Khoom Description
Peb yog cov chaw tsim khoom ntawm cov kav dej dredger, peb lub Hoobkas tau tsim nyob rau xyoo 2009 nrog thaj tsam ntawm 26000 square hauv Weishan county. Shandong Xincheng muaj 10 xyoo kev paub ntawm kev tsim khoom thiab muag cov yeeb nkab dredging. Nws cov kav dej dredging tau txais kev qhuas ntau thiab lub koob npe nrov ntawm cov neeg siv khoom thoob plaws ntiaj teb.
HDPE yeeb nkab yog tsim los ntawm hnav resistant HDPE tov nrog anti-UV khoom los ntawm extrusion molding tshuab.. HDPE kav muaj tshwj xeeb cov khoom xws li corrosion kuj thiab lub teeb yuag uas ua rau lawv xaiv zoo tshaj plaws rau dredging neeg cog lus.
Cov qauv thiab kev sib txuas ntawm Dredging HDPE Pipes
1. Enlarged kawg, lossis flare kawg qee tus neeg hu, Tsis xav tau vuam.
2. Nodular cam khwb cia hlau ntxig rau thaum kawg los tiv thaiv nws ntawm deformation, tawg thiab to
3. Loose flang rings (carbon steel, galvanized) ntawm ob qhov kawg
4. Roj hmab gasket nyob nruab nrab ntawm thaum ob lub kav dej txuas nrog bolts thiab ceev.
Qhov zoo ntawm cov kav dej tso tawm
1. Lub teeb yuag, yooj yim rau transportaion thiab installation.
2. Zoo yooj, tensille quab yuam thiab lub zog.
3. Muaj zog hnav tsis kam & corrosion kuj
4. Flared xaus, tsis muaj vuam, xoob flanges ntawm ob qho kawg.
5. Smooth puab phab ntsa, me me kev sib txhuam coefficient.
6. Ib puag ncig tus phooj ywg.
Xincheng manufactures dredging HDPE yeeb nkab los ntawm OD110mm mus rau 1000mm, qhov ntau thiab tsawg yog raws li nram no:
