When purchasing seamless steel tubes, the choice of measurement unit directly impacts procurement costs and material utilization. Understanding the difference between "pricing by weight" and "pricing by length" is a fundamental skill every procurement professional must master. The correct measurement method not only avoids unnecessary losses but also ensures the smooth progress of projects.

Applications of Weight-Based Pricing

Purchasing seamless steel tubes by weight (kilograms/ton) is a relatively traditional approach, primarily suitable for standard specification products. This pricing method is based on the theoretical weight of the steel tube, calculated using the formula: (outer diameter - wall thickness) × wall thickness × 0.02466. Its advantage lies in simple calculation and ease of cost accounting, making it particularly suitable for large-volume purchases.

However, weight-based pricing also has obvious limitations. Due to the wall thickness tolerance of seamless steel tubes, the actual weight may deviate from the theoretical weight. Changzhou Tenjan Steel Pipe Co., Ltd. reminds customers that when purchasing by weight, special attention should be paid to the wall thickness tolerance range to avoid material shortages caused by negative tolerance.

Advantages of Length-Based Pricing

Pricing by length (meter) is more suitable for customized seamless steel tube procurement. This method is straightforward, allowing the buyer to precisely control the required material quantity and avoid waste. Especially in engineering projects requiring specific lengths, pricing by meter ensures maximum material utilization.

For seamless steel tubes with special specifications, pricing by length offers even greater advantages. Changzhou Tenjan Steel Pipe Co., Ltd. recommends prioritizing length-based pricing when purchasing non-standard products or in situations requiring precise cutting. Although the unit price may be higher, this method effectively reduces leftover material loss, potentially resulting in lower overall costs.

Professional Advice on Choosing Pricing Methods

When selecting a pricing method, several factors need consideration. For conventional projects, pricing by weight is more economical; for precision engineering, pricing by length better guarantees accuracy. Order quantity is also an important reference: large-volume purchases suit weight-based pricing, while small-batch custom orders are more suitable for length-based pricing.

Professionals from Changzhou Tenjan Steel Pipe Co., Ltd. recommend that when requesting quotes, buyers should ask suppliers to provide comparisons of both pricing methods and make the best choice based on project requirements. Simultaneously, regardless of the chosen method, it's essential to specify the measurement standard in the contract to avoid subsequent disputes.
