Embodiment 1

[0027] see Figure 1-4 , a HDPE flat-sealed all-steel belt corrugated discharge pipe, its pipe wall includes a polyethylene inner layer 3 tightly fitted from the inside and outside, a spiral steel belt middle layer 4 and a polyethylene outer layer 5, and a spiral steel belt middle layer 4 The concave-convex steel strip 1 raised in the middle is spirally wound from one end to the other end (see image 3 , the cross-section of the steel strip protrusion is "∩" shape), and the edges of adjacent spiral units are provided with a number of through holes 2 and overlapped with each other. The through holes 2 are filled with polyethylene and connected with the polyethylene inner layer 3 The polyethylene outer layer 4 is connected as a whole; the pipe wall surface of the discharge pipe forms a trough 7 at the steel strip lap, and forms a wave crest 6 at the steel strip protrusion; the trough at the pipe end of the discharge pipe is filled with polyethylene and Cut to form a flat struct...

Embodiment 2

[0030] The production technology of the HDPE flat seal all-steel strip corrugated discharge pipe in embodiment 1 comprises the following steps:

[0031] (1) Steel strip material selection: the steel strip is selected as 20# carbon steel sheet with a width of 30mm-150mm and a thickness of 1.5mm-5.0mm;

[0032] (2) Polyethylene material ingredients: Mix 125-140 parts by weight of 2480 polyethylene particles and 1-1.2 parts by weight of color masterbatch; specifically: start the mixer, first pour polyethylene particles into the mixer without stopping the machine, Next, add the color masterbatch and stir evenly; pay attention to the mixing and stirring, and the silo of the mixer must be kept dry and free of impurities;

[0033] (3) Confine the steel belt on the transmission shaft of the conveyor, start the transmission and pass through the punching machine and the forming machine in turn, that is, first use the forging punching method to punch holes on both sides of the steel belt...

Abstract

The invention discloses an HDPE flatly sealed all-steel-belt corrugated discharging tube and a production technology. A tube wall of the HDPE flatly sealed all-steel-belt corrugated discharging tube comprises a polyethylene inner layer, a spiral steel belt middle layer and a polyethylene outer layer which are tightly attached from inside to outside, wherein the spiral steel belt middle layer is formed by sequentially spirally winding concave and convex steel belts from one end to the other end; a plurality of through holes are formed in edges of adjacent spiral units which are in lap joint correspondingly; the through holes are filled with polyethylene and are connected with the polyethylene inner layer and the polyethylene outer layer to form a whole body; troughs are formed in steel belt lap joint positions of the surface of the tube wall of the discharging tube; crests are formed at steel belt projections; the troughs in ends of the discharging tube are filled with polyethylene so that flat end structures are formed at the ends of the discharging tubes. Plastic-steel separation is realized through the design of the connecting steel belts, continuity of the steel belts and integrity of the tube can be realized, and the compressive property of the tube can be guaranteed. In addition, the ends of the discharging tube are flat, so that flat sealing can be convenient to implement when tubes are in butt joint or are mounted in a wellhead, and construction quality is guaranteed.

Description

technical field [0001] The invention relates to the field of pipe materials, in particular to a steel strip corrugated discharge pipe and a production process. Background technique [0002] Steel belt corrugated pipe is a new type of pipe that has appeared in recent years. It is economical, durable and environmentally friendly and has been widely promoted. The traditional steel belt reinforced polyethylene spiral corrugated pipe is composed of inner polyethylene, spiral steel belt and outer polyethylene spiral corrugated pipe body. Because of its internal smoothness, strong external pressure resistance, corrosion resistance and many other advantages, it can be used It is widely used in various drainage and sewage systems used in municipal, industrial, agricultural and traffic engineering constructions. The steel belt in the traditional steel belt polyethylene spiral corrugated pipe is not continuous spiral coiling, that is, the adjacent spiral units are spaced apart from ea...
