Трубный экспандер по п. 2, в котором на поверхностях контакта вкладыша и элемента наружной поверхности расширительной головки величина твердости более мягкого элемента составляет 30 HS или более.4. The pipe expander according to claim 2, in which on the contact surfaces of the liner and the element of the outer surface of the expansion head, the hardness of the softer element is 30 HS or more. 5. Трубный экспандер по п. 3, в котором на поверхностях контакта вкладыша и элемента наружной поверхности расширительной головки величина твердости более мягкого элемента составляет 30 HS или более.5. The pipe expander according to claim 3, in which on the contact surfaces of the liner and the element of the outer surface of the expansion head, the hardness of the softer element is 30 HS or more. 6. Трубный экспандер по п. 2, в котором более мягким элементом является вкладыш.6. The pipe expander according to claim 2, wherein the softer element is the insert. 7. Трубный экспандер по п. 3, в котором более мягким элементом является вкладыш.7. The pipe expander according to claim 3, wherein the softer element is the insert. 8. Трубный экспандер по п. 4, в котором более мягким элементом является вкладыш.8. The pipe expander according to claim 4, wherein the softer element is the insert. 9. Трубный экспандер по п. 5, в котором более мягким элементом является вкладыш.9. The pipe expander according to claim 5, wherein the softer element is the liner. 10. Трубный экспандер по любому из пп. 1-9, в котором вкладыш изготовлен из медного сплава.10. Pipe expander according to any one of paragraphs. 1-9, in which the liner is made of a copper alloy.
