Problems solved by technology

Although the accident rate of the stainless steel bellows has been significantly reduced, there are still the following deficiencies: First, the bellows burst or pinholes are caused by stainless steel material problems, welding and surface treatment problems, and acid corrosion problems in the gas. Second, the price of stainless steel bellows is generally high; third, stainless steel bellows for gas are not soft enough to completely replace rubber hoses, especially It is a working condition with small bending radius and frequent construction; fourth, it is not compatible with various types of gas interfaces

Embodiment 1

[0032] The invention provides a stainless steel thin-wall corrugated pipe lined with waste plastics and its preparation process. The waste plastics and auxiliary materials including the following components and their mass parts are used as the lining materials: waste PVC 77kg, peroxide masterbatch 8kg, 13kg of small molecule monomer masterbatch, 0.8kg of stearate, 7kg of flame retardant, 1.2kg of graphite, using nickel-based alloy stainless steel thin-walled steel strip with a thickness of 2.5mm as the tube wall material, processed through the following steps:

[0033] 1) Coil welding:

[0034] Put the thin-walled nickel-based alloy stainless steel strip into the automatic plate rolling machine and roll it into a tubular shape and shape it. At the pre-welding position (that is, the pre-joining position of the steel strip), make opposite grooves on both sides, and the groove is a 60° V-shaped groove. type groove; the inner wall of the mechanical mold is fixed, and the automatic...

Embodiment 2

[0047] The invention provides a stainless steel thin-walled corrugated pipe lined with waste plastics and its preparation process, using waste plastics and auxiliary materials including the following components and their mass parts as the lining materials: 80kg of waste PVC, 5kg of peroxide masterbatch, 10kg of small molecule monomer masterbatch, 0.5kg of stearate, 5kg of flame retardant, 2kg of graphite, with a thickness of 2.5mm nickel-based alloy stainless steel thin-walled steel strip as the pipe wall material, the preparation process is the same as that of Example 1, the difference in:

[0048] The passivation potion includes the following components and their mass parts: 15kg of aminotrimethylene phosphoric acid, 2kg of phosphate, 2kg of boric acid, 0.5kg of organic acid, 0.5kg of organic silicon, 1kg of flocculant, and 79kg of water.

Embodiment 3

[0050] The invention provides a stainless steel thin-wall corrugated pipe lined with waste plastics and its preparation process. The waste plastics and auxiliary materials including the following components and their mass parts are used as the lining materials: waste PVC 70kg, peroxide masterbatch 10kg, 5kg of small molecule monomer masterbatch, 1kg of stearate, 10kg of flame retardant, 0.2kg of graphite, with a thickness of 2.5mm nickel-based alloy stainless steel thin-walled steel strip as the pipe wall material, the preparation process is the same as that of Example 1, the difference in:

[0051] The passivation potion includes the following components and their mass parts: 5 kg of aminotrimethylene phosphoric acid, 5 kg of phosphate, 0.5 kg of boric acid, 2 kg of organic acid, 2 kg of organic silicon, 0.5 kg of flocculant, and 85 kg of water.

Abstract

The invention provides a waste plastic cylinder packing stainless steel thin wall corrugated pipe and a manufacture process thereof. The waste plastic and auxiliary materials comprising by weight, 70-80 parts of waste PVC, 5-10 parts of peroxide master batch, 10-15 parts of small molecule master batch, 0.5-1 parts of stearate, 5-10 parts of fire retardant and 0.2-2 parts of graphite are taken as cylinder packing, a nickel base alloy stainless steel thin wall steel band is taken as a pipe wall material, and the waste plastic cylinder packing stainless steel thin wall corrugated pipe is processed by means of coil welding, corrugated molding, heat treatment, acidic passivation and waste plastic cylinder packing. The waste plastic cylinder packing stainless steel thin wall corrugated pipe is advantaged by being low in cost, high in corrosion resistance and resistance to stress change, good in toughness and flame retardation and heat insulation effect, and being compatible with all types of gas interfaces and the like, for the manufacture process, a conventional pickling step is avoided, and the fact that the conventional pickling step is avoided is a major innovation in the energy saving and environmental protection aspect.

Description

technical field [0001] The invention relates to the technical field of daily necessities manufacturing, in particular to a stainless steel thin-wall corrugated pipe lined with waste plastics and a preparation process thereof. Background technique [0002] Stainless steel corrugated pipes for gas are generally made of high-quality austenitic stainless steel tube billets or austenitic stainless steel strips, and then processed into corrugated flexible tubular shells by machining. constant. Stainless steel bellows are very convenient to install, can effectively compensate for installation displacement deviation, and the product has good strength, anti-rat bite, corrosion resistance, long service life, and can effectively solve the problems of pipeline damage caused by aging, corrosion, bursting, leakage, etc. . As far as the current stainless steel corrugated pipes are used for connecting gas appliances, the general working conditions are gas stoves, wall-mounted stoves, gas ...
