The key to the quality of thick wall steel pipe is the uniformity of wall thickness. If the wall thickness of thick wall steel pipe is not controlled, it will directly affect the quality and use of steel pipe. Thick wall steel pipe and large-diameter thick wall steel pipe are generally used in various machining and processing of thick wall parts. The uniformity of pipe wall of thick wall steel pipe will directly affect the quality of later processed parts, and the pipe wall of thick wall steel pipe can not be controlled, The quality of the whole steel pipe is not strictly controlled.

Suitable sites and warehouses shall be selected. The sites or warehouses for storing thick wall steel pipes shall be in clean places with smooth drainage, away from factories and mines that produce harmful gas or dust.

Weeds and all sundries shall be removed on the site to keep the thick wall steel pipe clean. It is not allowed to stack with acid, alkali, salt, cement and other materials that are corrosive to thick wall steel pipes in the warehouse. Thick wall steel pipes of different varieties shall be stacked separately to prevent confusion and contact corrosion. Large section steel, rail, steel plate, large-diameter thick wall steel pipe, forgings, etc. can be stacked in the open air.

Storage mode

Small and medium-sized section steel, wire rod, reinforcement, medium diameter thick wall steel pipe, steel wire and steel wire rope can be stored in a well ventilated shed, but they must be covered and padded. Some small thick wall steel pipes, steel sheets, steel strips, silicon steel sheets, small-diameter or thin-wall thick wall steel pipes, various cold-rolled and cold drawn thick wall steel pipes and metal products with high price and easy corrosion can be stored in the warehouse. The warehouse shall be selected according to geographical conditions. Generally, it adopts ordinary closed warehouse, that is, the warehouse with roof, enclosure, tight doors and windows and ventilation devices. The warehouse shall be ventilated in sunny days, closed in rainy days to prevent moisture, and always maintain a suitable storage environment. The principle of reasonable stacking and first in first stacking is to stack according to varieties and specifications under the condition of stable stacking and ensuring safety. Materials of different varieties shall be stacked separately to prevent confusion and mutual corrosion. It is prohibited to store items that have corrosive effect on thick wall steel pipes near the stacking position. In principle, section steels stacked in the open air must have wooden mats or strip stones under them, and the stacking surface is slightly inclined, In order to facilitate drainage, and pay attention to the flat and straight placement of materials to prevent bending and deformation. The stacking height shall not exceed 1.2m for manual operation, 1.5m for mechanical operation, and 2.5m for stack width. A certain channel shall be reserved between stacks. The inspection channel is generally o.5m, and the access channel depends on the size of materials and transportation machinery, generally 1.5 ~ 2.0m. The cushion height of stack bottom, If the warehouse is a Chaoyang cement floor, it can be padded up by 0.1M; If it is muddy ground, it must be padded 0.2 ~ 0.5m high. If it is an open-air site, the cement ground shall be padded 0.3 ~ o.5m and the sand and mud surface shall be padded 0.5 ~ o.7m. The open-air stacking of angle steel and channel steel shall be placed downward, that is, the I-beam shall be placed vertically, and the groove surface of thick wall steel pipe shall not be upward to avoid ponding and rust.

Pipe fitting

In addition to the above-mentioned structural types of pipe fittings used in actual piping engineering, there are other pipe fittings in various structural forms to meet the requirements of various working conditions, especially special working conditions. In engineering design or selection, the higher the strength grade of pipe fittings, the higher the safety, but the higher the cost of the project, which will cause unnecessary waste.

In terms of economic benefits, while meeting the engineering design requirements and reducing the cost as much as possible, it is often easy to form the selected pipe fittings. Generally, there are a small number and multiple varieties of results, which is unfavorable to the management and regulation of on-site construction materials and the substitution of materials required by design changes. Therefore, the selection of pipe fittings should integrate safety and economy, and reduce the variety of pipe fittings as much as possible. In addition, factors such as site construction conditions, construction level and procurement cycle of pipe fittings should also attract necessary attention in the selection of pipe fittings. In specific cases, the possibility of using reinforced pipe joints, mitered bends and on-site bending processing of small-diameter pipes shall also be considered.

At the same time, it is also necessary to understand the production capacity, products and market supply of pipe fittings manufacturers.
