Embodiment Construction

[0021] The present invention will be described in further detail below in conjunction with the accompanying drawings and through specific embodiments. The following embodiments are only descriptive, not restrictive, and cannot sequentially limit the protection scope of the present invention.

[0022] A suspended plastic-coated hot-dipping equipment for steel pipes with good airtightness, including a rotating bracket, a suspension box and a negative pressure cover. Sliding forward is driven by the cylinder 13, and a steel pipe chuck 10 is coaxially hinged on the hinge seat top, and the steel pipe chuck adopts a motor 1 to drive and rotate. The two rotating brackets are arranged symmetrically, and the two steel pipe chucks are coaxially corresponding to each other, respectively supporting the two ends of the steel pipes, and the rotation of the steel pipe chucks drives the steel pipes to rotate.

[0023] A suspension box 5 is set between the two rotating supports, the upper surf...

Abstract

The invention relates to suspension type steel tube outer plastic-coating and hot-dipping equipment with a good sealing property. The suspension type steel tube outer plastic-coating and hot-dipping equipment comprises a rotary bracket, a suspension box and a negative-pressure cover, wherein the suspension box body side walls on the outer edges of an arc-shaped blocking slot of the suspension boxare hinged with arc-shaped sealing strips through pin rolls; a soft sealing edge is coaxially embedded into each arc-shaped sealing strip; limiting rods are arranged at upper and lower sides of each arc-shaped blocking slot; and a magnet is embedded into a fiber rod on the upper part. The two sides of the suspension box of the suspension type steel tube outer plastic-coating and hot-dipping equipment with good sealing property provided by the invention are equipped with the arc-shaped sealing strips, so that the arc-shaped blocking slots in the two sides can be sealed, and therefore, powder and smoke gas are guaranteed to not leak, production space further can be purified, and the smoke gas removal effect is further improved.

Description

technical field [0001] The invention belongs to the field of plastic coating of steel pipes, and is a suspension-type plastic-coating hot dipping equipment for steel pipes with good sealing performance. Background technique [0002] At present, plastic-coated steel pipe is a new type of high-efficiency anti-corrosion steel, which has excellent anti-corrosion performance, high compressive strength, long service life, smooth inner surface, good liquid flow performance, etc., making it quickly recognized by the market. Plastic-coated steel pipes are formed by melting a layer of polyethylene resin, ethylene-acrylic acid copolymer, epoxy powder, non-toxic polypropylene or non-toxic polyvinyl chloride and other organic substances with a thickness of 0.5-1.0mm on the inner or outer wall of the steel pipe. The composite pipe makes it have the advantages of high strength, easy connection, water impact resistance and so on. [0003] The existing steel pipe outer plastic coating techn...
