Product Description

Seamless CNG Cylinder Steel Pipe Od 267mm 255mm 232mm 457mm Grade 35CrMo 34CrMo4

PART I: PRODUCT INTRODUCTION
What is a high pressure cylinder tube?

High pressure gas cylinder tube is a kind of seamless steel tube, commonly known as seamless steel tube for gas cylinders, widely used in all kinds of high pressure vessel tanks, as well as industrial gas cylinders, fire cylinders, vehicle CNG cylinders, vehicle composite winding cylinders and other gas cylinders manufacturing.

What are the manufacturing processes of high-pressure gas cylinder tubes?

High pressure gas cylinder tube can be divided into hot rolled and cold drawn. Hot rolled gas cylinder tube is mainly used to manufacture all kinds of pressure vessels, cylinders and other products. Cold drawn gas cylinder seamless steel tube is mainly used to manufacture vehicle-mounted gas cylinders requiring light weight and thin wall thickness and steel liner circular winding vehicle-used CNG cylinders.

What are the production inspection and testing standards for high-pressure gas cylinder tubes?

The domestic standards are GB/T 18248 and GB/T 28884, and the corresponding foreign standards are JIS G 3429, ISO 11120, ASTM 372, etc

What are the main materials of high pressure cylinder tube at home and abroad?

The main materials of gas cylinder tube in China are 37Mn, 34CrMo4, 35CrMo, 30CrMnSiA, 30CrMo, 34Mn2V,

The main foreign standard material of gas cylinder tube is: 38Mn6, 30CrMo4, Group , 4130X, Grade C, Grade E, STH11, STH12, STH21, STH22


Characteristics and advantages of high-pressure gas cylinder tubes manufactured by our company: Raw materials provided by HengGang high-quality special steel and its high purity of steel, cold drawn cylinder tube, the tube body geometry size and the inner and outer surface quality, its wall thickness uniformity and high precision, light quality, productivity and yield is quite high, also facilitate cylinder manufactory convergent, and I produce cylinder pipe diameter can be done in 325 ~ 430, the minimum wall thickness of 3.5 mm, As a conventional specification of gas cylinders, the delivery time is faster.

1. Description: Honing is a kind of machining technology. Through honing head, the inner hole of cold drawn pipe is processed by reciprocating high-speed grinding technology, so that the inner hole can meet the requirements of tolerance size and surface roughness that we need.
Honed tube is a kind of smooth bore steel tube used to manufacture hydraulic cylinder barrels that is the core part of a piece of hydraulic cylinder. 
2. Commodity:  St52.4 Honed Hydraulic Cylinder Precision Pipe
3. Size range: Inside diameter: 25mm -500mm; Wall thickness: 2-50mm
4. Available steel grade: 
SAE/AISI: 
38Mn6,30CrMo4,Group ,4130X,Grade C,Grade E,STH11,STH12,STH21,STH22
 
DIN:  ST52, ST52.3, ST52.4
EN:  E355, C45E, 25CrMo4, 42CrMo4, CK45, S45C, E410, E470
GB:  37Mn,34CrMo4,35CrMo,30CrMnSiA,30CrMo,34Mn2V,
5. Manufacture method: Cold rolled, hydraulic cold drawn, hot rolled+deep hole boring
6. Production standard:
Seamless CNG Cylinder Steel Pipe Od 267mm 255mm 232mm 457mm Grade 35CrMo 34CrMo4
 
7. Bore treatment: Honing, skiving&roller burnishing
8. Bore roughness control: Ra0.25um max or Ra0, 35um max for honed tubes, Ra0.25um max for skived&roller burnished tubes. 
9. End finish: Plain ends with square cuts, free of burrs for honed tubes. Little bevelled ends for skived&roller burnished tubes. 
10. Standard export packing: In bundles tied with steel strips. Internal & external oil coating. Plastic caps on both ends. External packing by PVC bags and knit bags. 
11. Customized packing and marking can be provided upon request. 
12. H8 tolerance: 
ID range Tolerance ID range Tolerance
18< d ≤30 +0/+0.033 180< d ≤250 +0/+0.072
30< d ≤50 +0/+0.039 250< d ≤300 +0/+0.081
50< d ≤80 +0/+0.046 300< d ≤315 +0/+0.081
80< d ≤120 +0/+0.054 315< d ≤400 +0/+0.089
120< d ≤180 +0/+0.063 400< d ≤500 +0/+0.097
13. Difference between honed tube and skived & roller burnished tube: In hydraulic cylinder industry, there are 2 solutions for bore treatment: Honing, and skiving&roller burnishing. Honing or skiving&roller burnishing leads to different internal surface image, but both ensure good roughness.
