Steel packaging requirements of the basic two categories: one is the common type of bundling , the other is similar container with crates loaded 5.1 5.1.1 bundled package to avoid damage to the pipe by baling and transportation process, bundling signs to uniform and consistent . 5.1.2 the same should be the same pipe bundle heat number ( batch ) , with the steel grade , the same specification steel , should not be mixed furnace ( batch ) bundling , inadequate bundle should be labeled small bundle . 5.1.3 each bundle should not exceed the weight of steel 50kg. After the user agrees to increase bale weight, but the most important can not exceed 80kg. 5.1.4 for steel strapping flat end when one end should be aligned , align the ends of the pipe ends differ by less than 20mm, each bundle is less than the difference in length of steel pipe 10mm, but the length difference between the length of pipe in accordance with the usual order of each bundle of steel is less than 5mm, a bundle of steel minister of the longest and not more than 10mm. 5.2 bale form 5.2.1 or greater pipe length 6m, playing at least 8 per bale strapping , divided into three groups , labeled as 3-2-3 ; pipe length is less than 6m, at least a dozen 5 per bundle strapping , divided into three group , labeled 2-1-2 ; ( figure 1 pipe length greater than or equal to 5 meters in length steel strapping strip location diagram) pipe length is greater than equal to 3m, at least three dozen per bundle strapping , divided into three groups , labeled 1-1-1 .

Hdpe pipe performance and features:
1. Environmental material.
Hdpe is a kind of no-toxic, tasteless and unharmful chemical material, and hdpe pipe, inherits those typical features nicely.
2. Good flexibility.
When it is used in dredging pipe, the rubber flexible connectors can be saved because of its good flexibility.
3. Low hydraulic resistance.
The smooth inner wall make the water transportation capacity improve more than 30% under the same condition.
4. No leakage.
The technics of hot-fusion and electric-fusion make sure the the strength of welding point is stronger than the body pipe itself.
5. High abrasion performance.
Its wear resistance is 4 times as the steel pipe.
6. Anti-corrosion and crack growth resistance.
7. Long lifetime durable in use.
50 years at least.
8. Economy
Low delivery, installation and maintenance cost.

Expansion joints are specially engineered products inserted in a rigid piping system to achieve one or more of the following:
Absorb movement
Improved thermal stability
Relieve system strain due to thermal change, load stress, pumping surges, wear or settling
Reduce mechanical noise
Compensate for misalignment
Eliminate electrolysis between dissimilar metals
They are ideally suited for hundreds of applications in a wide range of industries, including:
Power Generation
Pulp and Paper
Chemical Processing
Water/Waste Water
Marine
Mining
Heating, Ventilating, and Air Conditioning

A flange is a method of connecting pipes, valves, pumps and other equipment to form a piping system.
It also provides easy access for cleaning, inspection or modification. Flanges are usually welded or screwed.
Flanged joints are made by bolting together two flanges with a gasket between them to provide a seal.
