use environment:

3. The material is more stable and uniform; Good anti-fatigue performance, can ensure the fatigue life of the whole service period;

4. Good corrosion resistance;

5. Easy to manufacture and processing, high pressure cylinders should have good malleability, low pressure welding cylinders should have good weldability;

General requirements knowledge points

3 、 الحد الأدنى لكمية الطلب: 100 فقط

4、Common nonconformance points in gas bottles production :

— Manufacturing imperfections of gas bottles:

a/Excessive grinding or machining: Local reduction of wall thickness by grinding or machining

This is not allowed when the cylinder wall thickness is reduced below the minimum design thickness

Often seen in refurbished cylinders, with expired cylinders, the stencil erased, re-stencil.

b/Rib :A longitudinal raised surface with sharp corners having a height of 3% or more than the wall thickness (see Figure A.3)

⎯ Inside imperfection: when height exceeds 5 % of wall thickness or when length exceeds 10 % of the length of the cylinders

⎯ Outside imperfection: when height exceeds 5 % of wall thickness or when length exceeds 5 times the thickness of the cylinders.
