Topic for chemical composition in steel pipe

Different chemical composition would cause big difference on steel pipe’s characters. So it is necessary to decide the volume of chemical composition before the production for seamless steel pipe, ERW steel pipe and other steel pipe.

1. Plate analysis: It is our dominant work to analyze each mill's heat of plate material before steel pipe's production. This would lead to the good quality of meeting the requirements of the plate specification to which the material was ordered.

2. Weld parameter's analysis: Pipe manufacturer need to make an analysis for the finished deposited weld material. This would conform to the welding procedure for deposited welded metal.

Under this situation, making a list for the detailed information would be necessary. For example: the Seamless Steel Pipe ASTM A213 from Threewaysteel Co. Ltd

Standard: ASME SA 213  American society of mechanical engineers; ASTM A213M American society for Testing and Materials

Uses: For manufacture wall panel, economizer, reheater, superheater and steam pipeline of boilers.
