DIFFERENCES BETWEEN STEEL DREDGING PIPE AND PE DREDGING PIPE

Dredged steel pipes are used mainly to clean and transport silt, mud and other mixed materials from steel pipes.
Dredging a project to dredge, widen, or dig deep water areas such as rivers and lakes, using manpower or machinery to carry out underwater earthwork excavation. In a broad sense, dredging includes reef and beach blasting by underwater blasting. Artificial excavation is only applicable to small rivers with cutoff construction. All kinds of dredgers are widely used in mechanical construction, sometimes also with cable shovel and other onshore construction machinery. Mechanical dredging began in 1600, during the construction of The Dutch Port of Rotterdam, the prototype of the chain bucket dredger appeared. China began construction of dredgers on the Huangpu River in 1889. In 1929, the chain bucket dredger was built in Jiangnan Shipyard. In the early 1980s, China had a mechanical dredging capacity of about 300 million cubic meters per year.
use
Dredged steel pipe is widely used in beach, river, waterway, urban environmental protection, engineering construction and other fields.
 
(1) Dredger, according to the working principle and soil conveying mode, divided into mechanical type and hydraulic type. Mechanical dredger with scoop or shovel directly from the water to dig and lift the soil, chain bucket, grab bucket, bucket wheel, etc. Hydraulic type dredger USES high pressure water to flush mud or use reamer, harrow head to cut mud, and then use mud pump to suck mud, through dredged steel pipe transport discharge, also known as suction suction type dredger, there are splice suction type, rake suction type, no reamer type, pneumatic type, etc. Dredgers can be divided into self-propelled and non-self-propelled dredgers, and non-self-propelled dredgers need tugboats.
(2) water operations ship, such as survey ship, crane ship, drilling and blasting ship, anchor boat, etc.
Auxiliary vessels, including tugboats, supply vessels such as oil and fresh water barges, mud barges, barges and living vessels, etc.
Buoy, pipe and other supporting equipment. When selecting dredging equipment, the main dredger is selected first, and then other auxiliary vessels are equipped to form a dredger team.
 
Steel pipe corrosion resistance is poor, but because of dredging construction is not convenient, short service life, is currently the most widely used PE dredge pipe, PE dredge pipe using high density polyethylene material production, corrosion resistance, abrasion resistance, long life and other characteristics, more and more applications and areas such as river dredging, my company production PE dredge pipe, it can fully meet your demand for dredging, mechanical flange connection, form a complete set of dredging floating body, the effect is much better!
