3pe防腐鋼管執行標準：
3PE anti-corrosion performance standards:
SY/T0413-2002，規范聚乙烯與高密度聚乙烯為主，維卡軟化點定為不小于110℃。
SY/T0413-2002, specification for polyethylene and high density polyethylene, VEKA softening point is not less than 110 DEG C.
DIN30670-1991，規范外防腐層的厚度按以低、中密度聚乙烯為主。
DIN30670-1991, standardize anticorrosion layer thickness by low, medium density polyethylene.
SY/T0413-2002，將3PE防腐層的剝離強度、抗沖擊的指標大幅提高，并明確規定了據一些專用料炭黑含量，保證了3PE防腐層的機械強度和耐候性能，并加大了補口剝離強度（即熱縮套、熱縮帶的對底漆鋼的剝離強度）抽測頻次。
SY/T0413-2002, the peel strength, 3PE anticorrosion layer impact index improved significantly, and clearly specified according to some special material content of carbon black, the 3PE coating mechanical strength and weather resistance, and increase the coating peeling strength (i.e., heat shrinkable sleeve, heat shrinkable tape on the bottom paint peeling strength of pumping steel) measuring frequency
