WebHigh-density polyethylene ( HDPE) or polyethylene high-density ( PEHD) is a thermoplastic polymer produced from the monomer ethylene. It is sometimes called "alkathene" or "polythene" when used for HDPE pipes. [1] With a high strength-to-density ratio, HDPE is used in the production of plastic bottles, corrosion-resistant piping, geomembranes ... WebFillet Welds 0.8mm per weld where the leg length does not exceed 3/4 plate thickness. Butt weld 1.5 to 3mm per weld for 60° V joint, depending on number of runs. Longitudinal shrinkage. Fillet Welds 0.8mm per 3m of weld. Butt Welds 3mm per 3m of weld. Increasing the leg length of fillet welds, in particular, increases shrinkage.
