. Base material

 

Longitudinally welded steel pipes for constructions are manufactured from hot rolled steel strips according to STAS 908 and STAS 9236 from the steel types St. 32 and St. 37 according to STAS 500/2.
Note: On agreement, there can be pipes manufactured from other steel types, with tensile strength of 440 N/mm2.


5. Other quality checks

- bend testing (at customer's choice);
- flattening test (at customer's choice);
- electromagnetic testing;
- checking of chemical analysis on pipe (at customer's choice).

DELIVERY, MARKING, PACKING, DOCUMENTS

- the pipes are delivered unprotected;
- the pipes are delivered with bevelled unthread ends and not internally debbured, in bundles with fixed number of pieces, packed in hexagonal shape, tied in minimum five places with steel strips;
- a tag will be attached to each bundle;
- each lot of pipes will be accompanied by the mill test certificate according to EN 10204;
- the delivery will be made by railway, truck or ship.
