The invention relates to a polyethylenecoating elbow, producing method and the equipment.
本发明涉及一种聚乙烯涂装弯管及其制造方法和设备。
2
Polyethylenecoating reduced the degree of ADI water embrittlement, but nylon or epoxy coatings had no effect on ADI water embrittlement prevention.
聚乙烯涂覆能降低adi的水脆化程度，而环氧树脂和尼龙涂覆无防止ADI水脆化的效果。
3
The steel elbow is used as the base stock for polyethylenecoating elbow and no-interface circular polyethylene material is coated to the outside of steel elbow.
