preventive measure

(1) Heavy vessels must keep away from wind and waves in time all through navigation;

(2) The overall performance of ballast valve is exact;

(3) It is essential to pick out appropriate ships with small age, exact deliver kind and exact hatch seal.

Fresh water rust

It is in particular because of rain; a part of it's miles because of the excessive packaging temperature,which makes the coil temperature excessive internal and occasional outside,ensuing in inner condensation and corrosion.

preventive measure 

(1) Avoid operating withinside the open on wet days;

(2) Rain material on board;

(3) Select an appropriate deliver with precise tightness of hatch cowl (or cowl the hatch cowl with rain material);

(four) Strictly manipulate the packaging temperature and humidity of bloodless rolled coil;

(5) Use of all-climate Wharf

2 rust at the railway

It is because of the rain withinside the technique of loading and unloading or transportation out of doors the railway, which reasons the rain to go into the wagon and influences the goods.

preventive measure

What is spiral welded pipe?
Spiral steel pipe is a spiral welded steel tube made of strip steel coil as raw material and often formed by warm extrusion.The spiral steel tube feeds the strip into the welding tube unit, and after rolling with multiple rollers, the strip is gradually rolled up to form a round tube blank with open clearance. The pressure reduction of the extrusion roller is adjusted so that the
weld clearance is controlled at 1~3mm and both ends of the welding joint are flush.
What are the advantages of spiral welded pipe?
Spiral pipe features: straight seam welded pipe production process is simple, high production efficiency, low cost, rapid development.Spiral welded pipe generally has higher strength than straight welded pipe. Welded pipe with larger pipe diameter can be produced from narrow blank, and welded pipe with different pipe diameter can also be produced from blank of the same width.
